Recently, new progress has been made in the cloning and evolution of cold tolerance genes at the booting stage of rice completed by the Institute of Grain Making, Hubei Academy of Agricultural Sciences in cooperation with China Agricultural University and other units, and the research result article Stepwise selection of natural variations at CTB2 and CTB4a improves cold duration adaptation domestication of japonica rice was published online in full in New phytologist (IF: 8. 51). In this study, a new rice booting stage cold tolerance gene CTB2 was cloned, and the gradual selection of natural variants of CTB2 and CTB4a improved the cold adaptability of japonica rice. It was found that cold tolerance japonica rice originated in Kunming, Yunnan Province, China. Rice is a cold-sensitive crop originating from the tropics or subtropics, and encountering low temperatures during the booting stage can lead to the inability of rice to develop normally and severely reduce yield...
