OsRacD is a critical molecular switch involved in photoperiod fertility conversion of photoperiod sensitive genic male sterile rice. Taking OsRacD as bait, a new rice myosin heavy chain partial cDNA was isolated from the rice panicle by yeast two-hybrid,and designated OsMY1.In this study, the interaction between OsMY1 and OsRacD had been testified by yeast two-hybrid and pull down assay, the results showed that OsMY1 could bind with OsRacD, Our study suggested that OsMY1 maybe the target of OsRacD. The results also provided important evidence for further study on the functional relationship between OsMY1 and OsRacD in vivo.
