AB  - Resurrection plant Ramonda serbica Panc. survives long desiccation periods
and fully recovers metabolic functions already one day upon watering. This study
aimed to investigate the role of soluble sugars and polyphenols, as well as cell wallassociated
polysaccharides and lignin in desiccation tolerance in R. serbica, an
endemic species from the Balkan peninsula. We combined differential
transcriptomics and proteomics, the analysis of soluble polyphenolics and sugars, as
well as FTIR analysis of the cell wall polymers. Pectin, cellulose, hemicellulose, and
xyloglucans were identified as polysaccharide components of the R. serbica cell
wall and they decreased upon desiccation. Desiccation provoked cell wall
remodelling related to the possible production of H2O2/HO via germin-like proteins
and pectin demethylesterification. In addition, desiccation induced carbon recycling
from starch to soluble sugar osmolytes, whose content significantly increased in
desiccated leaves. These data support the importance of specific sugars and the
plasticity of the cell wall as one of the major contributors to desiccation tolerance of
resurrection species, contributing to further crop drought tolerance improvement.
