Interested in cloning, utilization and mechanism of genes related to agronomic traits, especially the abiotic stress-related genes in wild rice. Using introgression lines derived from wild rice, she has mapped and cloned several genes related to cold tolerance, salt tolerance, and other abiotic stresses in wild rice, providing excellent germplasm resources and theoretical references for rice stress-tolerant molecular breeding. Related research results have been published in journals such as Mol Plant, Plant Biotechnol J, and Plant J and so on. She has presided over 5 projects of the National Natural Science Foundation of China.
