Title: Yanfang Li: Innovator in Rice Planthopper Resistance
Introduction
Yanfang Li is a prominent inventor based in Guangdong, China. She has made significant contributions to agricultural science, particularly in the field of plant protection. Her work focuses on enhancing rice varieties to resist pests, thereby improving crop yields and sustainability.
Latest Patents
Yanfang Li holds a patent for the rice planthopper-sensitivity gene BGIOSGA015651 and its applications. This gene plays a crucial role in regulating rice planthopper resistance. Through her research on rice varieties BG1222 and TN1, she discovered that the expression level of BGIOSGA015651 in insect-resistant varieties differs significantly from that in insect-susceptible varieties. By utilizing molecular breeding or genetic engineering methods, the expression of this gene can be reduced or knocked out, allowing insect-susceptible plants to gain high insect resistance. The resistance level of the TN1 variety improves dramatically from level 9 to levels 0-1 after the gene is knocked out. This innovation has substantial economic and ecological benefits, making it a valuable asset for rice cultivation.
Career Highlights
Yanfang Li is affiliated with the Plant Protection Research Institute at the Guangdong Academy of Agricultural Sciences. Her research has been pivotal in advancing the understanding of pest resistance in rice, contributing to food security and agricultural sustainability.
