Pepper Pseudomonas syringae pathovar syringae (Pss) comparative genomics

Pseudomonas syringae pv. syringae (Pss) is an emerging phytopathogen that causes Pseudomonas leaf spot (PLS) disease in pepper plants. Pss can cause serious economic damage to pepper production, yet very little is known about the virulence factors associated with disease in pepper seedlings. We investigated differences in virulence of Pss isolates through whole genome sequence analysis (functional genomics and non-synonymous single nucleotide variations).丁香假单胞菌丁香致病变种（Pseudomonas syringae pv. syringae，Pss）是一类新兴植物病原菌，可引发辣椒植株感染假单胞菌叶斑病（Pseudomonas leaf spot，PLS）。该病原菌会对辣椒生产造成严重经济损失，但目前学界对与辣椒幼苗发病相关的致病因子仍所知甚少。本研究通过全基因组序列分析（包括功能基因组学与非同义单核苷酸变异分析），探究了不同Pss分离株的致病力差异。
