Patent ID: 11708395

Abstract:
A gene LBA5 for regulating lateral shoot angles, growth habits, and a plant architecture of Arachis hypogaea L., and use thereof are provided. In the present disclosure, a major gene LBA5 for controlling lateral shoot angles, growth habits, and a plant architecture of Arachis hypogaea L. is mapped and cloned from Arachis hypogaea L., which includes two homologous genes LBA5b and LBA5a and promoters thereof. The allelic variations of the gene can be selected through crossbreeding and backcrossing to achieve the genetic improvement on an angle between an Arachis hypogaea L. lateral shoot and a main stem. Through a genetic engineering operation for the gene and a change for a promoter sequence of the gene, the function or expression level of this gene in a procumbent Arachis hypogaea L. variety can be adjusted to further regulate an angle between an Arachis hypogaea L. lateral shoot and a main stem.
