The characteristics of expression of two genes, H1 and Gro1-4, which determine the resistance to the sedentary parasitic nematode Globodera rostochiensis (Wollenweber, 1923) Behrens, 1975, in the resistant (Krepysh) and susceptible (Nevskii) potato cultivars was studied under a short-term exposure to low temperatures. Such treatment of susceptible plants at the early stages of ontogeny led to the activation of expression of H1 and Gro1-4 genes in roots and the H1 gene in leaves. The transcriptional activity of R genes was detected not only in roots but also in leaves (i.e., in tissue remote from the site of direct injury by the nematode) in the case of both genetic and induced resistance, indicating the development of a systemic defense response of plants to infection.
研究了在短期低温暴露条件下，抗性（Krepysh）和易感（Nevskii）马铃薯品种中决定对定居性寄生线虫罗斯托克马铃薯金线虫（Wollenweber，1923年）Behrens，1975年抗性的两个基因H1和Gro1 - 4的表达特征。在个体发育早期对易感植物进行这种处理，导致根中H1和Gro1 - 4基因以及叶中H1基因的表达激活。在遗传抗性和诱导抗性的情况下，不仅在根中而且在叶中（即远离线虫直接损伤部位的组织中）都检测到了R基因的转录活性，这表明植物对感染产生了系统性防御反应。
