Desiccation tolerance in the streptophyte green alga Klebsormidium: The role of phytohormones

摘要

The origin of phytohormones has been a puzzling question for decades; however, with the availability of large transcriptomic and genomic datasets of the early branching streptophytic green alga Klebsormidium this question can be addressed from a fresh perspective. Klebsormidium has recently been examined extensively for physiological and structural reactions to desiccation or cold temperatures,natural factors in soil crust living algae. Ecological influences have been made responsible for fine scaled structuring of genotypes and differentiation of cryptic species.But how do these organisms sense their changing environments?
