Sedentary plant endoparasitic nematodes can cause detrimental yield losses in crop plants making the study of detailed cellular, molecular, and whole plant responses to them a subject of importance. In response to invading nematodes and nematode-secreted effectors, plant susceptibility/resistance is mainly determined by the coordination of different signaling pathways including specific plant resistance genes or proteins, plant hormone synthesis and signaling pathways, as well as reactive oxygen signals that are generated in response to nematode attack. Crosstalk between various nematode resistance-related elements can be seen as an integrated signaling network regulated by transcription factors and small RNAs at the transcriptional, posttranscriptional, and/or translational levels. Ultimately, the outcome of this highly controlled signaling network determines the host plant susceptibility/resistance to nematodes.
固着内寄生植物线虫会给作物造成严重的产量损失，因此研究植物对线虫的详细细胞、分子和整体反应至关重要。植物对入侵线虫和线虫分泌的效应物的易感性/抗性主要取决于不同信号通路的协调，包括特定的植物抗性基因或蛋白、植物激素合成和信号通路，以及对线虫攻击产生的活性氧信号。各种与线虫抗性相关的元件之间的串扰可以看作是一个由转录因子和小 RNA 在转录、转录后和/或翻译水平调节的整合信号网络。最终，这个高度受控的信号网络的结果决定了宿主植物对线虫的易感性/抗性。
