OsGRF6-OsYUCCA1/OsWRKY82 Signaling Cascade Upgrade Grain Yield and Bacterial Blight Resistance in Rice.

ABSTRACT: As a major crop in the world, the sustainable development of rice is often severely restricted by bacterial blight. Breeding crops with resistance is an efficient way to control bacterial blight. However, enhancing resistance often incurs a fitness penalty, making it challenging to simultaneously increase bacterial blight resistance and yield potential. In this study, it is found that OsGRF6, besides being a high-yield gene, can significantly improve rice bacterial blight resistance. Compared with wild-type, the lesion lengths of transgenic material overexpressing OsGRF6 are significantly reduced after inoculation with Xanthomonas oryzae pv. oryzae (Xoo). Furthermore, OsGRF6 can directly bind to the promoters of OsYUCCA1 and OsWRKY82, upregulating their transcription and thereby increasing
