摘要： The abounding variations in wild rice provided potential reservoirs of beneficial genes for rice breeding. Maintaining stable and high yields under environmental stresses is a long-standing goal of rice breeding but is challenging due to internal trade-off mechanisms. Here, we report wild rice GL12W improves grain length and salt tolerance in both indica and japonica genetic backgrounds. GL12W alters cell length by regulating grain size related genes including GS2, and positively regulates the salt tolerance related genes, such as NAC5, NCED3, under salt stresses. We find that a G/T variation in GL12 promoter determined its binding to coactivator GIF1 and transcription factor WRKY53. GIF1 promotes GL12W expression in young panicle and WRKY53 represses GL12W expression under salt stresses. The G/T variation also contributes to the divergence of indica and japonica subspecies. Our results provide useful resources for modern rice breeding and shed insights for understanding yield and salt tolerance trade-off mechanism. Maintaining yield under environmental stresses is a long-standing but challenging goal of rice breeding. Here, the authors report a MYB transcription factor encoding gene GL12 from wild rice can improve grain length and salt tolerance in cultivated rice and the identification of its upstream regulators GIF1 and WRKY53.
