A nuclear phylogenomic tree of grasses (Poaceae) recovers current classification despite gene tree incongruence 2024 Access copy available to the general public Unrestricted Summary Grasses (Poaceae) comprise c. 11 800 species and are central to human livelihoods and terrestrial ecosystems. Knowing their relationships and evolutionary history is key to comparative research and crop breeding. Advances in genome-scale sequencing allow for increased breadth and depth of phylogenomic analyses, making it possible to infer a new reference species tree of the family. We inferred a comprehensive species tree of grasses by combining new and published sequences for 331 nuclear genes from genome, transcriptome, target enrichment and shotgun data. Our 1153-tip tree covers 79% of grass genera (including 21 genera sequenced for the first time) and all but two small tribes. We compared it to a newly inferred 910-tip plastome tree. We recovered most of the tribes and subfamilies previously established, despite pervasive incongruence among nuclear gene trees. The early diversification of the PACMAD clade could represent a hard polytomy. Gene tree–species tree reconciliation suggests that reticulation events occurred repeatedly. Nuclear–plastome incongruence is rare, with very few cases of supported conflict. We provide a robust framework for the grass tree of life to support research on grass evolution, including modes of reticulation, and genetic diversity for sustainable agriculture. info:eu-repo/grantAgreement/ES/DGA/LMP82-21 info:eu-repo/grantAgreement/EC/H2020/101105838/EU/Mutualism abandonment in land plants and the origin of novel adaptations/SYMBIOLOSS This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 101105838-SYMBIOLOSS info:eu-repo/grantAgreement/ES/MICINN/PID2022-140074NB-I00 info:eu-repo/grantAgreement/EUR/MICINN/TED2021-131073B-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 8.1 2024 PLANT SCIENCES 12 / 273 = 0.044 2024 Q1 T1 3.293 2024 Plant Science 2024 Q1 Physiology 2024 Q1 17.5 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hackel, Jan Vorontsova, Maria S.
