STAY-GREEN (SGR) genes are key regulatory factors involved in senescence and ripening process in plant green organs. Based on phylogenetic analysis,STAY-GREEN genes were divided into two groups,SGR andSGR-LIKE (SGRL) subfamilies. However, there are some differences betweenSGR andSGRL in sequence features, expression patterns and functional characters among different plant species, while the functions for SGR/SGRL homolog genes are not the same. In this article, we summarize the research progress inSGR/SGRL genes in recent years including the chromosome location, classiifcation and expression, and possible functions ofSGR/SGRL genes.
