Abstract Potato cyst nematodes (PCN), Globodera pallida and G. rostochiensis are sedentary endoparasites that cause great yield losses in potato crops and are currently considered a serious economic threat. Both species are A2 quarantine pests for the European and Mediterranean Plant Protection Organization. PCN control is difficult because of their biology, long survival in the absence of their hosts and the measures available being insufficient and limited due to restrictions on the use of chemical pesticides. During the nematode life cycle and after infection by the second-stage juveniles, a feeding structure is formed, the syncytium, which allows further nematode development. Solanum sisymbriifolium is a non-tuber plant from the Solanaceae family, that is resistant to PCN and used as a trap crop. Second-stage juveniles penetrate S. sisymbriifolium roots and establish the syncytium, but further nematode development is inhibited. Thus, understanding the molecular basis under S. sisymbriifolium mechanism of resistance is important and will contribute to developing new PCN control strategies. Some of the known molecular mechanisms of PCN infection, plant defense and molecular resistance mechanisms are explored in this review.

马铃薯胞囊线虫：解决老问题的新方法

摘要 马铃薯胞囊线虫 (PCN)、苍白球虫和 G. rostochiensis 是久坐的内寄生虫，会导致马铃薯作物的产量损失巨大，目前被认为是严重的经济威胁。这两个物种都是欧洲和地中海植物保护组织的 A2 检疫性有害生物。由于多氯化萘的生物学特性、在没有宿主的情况下长期存活以及由于化学杀虫剂的使用受到限制，可用的措施不足和有限，因此控制多氯萘是困难的。在线虫生命周期中和被第二阶段幼虫感染后，形成了一种摄食结构，即合胞体，它允许线虫进一步发育。Solanum sisymbriifolium 是茄科的一种非块茎植物，对 PCN 具有抗性，可用作诱捕作物。第二阶段的少年渗透 S. sisymbriifolium 根并建立合胞体，但进一步的线虫发育受到抑制。因此，了解 S. sisymbriifolium 抗性机制下的分子基础很重要，并将有助于开发新的 PCN 控制策略。本综述探讨了一些已知的 PCN 感染分子机制、植物防御和分子抗性机制。
