Desiccation tolerance in bryophytes: perspectives from early career scientists

Desiccation tolerance in bryophytes: perspectives from early career scientists.

Desiccation tolerance (DT, also “desiccation tolerant”) is a complex trait that evolved early in land plants and was pivotal to the colonization of the terrestrial environment in this clade. Expressing this trait allows the plant body to revive from an air-dried condition. Among embryophytes, the bryophytes are unique in that a majority of bryophyte species express this trait in vegetative tissues, i.e., have the capacity to be DT in their photosynthetic tissues. Less than 1% of other embryophytic species of plants express this trait vegetatively, and a case can be made that perhaps all bryophytes (~18,000 species) express this trait to some degree. This symposium proposes a forum on the subject by scientists actively working in the discipline and who are yet in the early phases of their careers. These scientists include graduate students, postdoctoral scholars, and early career professionals. These individuals are immersed in performing creative experiments on DT in a variety of plants and settings, including but not limited to Sphagnum, Physcomitrella, desert bryophytes, aquatic bryophytes, and sperm biology. Their interests include the ecology of DT, rehydration dynamics of DT, hardening and dehardening dynamics of DT, biological crusts and the carbon cycle, transcriptomics of the desiccation/hydration cycle, and moss sperm DT. This symposium should assist these scientists in launching their careers in this exciting area, giving each increased visibility to the scientific community, and give them an opportunity to present their recent findings to an international audience.
