| 1 | The EST Analysis of A Suppressive Subtraction cDNA Library of Chinese Wild Vitis pseudoreticulata Inoculated with Uncinula necator显示文摘Uncinula necator is a worldwide serious fungus disease causing annual heavy lost on grapevine production. In order to get more informations on defense related EST sequences and help breeding program, we constructed and characterized a suppression subtractive hybridization cDNA library with artificially inoculated leaves and control Chinese wild Vitis pseudoreticulata clone Baihe-35-1, which is highly resistant to powdery mildew. In the library, the length of 58 EST fragments known as putative functions varied from 130 to 800 bp, and 60% of the ESTs exhibited high similarity to known sequences in database of GenBank with BLASTX analysis. These genes were involved in stress/defense response, detoxification, signal transduction, disease defense, and etc., and 14 ESTs remained unknown or hypothetical proteins, which may be new genes. The experiment provided an important basis for studying the disease-resistance mechanism and obtaining the genes for the aim of improving grapevine powdery mildew resistance. | SHI Jiang-li, WANG Yue-jin, ZHU Zi-guo and ZHANG Chao-hong Key Laboratory of Horticultural Plant Germplasm Utilization in Northwest China, Ministry of Agriculture/Shaanxi Key Laboratory of Molecular Biology for Agriculture/College of Horticulture, Northwest A&F University, Yangling 712100, P.R.China | 2010 | Agricultural Sciences in China2010，9，2： | 5 |
