Advances of research on rice senescence mutants

Plant senescence is a progress between mature and death, it is a necessary phase in plant lifecycle. Plant senescence characterized as degradation of biomacromolecule, dissociate of cell structures, reusability of nutrients and etc. Senescence is regulated by various factors. In this review, we focused on the description of rice senescence mutants based on brief summarization of the physiochemical properties during senescence and the factors influencing senescence in plant. Which may improve the understanding of the genetic regulation on rice senescence provide some references for studies on rice development and breeding new with delay senestence. (authors)
