The responses of a collection of Arabidopsis thaliana ecotypes to mechanical inoculation with turnip mosaic potyvirus were assessed. The virus induced characteristic severe symptoms of infection in systemically infected plants. Resistance was found in four ecotypes: Bay-0, Di-0, Er-0, and Or-0. Enzyme-linked immunosorbent assay results of the resistant ecotypes suggested that ecotypes Di-0, Er-0, and Or-0 actually consist of mixed genotypes with resistances acting at different levels in the virus life cycle. Another form of resistance was found in ecotype Bay-0, for which several lines of evidence indicated an interference with viral cell-to-cell movement in the inoculated leaves.
评估了一批拟南芥生态型对芜菁花叶马铃薯Y病毒机械接种的反应。该病毒在系统感染的植物中引发了典型的严重感染症状。在四种生态型中发现了抗性:Bay-0、Di-0、Er-0和Or-0。抗性生态型的酶联免疫吸附测定结果表明,Di-0、Er-0和Or-0生态型实际上由混合基因型组成,其抗性在病毒生命周期中作用于不同水平。在Bay-0生态型中发现了另一种抗性形式,有几条证据表明它对接种叶片中的病毒细胞间运动有干扰作用。
