Abstract
The invention discloses a major gene bHLH150 for controlling cold resistance of rice and application of the major gene bHLH150, and relates to the technical field of plant genetic engineering. The nucleotide sequence of the major gene bHLH150 for controlling cold resistance is shown as SEQ ID No: 1, after the gene is subjected to CRISPR / Cas9 editing mutation in rice, the cold resistance of a transgenic plant is remarkably reduced, and the transgenic plant becomes cold sensitive; the rice expressing or overexpressing the gene bHLH150 is high in survival rate at low temperature, and the cold resistance is improved. The cold-resistant major gene bHLH150 disclosed by the invention has important theoretical and practical significance on research on a rice cold-resistant regulation and control molecular mechanism and cultivation of a new rice cold-resistant variety. Wide application space and market prospects are realized in the agricultural field.
