AB  - The adaptability of halophytes to increased soil salinity is related to complex rhizosphere interactions. In this study, an integrative approach, combining culture-independent and culture-dependent techniques was used to analyze the bacterial communities in the endorizosphere of indigenous succulent halophytes Salicornia europaea, Suaeda maritima, and Camphorosma annua from the natural salt marshes of Slano Kopovo (Serbia). The 16 S rDNA analyses gave, for the first time, an insight into the composition of the endophytic bacterial communities of S. maritima and C. annua. We have found that the composition of endophyte microbiomes in the same habitat is to some extent influenced by plant species. A cultivable portion of the halophyte microbiota was tested at different NaCl concentrations for the set of plant growth promoting (PGP) traits. Through the mining of indigenous halotolerant endophytes, we obtained a collection representing a core endophyte microbiome conferring desirable PGP traits. The majority (65%) of the selected strains belonged to the common halotolerant/halophilic genera Halomonas, Kushneria, and Halobacillus, with representatives exhibiting multiple PGP traits, and retaining beneficial traits in conditions of the increased salinity. The results suggest that the root endosphere of halophytes is a valuable source of PGP bacteria supporting plant growth and fitness in salt-affected soils.

AB  - soil salinity has numerous negative effects on plant growth and poses
a significant threat to agricultural productivity worldwide. The diversity of
endophytic bacterial communities found in various indigenous halophytes
such as Salicornia europaea, Suaeda maritima, and Camphorosma annua, may
reveal beneficial bacteria with various plant growthpromoting (PGP) properties.
Members of Halomonas, the largest genus of the family Halomonadaceae,
are rod-shaped, gram-negative, moderately halophilic bacteria that have been
increasingly isolated from various saline environments, including halophyte
tissues. As part of the halophytic microbiota, halotolerant plant growth-promoting
endophytic bacteria can contribute to plant host growth, productivity, and
fitness under abiotic and biotic stresses. The use of halotolerant PGP bacteria
represents a good alternative strategy to mitigate the effects of salt stress in
crops and to recover saline soils. The aim of this study was to isolate halotolerant
bacteria from halophyte roots, and evaluate their PGP ability and their effect on
germination parameters of selected crops. The endophytic bacterial communities
in the roots of halophytes from natural saline soil in Slano Kopovo (Serbia)
were analyzed using culture-dependent techniques. The genus Halomonas was
the predominant among the halotolerant root-associated bacteria of analyzed
halophytes. We have isolated seven Halomonas sp. strains, six of which were
closely related (>99,86% similarity) to Halomonas songnenensis, a moderately
halophilic bacterium from saline and alkaline soils. Obtained isolates were tested
at different sodium chloride concentrations for a range of PGP traits at
different concentrations of sodium chloride. The selected strains were used to
inoculate seeds iand monitor of the germination process of barley, sunflower,
and wheat under conditions of elevated salinity. Most of the isolates tolerate
the NaCl concentration up to 18% and showed multiple PGP features with some
of them retained even in the presence of additional salt concentrations. The
germination test results showed that Halomonas seed inoculation positively
affected barley germination parameters in conditions with and without added
salt. The observed traits can be further exploited to improve plant growth and
augment the salt tolerance of agricultural production on saline soils.
