中文摘要：许多具有农业重要性的由介体传播的植物病毒是通过刺吸式口器昆虫在植物间进行传播的。到目前为止，人们对于介体介导的向寄主植物水平传播以及向昆虫后代垂直传播的机制都了解甚少。在水平传播过程中，持续传播的病毒通过利用完整的病毒体或病毒诱导的包含物克服中肠和唾液腺屏障。卵黄蛋白原或共生细菌利用的现有卵母细胞进入通道可介导雌虫垂直传播病毒。作者假设病毒也可能通过附着在精子表面上而被雄性昆虫垂直传播。在不利于水平传播的越冬季节中通过昆虫介体抑制病毒的垂直传播可以为病毒控制开辟新的途径。
外文摘要：Many vector-borne plant viruses of agricultural importance are persistently transmitted from plant to plant by sap-sucking insects. So far, the mechanisms for vector-mediated horizontal transmission of the viruses to plant hosts and for vertical transmission to insect offspring have been poorly understood. During horizontal transmission, intact virions or virus-induced inclusions are exploited by persistently transmitted viruses to overcome the midgut and salivary gland barriers. The existing oocyte entry paths used by vitellogenin or symbiont bacteria can mediate the vertical transmission of viruses by female insects. We hypothesize that the viruses may also be vertically transmitted by male insects via attachment to the surface of sperm. Inhibiting vertical transmission of the viruses by insect vectors in the overwintering season unfavorable for horizontal transmission may open new perspectives for viral control.
