Gray leaf spot (GLS), caused by the fungal pathogen Cercospora, is one of the most serious foliar diseases of maize worldwide.Genetic diversity of 29 isolates of Cercospora, which isolated from different geographic regions in China, were analyzed by ISSR.In this study, a total of the 81 bands were amplified using 10 pairs of primers.The length of these bands ranged from 200 ~ 2000 bp and all of them were polymorphic.At similar level of 0.19, all isolates were clustered into two distinct groups.Strains isolated from maize collected from southwest and northeast clustering into different groups,indicated relatively abundant genetic diversity of Cercospora in China.ISSR analysis revealed the phylogenetic relationship and genetic differentiation of the isolates of Cercospora tested in this study.

非线性光学晶体材料在激光领域具有十分重要的作用,是高新技术的关键材料之一。当前商业化的中红外波段非线性光学晶体材料存在一个显著的缺点——激光损伤阈值较低,这使得它们的应用范围受到了一定的限制。因此,探索具有较高激光损伤阈值的新型中红外非线性光学晶体材料是目前非线性光学材料领域的重点和难点之一。本工作的研究目标是探索具有较高激光损伤阈值的新型中红外非线性光学晶体材料,研究的对象是以Hg为中心原子的卤
