Convergent evolution of desiccation tolerance in grasses
Plant Science Research WeeklyMany bryophytes and other non-seed plants are tolerant to vegetative desiccation, which is thought to have been necessary for colonization of land. By contrast, most seed plants lack this capacity, although they retain desiccation tolerance in their pollen and seeds. However, some seed plants, known…
PIMT and ABI-TFs cascade mediates desiccation tolerance and longevity in rice seeds (Development)
Plant Science Research WeeklyThe ABA INSENSITIVE (ABI) transcription factors (TFs) (ABI3, ABI4, ABI5) regulate DT and play essential roles during seed germination. Therefore, these TFs must be functionally protected during seed desiccation. Recalcitrant seeds are sensitive to desiccation, while orthodox seeds possess a remarkable…
Oxidant system and ABA drive germination in seeds of palm species with differences in desiccation tolerance ($) (Seed Sci Res)
Plant Science Research WeeklyPalms are a taxonomically and ecologically diverse group. This wide variety is also reflected in their seeds, with their species showing all combinations of dormancy and desiccation tolerance behaviors. Yet, comparative studies of their germination physiology are relatively scarce. In this paper, Santos…
