Plant-parasitic nematodes often interact with their host plants via chemical compounds for successful invasion. In cyst nematodes, hatching requires chemicals known as hatching factors that are released from host roots. Previous studies succeeded in identifying and synthesizing solanoeclepin A (SEA) as a host-derived hatching factor for Globodera rostochiensis (Wollenweber) Behrens and Globodera pallida (Stone) Behrens (Tylenchida: Heteroderidae). However, no published data were available about the hatching response of Globodera species, other than G. rostochiensis, toward SEA. In this study, we tested the hatching responses of G. rostochiensis, G. pallida, Globodera ellingtonae Handoo, Carta, Skantar, and Chitwood, Globodera tabacum (Lownsbery and Lownsbery) Behrens, and Globodera artemisiae (Eroshenko and Kasachenko) Behrens (Tylenchida: Heteroderidae) toward SEA by exposing eggs of each species to 0.001, 0.01, 0.1, 1, 10, and 100 ppb of SEA and observing their hatching response. SEA stimulated the hatching of Solanaceae-parasitic Globodera species (G. rostochiensis, G. pallida, G. ellingtonae, and G. tabacum). The optimal concentration of SEA for hatching was 0.01–10 ppb. However, the hatching activity of G. pallida and G. ellingtonae was lower than that of G. rostochiensis and G. tabacum. SEA showed no effects on G. artemisiae which is parasitic to Artemisiae plants.

solanoeclepin A对Globodera (Tylenchida: Heteroderidae)种卵的孵化刺激活性

植物寄生线虫通常通过化合物与其宿主植物相互作用以成功入侵。在胞囊线虫中，孵化需要从宿主根部释放的称为孵化因子的化学物质。以前的研究成功地鉴定和合成了茄属植物 A (SEA) 作为宿主衍生的 Globodera rostochiensis (Wollenweber) Behrens 和 Globodera pallida (Stone) Behrens (Tylenchida: Heteroderidae) 孵化因子。然而，除了 G. rostochiensis 之外，没有关于 Globodera 物种对 SEA 的孵化反应的已发表数据。在本研究中，我们测试了 G. rostochiensis、G. pallida、Globoodera ellingtonae Handoo、Carta、Skantar 和 Chitwood、Globoodera tabacum（Lownsbery 和 Lownsbery）Behrens 和 Globodera artemisiae（Eroshenko 和 Kasachenko） Behrens（Tylenchida Heteroderidae) 通过将每个物种的卵暴露于 0.001、0.01、0.1、1、10 和 100 ppb 的 SEA 并观察它们的孵化反应。SEA 刺激了茄科寄生球虫物种（G. rostochiensis、G. pallida、G. ellingtonae 和 G. tabacum）的孵化。用于孵化的最佳 SEA 浓度为 0.01–10 ppb。但G. pallida 和G. ellingtonae 的孵化活性低于G. rostochiensis 和G. tabacum。SEA 对寄生于蒿属植物的 G. artemisiae 没有显示出影响。用于孵化的最佳 SEA 浓度为 0.01–10 ppb。但G. pallida 和G. ellingtonae 的孵化活性低于G. rostochiensis 和G. tabacum。SEA 对寄生于蒿属植物的 G. artemisiae 没有显示出影响。用于孵化的最佳 SEA 浓度为 0.01–10 ppb。但G. pallida 和G. ellingtonae 的孵化活性低于G. rostochiensis 和G. tabacum。SEA 对寄生于蒿属植物的 G. artemisiae 没有显示出影响。
