WebDongxiang Wild Rice (Oryza rufipogon) is the northernmost wild rice in the world known to date and has extremely high cold tolerance and many other adversity-resistant properties. To identify the genes responsible for the high stress tolerance, we isolated and characterized a basic helix-loop-helix (bHLH) protein gene OrbHLH001 from Dongxiang Wild Rice. WebOverexpression of OrbHLH001 enhanced the tolerance to freezing and salt stresses in transgenic Arabidopsis. Examination of the expression of cold-responsive genes in transgenic Arabidopsis showed that the function of OrbHLH001 differs from that of ICE1 and is independent of a CBF/DREB1 cold-response pathway.
