Aim Figs (Ficus, Moraceae) are exploited by rich communities of often host‐specific phytophagous wasps. Among them, gall‐inducing Sycophaginae (Hymenoptera, Chalcidoidea) may share a common history with Ficus and their mutualistic pollinators (Agaonidae). We investigate here, for the first time, the phylogeny and biogeographical history of Sycophaginae and compare the timing of radiation and dispersion of major clades with available data on Ficus and fig pollinators. Reconstructing the history of their host colonization and association over space and time is central to understanding how fig wasp communities were assembled. Location World‐wide. Methods Maximum likelihood and Bayesian analyses were conducted on 4267 bp of mitochondrial and nuclear DNA to produce a phylogeny of all genera of Sycophaginae. Two relaxed clock methods with or without rate autocorrelation were used for date estimation. Analyses of ancestral area were also conducted to investigate the geographical origin of the Sycophaginae. Results The phylogeny is well resolved and supported. Our data suggest a post‐Gondwanan origin for the Sycophaginae (50–40 Ma) and two independent out‐of‐Australia dispersal events to continental Asia. Given palaeoclimatic and palaeogeographic records, the following scenario appears the most likely. The ancestor of Idarnes+Apocryptophagus migrated to Greater India through the Ninetyeast Ridge (40–30 Ma). The ancestor of Anidarnes+Conidarnes dispersed later via Sundaland (25–20 Ma). Idarnes and Anidarnes subsequently reached the New World via the North Atlantic land bridges during the Late Oligocene Warming Event. Apocryptophagus reached Africa c. 20 Ma via the Arabic corridors and returned to Australasia following the expansion of Sundaland tropical forests (20–10 Ma). Main conclusions Sycophaginae probably invaded the fig microcosm in Australia c. 50–40 Ma after the origin of their host plant. Once associated with figs, they dispersed out of Australia and radiated together with their host fig and associated pollinator through the tropics. We recorded a good coincidence of timing between dispersal events of Sycophaginae and continental connections. Furthermore, fruit pigeons that disperse figs probably spread out of Australasia through the Indian Ocean via the Ninetyeast Ridge c. 38 Ma. Therefore, our study highlights the potential for combining molecular phylogenetics with multiple methods of dating of interacting groups to reconstruct the historical biogeography of plant–herbivore associations. 相似文献

A total of 56 morphological characters were analyzed for 53 cirrospiline species that represent all of the 17 described genera of the tribe. The other taxa of the Eulophinae included in the analysis were six species of six representative genera in the tribe Eulophini, a species of Elasmus (the only genus comprising the tribe Elasmini), and a species of Trichospilus (unplaced). Trichospilus and two of the six genera of Eulophini examined were placed within Cirrospilini. Monophyly of Cirrospilini (when these two genera of Eulophini and Trichospilus are included) and of the cirrospiline genera for which more than one species were examined was supported, but the relationships between the genera were poorly resolved. An exception was Cirrospilus, the largest genus in the Cirrospilini, monophyly of which was not supported to any extent. 相似文献

We identified rice genes that might be involved in drought stress tolerance by virtue of their anti-apoptotic activity. Potential anti-apoptosis related genes were identified by screening an Oryza sativa cDNA library derived from drought stressed tissues in a yeast functional assay. About 28 O. sativa cDNAs promoted yeast survival following engagement of Bax-induced apoptosis. An O. sativa cDNA encoding R12H780 was a highly conserved putative senescence-associated-protein (OsSAP). OsSAP was both highly and rapidly expressed in response to drought stress. Additionally, OsSAP was found to be localized to the mitochondria. Overall, OsSAP represents a new type of Bax suppressor related gene and endows multiple stress tolerance in yeast. 相似文献

Two new species in the cryptic chrysidid wasp subfamily Loboscelidiinae are described based on males from Gunung Halimun National Park, West Java, Indonesia. One is the second species in Rhadinoscelidia Kimsey, and the other, belonging in Loboscelidia Westwood, is the first species of the genus for the Indonesian fauna. 相似文献
