Multiple copies of a novel amphipathic α-helix forming segment in Physcomitrella patens dehydrin play a key role in abiotic stress mitigation
Plants use a diverse set of proteins to mitigate various abiotic stresses. The intrinsically
disordered protein dehydrin is an important member of this repertoire of proteins,
characterized by a canonical amphipathic K-segment. It can also contain other stress-
mitigating noncanonical segments—a likely reflection of the extremely diverse nature of
abiotic stress encountered by plants. Among plants, the poikilohydric mosses have no inbuilt
mechanism to prevent desiccation and therefore are likely to contain unique noncanonical …
