The AWA neurons of mainly perceive volatile attractive odors, while the ASH neurons perceive pH, penetration, nociception, odor tropism, etc. The perceptual neurons of have been little studied. The number of infestations around and within tomato roots was significantly reduced after RNA interference for high-homology genes in AWA and ASH neurons compared between and Through in situ hybridization, we further determined the expression and localization of the homologous genes and in . In this study, we found that has neuronal sensing pathways similar to AWA and ASH perception of for sensing chemical signals from tomato roots. Silencing the homologous genes in these pathways could affect the nematode perception and infestation of tomato root systems. The results contribute to elucidating the process of the plant host perception of .
主要的AWA神经元主要感知挥发性引诱气味，而ASH神经元感知pH值、穿透力、伤害感受、气味趋向性等。[具体物种]的感知神经元研究较少。与[对比对象]相比，对AWA和ASH神经元中的高同源基因进行RNA干扰后，番茄根周围和根内的侵染数量显著减少。通过原位杂交，我们进一步确定了同源基因[具体基因名称1]和[具体基因名称2]在[具体物种]中的表达和定位。在本研究中，我们发现[具体物种]具有类似于AWA和ASH对[具体内容]感知的神经元传感途径，用于感知来自番茄根的化学信号。沉默这些途径中的同源基因会影响线虫对番茄根系的感知和侵染。这些结果有助于阐明植物宿主对[具体内容]的感知过程。
