在早期的研究中，我们证明了植物与植物之间的相互作用是由被叶螨（Tetranychus urticae）侵染的利马豆叶子释放的挥发物介导的（Nature 406 (2000a) 512，Biochem. Biophys. Res. Commun. 277 (2000b) 305）。在本研究中，我们进一步表明，在实验室条件下，受二斑叶螨侵染的利马豆植物释放的挥发物激活了完整邻近植物叶子中编码发病机制相关蛋白和苯丙氨酸解氨酶的基因的转录。这一发现表明完整的利马豆植物可能对挥发性信号有反应。此外，由于绿色植物响应食草动物造成的机械损伤而释放绿叶挥发物（GLV），我们研究了 GLV 在植物与植物相互作用中的可能参与。我们发现(Z)-3-己烯醇、(E)-2-己烯醛和(Z)-3-己烯基乙酸酯诱导未受感染的叶子中防御基因的表达。这一发现表明 GLV 可能在植物与植物相互作用中充当信号化合物。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
In an earlier study, we demonstrated plant-plant interactions mediated by volatiles released from lima bean leaves infested by spider mites (Tetranychus urticae) (Nature 406 (2000a) 512, Biochem. Biophys. Res. Commun. 277 (2000b) 305). In the present study, we further show that, under laboratory conditions, volatiles emitted from T. urticae-infested lima bean plants activate transcription of genes encoding pathogenesis-related proteins and phenylalanine ammonia-lyase in leaves of intact neighboring plants. This finding indicates that intact lima bean plants may be responsive to volatile signals. Further, as green leaf volatiles (GLVs) are released from green plants in response to mechanical damage caused by herbivores, we studied possible involvement of GLVs in plant-plant interaction. We found that (Z)-3-hexenol, (E)-2-hexenal, and (Z)-3-hexenyl acetate, induced the expression of defense genes in uninfested leaves. This finding suggests that GLVs may act as signal compounds in plant-plant interactions. (C) 2001 Elsevier Science Ltd. All rights reserved.
