AB  - Ramonda serbica Panc. is a resurrection plant species that can survive desiccation for a long
period and fully resume metabolic functions upon rewatering in a very short period, even within
48 h. The goal of this study was to identify key candidates and pathways involved in desiccation tolerance in R. serbica. To achieve this, systems biology approach combining transcriptomics,
proteomics, and analysis of specific metabolites was employed. In addition, FTIR analysis of the
cell wall polymers and a detailed analysis of the photosynthetic electron transport (PET) chain
were performed. In total, 1192 different protein groups were quantified by TMT-based comparative quantitative proteomics. Among them, 408 protein groups showed a statistically significant
difference in abundance between hydrated (HL) and desiccated leaves (DL). Upon desiccation, the
majority of proteins related to photosynthetic processes were less abundant, while chlorophyll
fluorescence measurements implied shifting from linear photosynthetic transport (PET) to cyclic
electron transport (CET). The amounts of H2O2 scavenging enzymes, including ascorbate-glutathione cycle components, catalases, peroxiredoxins, Fe-, and Mn- superoxide dismutase (SOD) were
reduced in DL. However, four Cu/ZnSOD isoforms, three polyphenol oxidases, six germin-like proteins (GLPs), and 22 late embryogenesis abundant proteins (LEAPs; mainly LEA4 and dehydrins),
were desiccation-inducible. Desiccation-induced cell wall remodelling by changes in cell wall
polymer composition might be linked with pectin demethylesterification and GLP-derived H2O2/
HO•. Our study demonstrated that desiccation tolerance in R. serbica is a complex, species-specific process orchestrated by several metabolic pathways and regulatory networks acting at the transcript, protein, metabolite and physiological levels.

AB  - Resurrection plant Ramonda serbica Panc. survives desiccation for a long period and fully recovers metabolic functions already within one day upon watering [1]. Besides osmotic stress, desiccation provokes the accelerated generation of reactive oxygen species. The aim of our study was obtaining more insight into the mechanisms of desiccation tolerance in R. serbica by TMT labelled comparative quantitative proteomics of hydrated (HL) and desiccated leaves (DL). After de novo transcriptome analysis, 189456 transcripts with 189003 unigenes were annotated with seven common databases. Proteomic analysis allowed for the relative quantification of 895 different protein groups, 321 with a statistically significant difference in abundance between FL and DL. Among them, 25% referred to chloroplast and almost the same percentage were associated with desiccation and oxidative stress. Almost all differentially abundant proteins related to photosynthetic processes were down-regulated in DL, while those required for protein translation were more abundant in HL. Within differentially abundant proteins involved in antioxidative defence, the levels of enzymes involved in ascorbate-glutathione cycle, peroxiredoxins, Fe and Mn superoxide dismutase (SOD) were all reduced in DL, while germin-like proteins, three Cu/Zn SOD isoforms and polyphenol oxidases were more abundant in DL compared with HL. The protein family with the highest number of members showing the greatest accumulation upon desiccation comprised twenty different late embryogenesis abundant proteins (LEAPs), similarly as found by differential transcriptomic analysis. Taken together, our results imply a key role of LEAPs and Cu/Zn SOD in protective mechanism against desiccation in R. serbica, that may have significant implications on drought-related studies of crops grown in arid areas. This work was supported by the Science Fund of the Republic of Serbia (PROMIS project LEAPSyn-SCI, grant number 6039663). M.V. wishes to acknowledge the support of COST Action BM1405 for approving STSM in Padua during 2017 and 2018.
