초록
Three key genetic loci required for proper progression of leaf senescence were identified in Arabidopsis thaliana. Mutations in these loci cause delay in all senescence symptoms examined, including both anabolic and catabolic activities, during natural senescence and upon artificial senescence induced by various senescence-inducing treatments. The result provides a decisive evidence that leaf senescence is a genetically programmed phenomenon controlled by several monogenic loci in Arabidopsis thaliana. The result further indicates that leaf senescence caused by various senescence signals occurs, at least in part, through common pathways in Arabidopsis and that the threed genetic loci function at the common steps.
