3.承担的主要项目Major projects undertaken
National High-Tech Research and Development Program of China (863 Program)
National Natural Science Foundation of China
National Science and technology support program from Ministry of science and technology of China
Special Fund for Agro-scientific Research in the Public Interest from Ministry of Agriculture of China
Major scientific and technological project from Government of Shaanxi Province
Scientific and technological project in Shaanxi Province.
The physiology and ecology of garlic second growth and it's mechanism were probed and the demonstration and integration of matching technology of new cultivars; The key technology research and demonstration of Chinese chive, Chinese Cabbage and line pepper pollution-free production in western area were systematically evaluated, and the vernalization characteristics of garlic and it's growth and development were also probed; Garlic germplasm resources were collected and polyploid and high disease resistance germplasms were innovated through somaclonal mutant selection. Changes in volatile content of cucumber fruits as well as associated gene expression and enzyme activity in developing cucumber fruits were investigated; The molecular mechanism of lipoxygenas and hydroperoxidelyase which involved in the synthesis of aldehydes; The members of glutaredoxins which involved in the flower sex differentiation and defense mechanism to necrotrophic fungus; The alleviation effects and mechanismof grafting to root-knot nematode of cucumber were studied; The genes underlying important phenotypes of cucumber were identified and validated; Interaction molecular mechanism between cucumber and Pseudoperonospora cubensis were explored.
We have published in total more than 200 academic papers including more than 40 SCI papers. We got 3 “Second prize of Shaanxi province Scientific and technological progress in 2004, 2006, 2009 respectively. We have awarded 4 national patents and 2 new cultivars were approved.
