Molecular genetics of leaf senescence in Arabidopsis

Trends Plant Sci. 2003 Jun;8(6):272-8. doi: 10.1016/S1360-1385(03)00103-1.


Leaf senescence is a developmentally programmed degeneration process that constitutes the final step of leaf development and is controlled by multiple developmental and environmental signals. In addition to the information obtained from other plants, Arabidopsis has, as a model system, contributed to our understanding of this complex phenomenon in molecular genetic terms. Recent discoveries have identified several genetic mutants and potential regulatory components in Arabidopsis. Identifying further mutants that exploit novel biological resources, screening Scheme and a global functional analysis of senescence-associated genes in Arabidopsis should increase our understanding of the complex regulatory networks.
