Abstract

The invention belongs to the technical field of biotechnology and genetic engineering, and provides a gene LBA5 for regulating the side branch angle, growth habit and plant type of peanut and its application. A gene for controlling the side branch angle, growth habit and plant type of peanut is located and cloned. The main effect gene LBA5, which includes two homologous genes LBA5b and LBA5a and their promoters; the selection of the allelic variation of the gene through hybridization and backcrossing can realize the genetic improvement of the angle between the side branch and the main stem of peanut; By carrying out genetic engineering operations on the gene and changing the promoter sequence of the gene, the function or expression level of the gene in creeping peanuts can be adjusted to adjust the angle between the side branches and the main stem of peanuts; therefore, the two genes of LBA5 The two homologous genes LBA5b and LBA5a and their promoters can be used in the genetic improvement and genetic engineering improvement of side branch angle, growth habit and plant type of peanut and even other crops.

Description

Technical field:

[0001] The invention belongs to the fields of plant biotechnology and plant genetic engineering, and relates to a plant type gene LBA5 for regulating the side branch angle and growth habit of peanuts and its application. The gene LBA5 and its homologous genes are used to perform biotechnology on the plant type of peanuts and other crops. Improvement or genetic improvement. Background technique:

[0002] The growth angle of the side branches of the plant determines the plant shape of the whole plant. For most plants, the side branches are generally non-vertical, which is convenient for the group to obtain more resources such as sunlight and air. The genetic control of lateral branch angle has been well studied in model plants (Roychoudhry and Kepinski 2015). Early on, it has been studied to separate the gravitropic set-point angle (GSA) from the gravitropic growth zone (Digby and Firn 1995). The (dorsal) gravitropic determination of side branch angle is reg...
