Abstract
The application belongs to the field of plant genetic engineering, and particularly relates to a sugar signal perception kinase LcTOR and application thereof in regulation and control of litchi fruit shedding. The gene codes a sugar signal perception kinase, expression of the gene is significantly up-regulated in the litchi fruit shedding process, treatment by an inhibitor AZD8055 can significantly reduce fruit shedding, and an activator MHY1485 promotes shedding, and heterologous overexpression of the gene can accelerate flower organ shedding of Arabidopsis thaliana, and silencing of the gene inhibits litchi fruit shedding. The application provides a new gene resource and regulation and control means for litchi and fruit shedding control of other crops.
