梨Pybbx24基因突变及其矮化功能的应用
By cloning the Pybbx24 gene from pear trees and overexpressing it in Arabidopsis thaliana and tobacco, we verified its function in promoting plant dwarfing, which solved the problem of insufficient gene resources for pear tree dwarfing breeding, achieved the effect of fruit tree dwarfing breeding, and reduced agricultural costs.

AI Technical Summary
The existing technology has limited understanding of the molecular mechanisms of pear tree dwarfing, and lacks effective genetic resources for fruit tree dwarfing breeding, resulting in high orchard management costs and difficulty in achieving high-density cultivation to increase yield.
The Pybbx24 gene, which is associated with dwarfing in pear trees and belongs to the B-Box family, was cloned and identified. By constructing a recombinant expression vector and overexpressing the gene in Arabidopsis thaliana and tobacco, its function of promoting plant dwarfing was verified.
It provides new genetic resources for dwarfing fruit tree breeding, reduces agricultural costs, achieves the effect of dwarfing plants, and provides the possibility of gene editing for high-density cultivation, thereby reducing orchard management costs.
