  To determine the genomic structure of a potato virus Y (PVY) isolate from Yulin, China and its phylogenetic relationship with reported PVY strains.The complete genome of the PVY ShX14 was amplified and sequenced from overlapping fragments using 11 pairs of primers designed from the conserved regions of the known PVY isolates.Genomic structure and recombination events of the isolate were evaluated by various bioinformatics approaches.Phylogenetic tree was reconstructed by Maximum Likelihood method (ML) using nucleotide sequences of coding regions.In addition, phylogeny-trait association analysis was used to evaluate the relationship between PVY isolate and known stains reported.The results show that the complete sequence of ShX14 has 9, 724 nucleotides, excluding the 3-terminal poly (A) tail.

由致病疫霉菌引发的马铃薯晚疫病是严重为害马铃薯安全生产的卵菌病害.致病疫霉菌基因组编码数以百计,序列高度分化的RXLR效应因子.病菌侵染过程中RXLR效应因子可抑制寄主防卫反应,使植物感病;RXLR效应因子也可被植物抗病蛋白识别,诱导过敏性坏死反应.针对不同分离菌株中RXLR效应因子的表达特征和多态性分析,有助于深入认识致病疫霉菌致病机理.我们通过SSR分子标记对采自8个省份的3 000多个致病疫

马铃薯晚疫病是由致病疫霉菌(Phytophthora infestans)引起的一种毁灭性病害,在世界各主产区均有发生.抗性品种是控制马铃薯晚疫病最经济、有效和环保的方法,但由于致病疫霉的易变性可快速进化特点、品种抗病性容易损失,而抗性基因的时空分布是决定致病疫霉进化的关键因子.在本研究中,我们从具有不同群体遗传多样性的马铃薯寄主群体采集150株致病疫霉,分别接种在感病品种费乌瑞它(Favorit
