植物在地上和地下同时遭受多次攻击。在实验室中，通常以个体为基础研究害虫和/或病原体攻击。植物对多种生物攻击的分子反应以及不同防御途径之间的相互作用尚不清楚。马铃薯(Solanum tuberosum L.)通过对寄主植物的分析，研究了一种寄生的寄生线虫(Globodera Pallida)和一种吸食韧皮部的食草动物(Myzus Persicae)之间的植物间接相互作用。在预先感染梅毒的马铃薯植株上，桃疫霉菌的繁殖成功率高于对照植株。马铃薯叶片中的水杨酸(SA)在线虫和蚜虫单独侵染后系统地增加，SA介导的标记基因的表达也相应增加。当植物与线虫混合感染时，与蚜虫感染相关的茉莉酸的增加被抑制。我们的数据表明，在一种寄生线虫和一种吸液昆虫之间存在着积极的、不对称的相互作用。马铃薯植株在感染灰霉病菌后的系统反应间接影响烟粉病菌的表现。这项工作揭示了控制单个作物病虫害的额外次要好处。
Plants suffer multiple, simultaneous assaults from above and below ground. In the laboratory, pests and/or pathogen attack are commonly studied on an individual basis. The molecular response of the plant to attack from multiple organisms and the interaction of different defense pathways is unclear. The inducible systemic responses of the potato (Solanum tuberosum L.) host plant were analyzed to characterize the plant-mediated indirect interactions between a sedentary, endoparasitic nematode (Globodera pallida), and a phloem-sucking herbivore (Myzus persicae). The reproductive success of M. persicae was greater on potato plants pre-infected with G. pallida compared to control plants. Salicylic acid (SA) increased systemically in the leaves of potato plants following nematode and aphid infection singly with a corresponding increase in expression of SA-mediated marker genes. An increase in jasmonic acid associated with aphid infection was suppressed when plants were co-infected with nematodes. Our data suggests a positive, asymmetric interaction between a sedentary endoparasitic nematode and a sap-sucking insect. The systemic response of the potato plant following infection with G. pallida indirectly influences the performance of M. persicae. This work reveals additional secondary benefits of controlling individual crop pests.
