Roles of stay-green (SGR) homologs during chlorophyll degradation in green plants
Abstract Chlorophyll (Chl) degradation is one of the most obvious signs of leaf senescence and fruit ripening.Stay-green (SGR) homologs that Stroller Book can remove magnesium from Chl a are the most important components in Chl degradation pathway in green plants.SGR homologs are not only universally involved in Chl breakdown during the senescence
