NON-YELLOWING2 (NYE2), a Close Paralog of NYE1, Plays a Positive Role in Chlorophyll Degradation in Arabidopsis
Dear Editor,Plant senescence is an integral part of plant development,with old organs senescing in association with the emergence and development of nascent ones.Rapid chlorophyll (Chl) degradation,the most prominent event during green organ senescence,is proposed to be a key detoxification process to facilitate massive nutrient remobilization (Lim et al.,2007).Biochemistry of Chl degradation has been extensively elucidated,but its regulation remains largely unknown.A significant step in the elucidation of Chl degradation regulation is the identification of NONYELLOWING1/STAY-GREEN1 (NYE1/SGR1) gene in diverse species,which is responsible for the green cotyledon trait of Mendel”s pea (for a review,see H(o)rtensteiner,2009).NYE1-related proteins (paralogs) are highly conserved,and there are one to three family members in most plant species,which can be divided into the SGR/NYE subfamily and the SGR-like (SGRL) subfamily (H(o)rtensteiner,2009).
