南方根结线虫是世界上危害最大的根结线虫之一，寄主范围广泛，几乎侵染所有植物。感染后，这种线虫会在根部诱导成瘤。我们已经发现，在暴露在光下的番茄根中，这些诱导的瘤变绿。这种胆汁变绿是光依赖的，并被生长素处理所抑制。在这些绿色瘤中检测到了叶绿素，在根结区也检测到了叶绿体。叶绿素a/b结合蛋白-4基因在虫胆中的表达上调。这些结果表明，光处理诱导了番茄植株叶绿体的发育。隐姓埋名的胆汁发育。
Meloidogyne incognitais one of the most detrimental root-knot nematode pests in the world because of its wide range of hosts, infecting almost all plant species. Following infection, this nematode induces gall formation in the root. We have found that these induced galls turn green in tomato roots exposed to light. This gall greening was light-dependent and inhibited by auxin treatment. Chlorophyll was detected in these green galls, and chloroplasts were also observed in the root-knot region. Expression of thechlorophyll a/b-binding protein-4gene was upregulated in the galls. These results indicate that light treatment induces chloroplast development in tomato plants infected withM. incognitaduring gall development.
