Wild Rice Resources and Rice Variety Improvement Team

Research Interests

Common wild rice is an important natural resource in Guangxi and an important gene treasure for rice breeding. Our research interests: (1) We focus on the conservation and utilization of common wild rice originated in Guangxi. More than 1,800 wild rice resources are conserved in our germplasm repository; (2) Screening of the resistance genetic germplasms (including abiotic stress and biological stress resistance, such as cold tolerance, drought tolerance, saline-alkali resistance, bacterial stripe disease resistance, etc.) from common wild rice resources, and cloning the resistance genes by map-based cloning and genome-wide association analysis (GWAS); (3) Functional dissection of the molecular functions of the resistance genes; (4) Breeding abiotic/biotic resistant rice varieties using the resistance genes to solve the yield loss problem caused by the current varieties with weak abiotic/biotic resistance cultivated in South China.

Principal Investigator: Prof. Jijing Luo (pH.D.)

Professor Jijing Luo, as team leader of Wild Rice Resources and Rice Variety Improvement, has made a noteworthy academic achievement and published more than 30 papers in journals such as Nature Genetics, Molecular Plant, Plant Cell, and Journal of Experimental Botany, among others.
