| 1 | Phylotranscriptomic insights into Asteraceae diversity,polyploidy,and morphological innovation显示文摘Biodiversity is not evenly distributed among relatedgroups,raising questions about the factors con-tributing to such disparities.The sunflower family(Asteraceae,>26,000 species)is among the largestand most diverse plant families,but its species di-versity is concentrated in a few subfamilies,pro-viding an opportunity to study the factors affectingbiodiversity.Phylotranscriptomic analyses here of244 transcriptomes and genomes produced a phy-logeny with strong support for the monophyly ofAsteraceae and the monophyly of most subfamiliesand tribes.This phylogeny provides a reference fordetecting changes in diversification rates and pos-sible factors affecting Asteraceae diversity,whichinclude global climate shifts,whole‐genome dupli-cations(WGDs),and morphological evolution.Theorigin of Asteraceae was estimated at~83 Mya,with most subfamilies having diverged before theCretaceous–Paleocene boundary.Phylotran-scriptomic analyses supported the existence of 41WGDs in Asteraceae.Changes to herbaceousnessand capitulescence with multipleflower‐like capitula,often with distinctflorets and scaly pappus/re-ceptacular bracts,are associated with multiple up-shifts in diversification rate.WGDs might have con-tributed to the survival of early Asteraceae byproviding new genetic materials to support mor-phological transitions.The resulting competitive ad-vantage for adapting to different niches would haveincreased biodiversity in Asteraceae. | Caifei Zhang Chien‐Hsun Huang Mian Liu YiHu Jose L.Panero Federico Luebert Tiangang Gao Hong Ma | 2021 | Journal of Integrative Plant Biology2021，63，7： | 4 |
