Abstract
This invention discloses a major gene for controlling cold tolerance in rice. bHLH150 This invention relates to the field of plant genetic engineering technology, specifically the major gene for controlling cold tolerance. bHLH150 The nucleotide sequence is shown in SEQ ID No:1. After CRISPR / Cas9 editing mutations in rice, the transgenic plants exhibited significantly reduced cold tolerance and became cold-sensitive; while those expressing or overexpressing the gene... bHLH150 The rice exhibits a high survival rate at low temperatures, thus improving its cold resistance. This invention relates to the major cold-resistance gene. bHLH150 Research on the molecular mechanisms regulating cold tolerance in rice is of significant theoretical and practical importance for the breeding of new cold-tolerant rice varieties. It also has broad application prospects and a promising market outlook in the agricultural field.
