Abstract In this study, we identified proteins in cotton associated with resistance to bacterial blight (BB) by using two-dimensional electrophoresis (2-DE). To search for proteins that may trigger resistance/defense response, here we analyzed Gossypium hirsutum plants at 24 and 120 hours after inoculation with Xanthomonas campestris pv. malvacearum (Xcm). Photosynthesis-related proteins showed pronounced reduction in the Xcm-inoculated plants. These results indicate that the resistance response in cotton involves the reduction of protein abundance to cope with infection caused by Xcm and support our previous studies showing that the negative regulation of photosynthesis is crucial for resistance to allow an active defense response.

蛋白质组学筛选，用于鉴定与油菜黄单胞菌抗性有关的蛋白质。棉花中的锦葵

摘要 在本研究中，我们使用二维电泳 (2-DE) 鉴定了棉花中与抗白叶枯病 (BB) 相关的蛋白质。为了寻找可能引发抗性/防御反应的蛋白质，我们在这里分析了在接种野油菜黄单胞菌后 24 和 120 小时的陆地棉植物。锦葵属（Xcm）。光合作用相关蛋白在 Xcm 接种的植物中表现出明显的减少。这些结果表明棉花的抗性反应涉及蛋白质丰度的降低以应对 Xcm 引起的感染，并支持我们之前的研究表明光合作用的负调节对于抗性至关重要，从而允许积极的防御反应。
