病害是影响农作物生产的重要因素之一。由华中农业大学王石平教授领导的水稻抗病课题组以对水稻危害最大的细菌性病害——白叶枯病作为对象,长期致力于水稻抗病机理的研究。最近,该课题组在水稻抗病调控机理方面又取得了重要进展。这个课题组的前期研究发现,WRKY45是水稻抗病过程中重要的数量抗性位点;该位点存在两种不同的等 Disease is one of the important factors affecting crop production. The research group led by Professor Wang Shuping from Huazhong Agricultural University has long been committed to studying the disease resistance mechanism of rice against bacterial leaf blight, the most damaging bacterial disease in rice. Recently, the group has made important progress in the regulation of rice disease resistance. The previous study of this research group found that WRKY45 is an important quantitative resistance site in rice disease resistance; there are two different
