The short and intricate life of the suspensor.

摘要: The suspensor is a short-lived tissue critical for proper embryonic development in many higher plants. While the was initially thought to simply suspend embryo endosperm, it has been found through decades of research that serves multiple important purposes. be vital patterning and numerous studies have undertaken into complex transcriptional cross-talk between proper. Indeed, mutants also display abnormalities embryo. suspensor's role as nutrient conduit shown using ultrastructural histochemical techniques. Biochemical approaches centre early hormone production several species. frequently used model programmed cell death shows signs termination almost immediately upon developing. This review covers essential functions throughout its short existence from disciplines including structural, genetic biochemical perspectives.
