Mutated genes
Alias	SID
Organism	Fescue (Festuca pratensis Huds.)
Description	Sid locus (sgr), a mutant allele of which is responsible for the stay green character, encodes or regulates the gene for, phaeophorbide a dioxygenase.Alleles of F. pratensis and rice homologs of Arabidopsis At4g22920 likely underlie the monocot stay-green phenotypes.In addition, At4g22920 is the most similar Arabidopsis protein to LOC_Os09g36200. F. pratensis-derived homologue of LOC_Os09g36200 was considered to be a strong candidate for y (sgr).
