AI Technical Summary
The underlying mechanisms of dwarfing pear trees are poorly understood in current technologies, and there is a lack of effective genetic resources and methods to achieve dwarfing cultivation of fruit trees.
The PcBBX24C544T gene from 'Red Pear' was isolated and cloned. This gene lost its C-terminal domain due to a single-base mutation. Overexpression of this gene resulted in a dwarfing phenotype in the plant. The gene overexpression was achieved by constructing a recombinant expression vector and genetically engineered bacteria.
It provides new genetic resources for dwarfing fruit tree breeding, reduces agricultural costs, enables high-density cultivation, meets consumer demand, and stably obtains dwarf plants through Agrobacterium-mediated genetic transformation.
