AB  - Class III peroxidases (POXs; EC. 1.11.1.7), are secretory, multifunctional plant enzymes that catalyze the oxidation of a variety of substrates by hydrogen peroxide (H2O2). They show a remarkable diversity of isoenzymes, are encoded by a large number of paralogous genes, and are involved in a broad range of metabolic processes throughout plant growth and development. Peroxidases isoenzymes are located in the cell wall, apoplast and vacuole, and may be either soluble or ionically and covalently cell wall bound. They are involved in cell wall cross-linking and loosening, lignification and suberization, auxin catabolism and secondary metabolism. Due to their ability to control the levels of reactive oxygen species (ROS), POXs are efficient components of the antioxidative system induced in response to environmental stress, such as pathogen attack, metal excess, salinity, drought and high light intensity. In addition to the peroxidative function, POXs can catalyze H2O2 production in the oxidative cycle. Peroxidases are responsible either for cell elongation or cell wall stiffening, affecting carbon allocation, auxin level and redox homeostasis, which implicates their key role as being in the regulation of growth and defence under stress condition. This chapter will discuss novel insights into the functions of PODs with special emphasis on their localization, substrate specificity and the regulation of redox homeostasis.

AB  - During their lifespan, plants are frequently exposed to adverse environmental conditions such as high solar irradiance, drought, heat, chilling, salinity, metal excess, and nutrient deficiency. The effects of these factors on plants are often interrelated and usually result in a decreased capacity of carbon fixation in photosynthesis, disturbed redox homeostasis, and growth arrest. Under severe conditions, increased excitation pressure in the chloroplasts exceeds the antioxidative capacity of plant cells leading to oxidative damage of cellular constituents. Although the plant ascorbate (Asc) level varies depending on external factors, developmental stage, diurnal rhythm, and light, its redox status is related to redox homeostasis in the cell. In chloroplasts, peroxisomes, and cytosol, Asc has a key role in hydrogen peroxide (H2O2) scavenging via Asc peroxidase and is efficiently recycled via the ascorbate-glutathione (Asc-GSH) cycle and directly by monodehydroascorbate reductase activity. In apoplast and vacuoles, Asc is the main reductant of phenolic radicals generated under oxidative stress. Besides its antioxidative role, Asc has an important role in a complex and well-orchestrated plant response network to environmental stress, performing multiple tasks in redox signalling, regulation of enzymatic activities, modulation of gene expression, biosynthesis of phytohormones, and growth regulation. The content of Asc and its redox state is tightly related to cellular compartments. Therefore, it is important to emphasize Asc cellular distribution, which has a great impact on reactive oxygen species regulation and signalling. Numerous studies on transgenic plants with altered endogenous Asc levels and redox status were done with the aim to influence plant growth and improve tolerance to various abiotic stressors. In this chapter, we discuss the current understanding of the involvement of Asc metabolism in abiotic stress response. Moreover, the improved resilience to stressors in transgenic plants with altered enzymes involved in Asc biosynthesis and recycling will be discussed.

AB  - We investigated metal accumulation in bamboo leaves during three seasons at three urban locations differing in pollution levels. The higher content of Cu, Pb, and Zn in the leaves was in correlation with the highest bioavailable content of these elements in the soil at the most polluted location. The content of leaf trace elements was higher in summer and autumn compared to spring. Scanning electron microscopy with energy dispersive X-ray spectroscopy showed that Si accumulation in bamboo leaves was the highest in epidermis and vascular tissue, and was co-localized with trace metals. Analysis of phytoliths showed co-deposition of Al, C, and Si, implying the involvement of Si in metal detoxification. Compared to a common urban tree, linden, bamboo showed better capacity to maintain cellular redox homeostasis under deteriorated environmental conditions. The results suggest that bamboo can be efficiently used for biomonitoring of air and soil metal pollution and remediation in urban areas.

AB  - In their natural environment, plants are constantly exposed to dynamic changes of solar
radiation, which mainly consists of infrared (IR, >700 nm), photosynthetically active radiation
(PAR, 400-700 nm) and minor portion of ultraviolet (UV) radiation (UV-B, 290-315 nm and
UV-A, 315-400 nm). Sunlight is not only the primary source of energy in photosynthesis, it is
also an important signal which regulates plant growth and development. During the period
from the 1970s to 1990s, investigations on UV‐B effects on organisms were in the centre of
attention due to alarming depletion of stratospheric ozone layer and increased UV‐B radiation
reaching the Earth’s surface. UV-B radiation has been perceived only as a stressor. A decade
later, new data obtained using realistic UV-B doses and realistic UV-B:UV-A:PAR ratio,
clearly show that UV-B is very important environmental cue and regulator of plant
metabolism, rather than a stressor. In the recent years, great progress has been made in
understanding the mechanisms of light signals’ perception. However, the complications arise
from the overlapping of the acclimative responses to UV‐B radiation and high PAR intensity,
imposing cross‐tolerance to different components of solar radiation. Moreover, information on
other constituents involved in the UV‐B response, such as reactive oxygen species in relation to
their tissue- and subcellular-localization is scarce. Our latest findings using leaf variegation as
a model with metabolically contrasting tissues show specific responses to UV-B radiation and
high light in relation to antioxidative metabolism, photosynthesis, carbohydrate metabolism,
and distribution of phenolics.

AB  - Tomato (Solanum lycopersicum L.) is among the economically most important vegetables in Europe, valued for its bioactive properties due to significant contents of vitamins, carotenoids, and phenolic compounds. In this study, the tomato cultivar Big Beef F1 was grown in the open field (OF) and under polytunnels in central Serbia during 3 years. Polytunnels were covered with two foils (both with 57% reduced photosynthetic active radiation, PAR) differing in UV-A and UV-B transmittance. The aim of our work was to determine the influence of light conditions on accumulation of phytonutrients (carotenoids and phenolics) in the peel and flesh of ripe tomato fruits. The amount of effective antioxidants, caffeic acid, and quercetin (phenolics with ortho-dihydroxy substitution) in the peel was the highest in tomato fruits grown in the OF (maximal PAR and UV-A and UV-B radiation). Moreover, the content of leaf epidermal flavonoids was the highest in the OF. The content of lycopene and beta-carotene in the flesh of tomato fruit was higher under the polytunnel with higher UV-transmittance. Our results showed that selection of the right light conditions (quality and intensity) for tomato production has a significant effect on the accumulation of beneficial phenolics and carotenoids.

AB  - Hydrogen peroxide is an important signalling molecule, involved in regulation of numerous metabolic processes in plants. The most important sources of H2O2 in photosynthetically active cells are chloroplasts and peroxisomes. Here we employed variegated Pelargonium zonale to characterise and compare enzymatic and non-enzymatic components of the antioxidative system in autotrophic and heterotrophic leaf tissues at (sub)cellular level under optimal growth conditions. The results revealed that both leaf tissues had specific strategies to regulate H2O2 levels. In photosynthetic cells, the redox regulatory system was based on ascorbate, and on the activities of thylakoid-bound ascorbate peroxidase (tAPX) and catalase. In this leaf tissue, ascorbate was predominantly localised in the nucleus, peroxisomes, plastids and mitochondria. On the other hand, non-photosynthetic cells contained higher glutathione content, mostly located in mitochondria. The enzymatic antioxidative system in non-photosynthetic cells relied on the ascorbate-glutathione cycle and both Mn and Cu/Zn superoxide dismutase. Interestingly, higher content of ascorbate and glutathione, and higher activities of APX in the cytosol of non-photosynthetic leaf cells compared to the photosynthetic ones, suggest the importance of this compartment in H2O2 regulation. Together, these results imply different regulation of processes linked with H2O2 signalling at subcellular level. Thus, we propose green-white variegated leaves as an excellent system for examination of redox signal transduction and redox communication between two cell types, autotrophic and heterotrophic, within the same organ.

Here we employed variegated Pelargonium zonale to characterise and compare enzymatic and non-enzymatic components of the antioxidative system in autotrophic and heterotrophic leaf tissues at (sub)cellular level under optimal growth conditions. The results revealed that both leaf tissues had specific strategies to regulate H2O2 levels. In photosynthetic cells, the redox regulatory system was based on ascorbate, and on the activities of thylakoid-bound ascorbate peroxidase (tAPX) and catalase. In this leaf tissue, ascorbate was predominantly localised in the nucleus, peroxisomes, plastids and mitochondria. On the other hand, non-photosynthetic cells contained higher glutathione content, mostly located in mitochondria. The enzymatic antioxidative system in non-photosynthetic cells relied on the ascorbate-glutathione cycle and both Mn and Cu/Zn superoxide dismutase. Interestingly, higher content of ascorbate and glutathione, and higher activities of APX in the cytosol of non-photosynthetic leaf cells compared to the photosynthetic ones, suggest the importance of this compartment in H2O2 regulation. Together, these results imply different regulation of processes linked with H2O2 signalling at subcellular level. Thus, we propose green-white variegated leaves as an excellent system for examination of redox signal transduction and redox communication between two cell types, autotrophic and heterotrophic, within the same organ.",

AB  - Green-white variegated leaves of Pelargonium zonale were studied using the photoacoustic method. Our aim was to characterize photosynthetically active green tissue and nonphotosynthetically active white tissue by the photoacoustic amplitude signals. We observed lower stomatal conductance and higher leaf temperature in white tissue than in green tissue. Besides these thermal differences, significantly higher absorbance in green tissue was based on chlorophyll and carotenoids which were absent in white tissue. However, optical properties of epidermal layers of both tissues were equal. The photoacoustic amplitude of white tissue was over four times higher compared to green tissue, which was correlated with lower stomatal conductance. In addition, at frequencies  gt 700 Hz, the significant differences between the photoacoustic signals of green and white tissue were obtained. We identified the photoacoustic signal deriving from photosynthetic oxygen evolution in green tissue, using high intensity of red light modulated at 10 Hz. Moreover, the photoacoustic amplitude of green tissue increased progressively with time which corresponded to the period of induction of photosynthetic oxygen evolution. For the first time, very high frequencies (1 kHz to 5 kHz) were applied on leaf material.

AB  - Plants as well as other aerobic organisms constantly produce reactive oxygen species (ROS). At regulated low concentrations ROS may serve as signal molecules, while in excessive amounts these may cause oxidative damage to biomolecules. Actual cellular concentrations are controlled by a network of various antioxidants, and acclimation to stress conditions is achieved by a dynamic balance of ROS production and neutralization. Accordingly, plant stress physiology studies generally include an array of methods testing the occurrence of ROS as well as evaluating antioxidant capacities. The aim of the present work is to provide an overview of these methods, with special emphasis on avoiding errors that can possibly lead to either inaccurate data or misinterpretations of otherwise correct measurements.

AB  - In this study we exposed variegated leaves of Pelargonium zonale to strong sunlight ( gt 1100 mu mol m(-2) s(-1) of photosynthetically active radiation) with and without paraquat (Pq), with the aim to elucidate the mechanisms of H2O2 regulation in green and white tissues with respect to the photosynthetically-dependent generation of reactive oxygen species (ROS). Sunlight induced marked accumulation of H2O2 in the apoplast of vascular and (peri)vascular tissues only in green sectors. This effect was enhanced by the addition of Pq. In the presence of diphenyl iodide, an NADPH oxidase inhibitor, H2O2 accumulation was abolished. Distinct light-induced responses were observed: in photosynthetic cells, sunlight rapidly provoked ascorbate (Asc) biosynthesis and an increase of glutathione reductase (GR) and catalase activities, while in non-photosynthetic cells, early up-regulation of soluble ascorbate peroxidase, dehydroascorbate reductase (DHAR) and GR activities was observed. Paraquat addition stimulated DHAR and GR activities in green sectors, while in white sectors activities of monodehydroascorbate reductase, DHAR and class III peroxidases, as well as Asc content rapidly increased. Differential antioxidative responses in the two tissues in the frame of their contrasting metabolisms, and the possible role of (peri)vascular H2O2 in signaling were discussed.

AB  - We used variegated Plectranthus coleoides as a model plant with the aim of clarifying whether the effects of realistic ultraviolet-B (UV-B) doses on phenolic metabolism in leaves are mediated by photosynthesis. Plants were exposed to UV-B radiation (0.90Wm(-2)) combined with two photosynthetically active radiation (PAR) intensities [395 and 1350molm(-2)s(-1), low light (LL) and high light (HL)] for 9d in sun simulators. Our study indicates that UV-B component of sunlight stimulates CO2 assimilation and stomatal conductance, depending on background light. UV-B-specific induction of apigenin and cyanidin glycosides was observed in both green and white tissues. However, all the other phenolic subclasses were up to four times more abundant in green leaf tissue. Caffeic and rosmarinic acids, catechin and epicatechin, which are endogenous peroxidase substrates, were depleted at HL in green tissue. This was correlated with increased peroxidase and ascorbate peroxidase activities and increased ascorbate content. The UV-B supplement to HL attenuated antioxidative metabolism and partly recovered the phenolic pool indicating stimulation of the phenylpropanoid pathway. In summary, we propose that ortho-dihydroxy phenolics are involved in antioxidative defence in chlorophyllous tissue upon light excess, while apigenin and cyanidin in white tissue have preferentially UV-screening function.

AB  - We studied the specific effects of high photosynthetically active radiation (PAR, 400-700 nm) and ecologically relevant UV-B radiation (0.90 W m(-2)) on antioxidative and phenolic metabolism by exploiting the green-white leaf variegation of Pelargonium zonale plants. This is a suitable model system for examining "source-sink" interactions within the same leaf. High PAR intensity (1350 mu mol m(-2) s(-1)) and UV-B radiation induced different responses in green and white leaf sectors. High PAR intensity had a greater influence on green tissue, triggering the accumulation of phenylpropanoids and flavonoids with strong antioxidative function. Induced phenolics, together with ascorbate, ascorbate peroxidase (APX, EC 1.11.1.11) and catalase (CAT, EC 1.11.1.6) provided efficient defense against potential oxidative pressure. UV-B-induced up-regulation of non-phenolic H2O2 scavengers in green leaf sectors was greater than high PAR-induced changes, indicating a UV-B role in antioxidative defense under light excess; on the contrary, minimal effects were observed in white tissue. However, UV-B radiation had greater influence on phenolics in white leaf sections compared to green ones, inducing accumulation of phenolic glycosides whose function was UV-B screening rather than antioxidative. By stimulation of starch and sucrose breakdown and carbon allocation in the form of soluble sugars from "source" (green) tissue to "sink" (white) tissue, UV-B radiation compensated the absence of photosynthetic activity and phenylpropanoid and flavonoid biosynthesis in white sectors.

AB  - To investigate metal specific responses of root class III peroxidases (POD, EC 1.11.1.7), two populations of Verbascum thapsus L. were exposed to excess Zn2+ or Cu2+ for three weeks in hydroponic culture. One population originating from an uncontaminated area (NMET) and one from an industrial disposal area for jarosite residues from zinc refining (MET) were chosen to test the capacity of V. thapsus to adapt to excess metal in the soil. Exposure to 60 μM Zn2+ led to increased levels of protein carbonyl groups only in the roots of NMET, which was accompanied by higher increase of POD activity and NADH-oxidase activity compared with MET plants. New anionic and cationic POD isoforms were induced in the roots of both populations in response to Zn2+ treatment, while IAA-oxidase activity decreased. On the other hand, root growth was more affected by Cu2+ than Zn2+ in both populations, which was correlated with increased auxin-oxidase (IAA-oxidase) activity. Cu2+ induced an increased activity of anionic POD isoforms in the roots of both populations, yet the ratio of NADH-oxidative to peroxidative POD activity remained higher in NMET than in MET plants. Overall results show differential effects of Zn2+ and Cu2+ on POD activity in the roots of V. thapsus L. In addition, higher tolerance to Zn2+ in MET plants than in NMET indicated that these plants have developed an adaptive mechanism to cope with Zn2+ excess.

AB  - We used variegated Plectranthus coleoides as a model plant with the aim of clarifying whether the effects of realistic ultraviolet-B (UV-B) doses on phenolic metabolism in leaves are mediated by photosynthesis. Plants were exposed to UV-B radiation (0.90Wm(-2)) combined with two photosynthetically active radiation (PAR) intensities [395 and 1350molm(-2)s(-1), low light (LL) and high light (HL)] for 9d in sun simulators. Our study indicates that UV-B component of sunlight stimulates CO2 assimilation and stomatal conductance, depending on background light. UV-B-specific induction of apigenin and cyanidin glycosides was observed in both green and white tissues. However, all the other phenolic subclasses were up to four times more abundant in green leaf tissue. Caffeic and rosmarinic acids, catechin and epicatechin, which are endogenous peroxidase substrates, were depleted at HL in green tissue. This was correlated with increased peroxidase and ascorbate peroxidase activities and increased ascorbate content. The UV-B supplement to HL attenuated antioxidative metabolism and partly recovered the phenolic pool indicating stimulation of the phenylpropanoid pathway. In summary, we propose that ortho-dihydroxy phenolics are involved in antioxidative defence in chlorophyllous tissue upon light excess, while apigenin and cyanidin in white tissue have preferentially UV-screening function.

AB  - Phenolic compounds are one of the most important groups of secondary metabolites in plants, with various physiological functions. Their diverse chemical structure and susceptibility to auto-oxidation, and their ability to act as both antioxidants and prooxidants in the presence of metal ions, are some of the main reasons why it is difficult to measure phenolic groups in plant tissues accurately. We present an optimized extraction and hydrolysis procedure which preserves the original chemical structure of phenolics. The presented HPLC method was improved to enable the simultaneous separation and quantification of 39 compounds from different phenolic subclasses (benzoic acids, hydroxycinnamic acids, flavones, flavonols, flavanones, flavanols, isoflavones, anthocyanidins; aglycones and glycosides). Recovery after extraction and complete hydrolysis of glycosides was more than 95% and 84%, respectively. The method was applied to the analysis and comparison of phenolic profiles in the leaves of two species, Ailanthus altissima (Mill.) Swingle and Tilia platyphyllos Scop. from an urban forest park and busy traffic area. The presence of cyanidin glycosides in A. altissima leaves was reported for the first time. Results indicated higher accumulation of phenolics, with two hydroxyl groups in the ortho- position, than flavonoids, with a monohydroxy substitution in the leaves of both species from a busy traffic area.

AB  - This study is based on the results obtained from the experiments conducted within two Short Term
Science Missions (STSMs) in the Research Unit Environmental Simulation, Helmholtz Zentrum München
during 2011 and 2012. Our aim was to investigate the effects of realistic UV-B doses on photosynthesis
and secondary metabolism in variegated leaves. Variegated Plectranthus coleoides plants were exposed
to UV-B radiation (0.90 W m-2) under two photosynthetic active radiation (PAR) intensities (LL: 395 and
HL: 1350 μmol m-2 s-1) for nine days in the sun simulators at the Helmholtz Zentrum München. In the
green leaf portions, UV-B radiation stimulated photosynthetic rates in P. coleoides at both PAR
intensities and doubled the size of plastoglobuli whereas the contents of photosynthetic pigments were
slightly increased at HL. The concentrations of phenylpropanoids, catechins and hydroxybenzoic acids,
were preferentially accumulated in green leaf portions, independently on radiation regimes. A hallmark
of UV-B induced changes in plant metabolism, the induction of flavonoid pathway, was evidenced in P.
coleoides by accumulation of apigenin and cyanidin glycosides in the whole leaf at both background
PARs. UV-B induced accumulation of apigenin and cyanidin glycosides was more pronounced in the
white leaf portions, compared to green one. Moreover, we observed differential response of H2O2
scavenging system to high PAR and UV-B in relation to tissue type. Alteration of linear electron flow,
provoked by acclimation to UV-B at HL was associated with decreased ascorbate redox state and APX
activity. In summary, UV-B radiation stimulated CO2 assimilation and increased fixed carbon flow into
photosynthetic pigments, phenylpropanoids and flavonoids/anthocyanins which might be important for
photoprotection of photosynthetic machinery under high light intensity.

AB  - Phyllostachis bissetti was introduced to urban areas in Belgrade with the aim to improve the quality of air polluted by heavy traffic. Dust released from fuel combustion adsorbed on the leaves reaching up to 10% of leaf dry weight. Adsorbed dust was analyzed for its morphological structure, chemical content and prooxidant activity. SEM analysis of dust indicated the presence of particulate matter fractions PM10 and PM2.5. Determination of peroxidase levels (POD, EC 1.11.1.7), ascorbate concentration and total antioxidant capacity in the leaves showed that, overall, P. bissetii had high antioxidative potential to cope with oxidative stress under urban environmental conditions. Leaf protein and chlorophyll content accompanied by high growth rate of seedlings planted at different locations indicated excellent acclimatization capacity of P. bissetti to the heavily polluted urban areas.
