    Water-saving and Drought-resistance Rice R&D
    We work at water-saving and drought-resistance (WDR) breeding and water saving and high yield cultivation. By combining the use of modern molecular breeding techniques and conventional breeding methods, we breed new varieties of rice that have the characteristics of both resistance to insect, high nutrition efficiency, high yield and quality, and water saving and drought resistance. Currently, the main target area of breeding includes the Yangtze River basin, the Huang-huai-hai region and Southeast Asia region. We also study the water saving and high yield cultivation technology of WDR, especially focusing on reducing pesticide and fertilizer use and improving water use efficiency under different agro-ecological conditions and farming methods such as paddy field and dry land. Our goal is to increase rice production on middle-low yielding farmland.

    1. 水稻抗逆性遺傳研究

    Research on Abiotic Stress Resistance in Rice
    We study the genetic mechanism under the resistance to abiotic stress in rice, with high priority on drought and low soil nutrients (N and P). Both artificial segregation populations like recombinant inbred lines (RILs) or introgression lines (ILs) and natural populations like core collection of rice germplasm are used to conduct whole genome linkage or association mapping. Meanwhile, integrated analysis of profiles of genes, proteins and metabolites is conducted to understand the regulation network for drought resistance. Promising lines has been developed via pyramiding breeding procedure and effective selection under both drought and low nitrogen conditions.

    Genetic Research on Drought Resistance and Sheath Blight Resistance in Rice
    We study the genetic basis of drought avoidance in rice. Combining the linkage analysis and association study by using mapping populations, such as RILs, DH lines, introgression lines and core collection, we try to find that what kind of root morphological characterizations are related to water absorption from deep soil, which genes regulate the root morphogenesis, which genes control stomatal closure uder dehydration stress. For the research on sheath blight resistance in rice, we use mulptiple genetic methods and different mapping populations to elucidate the molecular genetic basis. Introgression lines are used to screen and develop new sheath blight resistant rice germplasm.

    Research on Gene Regulation Biology in Rice
    Our research interests are gene regulation biology of water-saving and drought-resistant rice and germplasm biology. The primary research objectives exist in identification and cloning of drought-stress responsive or/and water-saving and drought-resistant functional and regulationary genes, non-coding miRNAs as well as in clarifying the roles of these genes and uncovering the molecular mechanism of the above stated genes. Meanwhile, we also do some research on cryopreservation of plant germplasm and production protocol and environmental evaluation of a new farming system of using drip irrigation for growing water-saving and drought-resistant rice (WDR).

    Research on Drought Resistant Germplasm and Gene Function in Rice
    Our researches focus on the drought resistance identification and evaluation in rice germplasm and genetic populations with specialized screening facility. And on that basis, linkage and association analysis were used to discover the molecular basis of rice drought resistance. Meanwhile, the drought resistant genes were mined by analysis of gene profiles and the gene function were elucidated by transgenic and biochemical approaches.

    Research on Gene Function of Drought Resistance in Rice
    We use reverse genetic methods, such as screening genomic polymorphism, analysis of transcriptome and identification of mutants, to clone beneficial genes among rice drought resistant resources. Gene function and molecular mechanism of drought resistance will be investigated. Application of those genes in rice genetic engineering breeding will be evaluated.
