Zhong J.L., and Fang J., 2024, Genetic regulation of diurnal flowering time divergence in rice: the role of the OsMYB8 and OsJAR1 module, Rice Genomics and Genetics, 15(1): 28-35 (doi: 10.5376/rgg.2024.15.0004)

On March 13, 2024, a joint research achievement by the State Key Laboratory for Conservation and Utilization of Subtropical Agro-Bioresources, School of Life Sciences, South China Agricultural University, the Guangdong Provincial Key Laboratory of New Technology in Rice Breeding, Rice Research Institute of Guangdong Academy of Agricultural Sciences, and the Life Sciences Technology Center of China National Seed Group Co., Ltd. was published in Nature Communications. The paper, titled "Natural variation in OsMYB8 confers diurnal floret opening time divergence between indica and japonica subspecies," had Yajun Gou and Yueqing Heng as co-first authors, with Rongxin Shen and Haiyang Wang as co-corresponding authors. The study was funded by the National Natural Science Foundation of China Innovation Group Project and the Hainan Yazhou Bay Seed Laboratory Commander Project, among others. It identified the OsMYB8 gene as a key factor regulating the divergence in diurnal flowering time in rice. The interaction between OsMYB8 and OsJAR1 significantly affects the flowering time of indica and japonica rice. Transferring the indica allele of OsMYB8 into japonica rice effectively advances flowering time, providing a new strategy for indica-japonica hybrid breeding.
