PhGRL2 Protein, Interacting with PhACO1, Is Involved in Flower Senescence in the Petunia
Dear Editor,The pathways of ethylene biosynthesis and signaling have been studied in detail (Ji and Guo,2013).Arabidopsis REVERSION-TO-ETHYLENE SENSITIVITY1 (RTE1),interacting with ETR1,and its homologs tomato GREEN RIPE (SIGR) and SIGRL1,and rice OsRTH1 negatively regulate the ethylene signaling (Barry and Giovannoni,2006;Resnick et al.,2006;Dong et al.,2010;Zhang et al.,2012).A newly published study suggested that a cytochrome b5 and RTE1 are functional partners in promoting ETR1-mediated repression of ethylene signaling in Arabidopsis (Chang et al.,2014).However,AtRTH,RTE1 homolog in Arabidopsis,and its closest homolog in the tomato,SIGRL2 (GR-like2),do not play a role in ethylene signaling (Dong et al.,2010),and the function of the homologs of these members is not well known.
