摘　　要：榕属植物与其传粉小蜂组成了高度专一的专性共生关系(榕-蜂共生系统),如此高度紧密的互作关系被认为是驱动两者多样化的关键因素。榕-蜂共生系统主要依靠化学通讯完成相互识别,但目前仍不清楚化学通讯是如何维系现有共生关系并促进物种形成的。结合已有研究,系统梳理了榕-蜂共生系统化学通讯的基础与两者特异性识别的机制,阐述化学通讯在物种和种群层次对维持这一专性传粉关系的重要贡献,进而探讨化学通讯如何在协同成种和宿主转移成种两种模式中介导物种形成。最后,结合生理与多组学等技术展望榕-蜂共生系统的未来研究方向,为深入解析植物与昆虫协同进化的机制以及全球变化下物种的潜在响应模式提供重要参考。Ficus species(figs)and their pollinating wasps(fig wasps)comprise obligate mutualisms with high specificity,and such tight interspecific interactions are widely considered as a key driving factor for the diversification in both mutualists.Host identification of fig wasps predominantly relies on chemical communications,but it is still unclear how chemical communications stabilize fig-fig wasp mutualisms and facilitate co-diversification.Here,we reviewed the relevant studies to summarize the basis of chemical communications between figs and fig wasps and the mechanisms underlying the specific host identification.We then elucidated the crucial contribution of chemical communications to the maintenance of fig-fig wasp mutualisms at both species and population levels,with further discussion on how chemical communications mediated speciation through co-speciation and speciation by host-shifts of fig wasps.Finally,we addressed the necessity of combining physiological and multi-omics technologies in future research on fig-fig wasp mutualisms,which offered expectations for revealing coevolutionary mechanisms in other plant-insect interactions and their potential responses to the ongoing global changes.
