abstract = "The resurrection plant Ramonda serbica Panc. survives long desiccation periods and fully
recovers metabolic functions within one day upon watering. We aimed to identify key
candidates and pathways involved in desiccation tolerance in R. serbica by employing a
systems biology approach, combining transcriptomics and proteomics.
A total of 68,694 differentially expressed genes (DEGs; p-value<0.005 and abs(log2FC)≥2) were
obtained in R. serbica leaves upon desiccation. Among them, 23,935 and 26,169 genes were
upregulated and downregulated in desiccated leaves (DL) and hydrated leaves (HL), respectively.
By differential TMT-based proteomic analysis 1192 different protein groups were identified
after filtering with at least two unique peptides per protein. In total, 229 protein groups
were more abundant in HL and 179 in DL (p-value<0.05 and abs(FC)≥1.3). The majority
of the DAPs and DEGs involved in photosynthesis, transport, secondary metabolism, and
signaling, were less abundant in DL. On the other hand, proteins and transcripts associated
with fermentation, N-metabolism, heme, protein synthesis, folding and assembly, C1-
metabolism, and late embryogenesis abundant proteins, were more accumulated in DL.
A poor correlation between proteomic and transcriptomic results was detected for mitochondrial
electron transport and ATP production, gluconeogenesis, glycolysis, tricarboxylic
acid cycle, and enzymatic H2O2 scavengers due to different mRNA half-life, protein turnover,
dynamic posttranscriptional and posttranslational modifications. Finally, desiccation tolerance
in R. serbica is a species-specific process orchestrated by several metabolic pathways
that are temporally and compartmentally regulated at several levels.",
