The stay-green gene (SGR) is a key regulatory factor for chlorophyll degradation and senescence. However, to date, little is known about SGR in Zoysia japonica. In this study, ZjSGR was cloned, using rapid amplification of cDNA ends-polymerase chain reaction (PCR). The target sequence is 831 bp in length, corresponding to 276 amino acids. Protein BLAST results showed that ZjSGR belongs to the stay-green superfamily. A phylogenetic analysis implied that ZjSGR is most closely related to ZmSGR1.
