{"cited_by_count":206736,"description":"This cluster of papers focuses on the phylogeny, evolution, and classification of grasses (Poaceae), with particular emphasis on topics such as apomixis, C4 photosynthesis, reproductive pathways, genetics, and the evolutionary history of bamboos. It explores the genetic control of apomixis, geographical parthenogenesis, polyploidy, and the molecular phylogeny of various grass subfamilies.","display_name":"Plant Taxonomy and Phylogenetics","domain_id":"1","external_ids":{"openalex":"https://openalex.org/T12568","wikipedia":"https://en.wikipedia.org/wiki/Poaceae"},"field_id":"11","id":"T12568","keywords":[{"display_name":"Poaceae","id":"poaceae","score":0.6716,"url":"https://openalex.org/keywords/poaceae"},{"display_name":"Festuca","id":"festuca","score":0.7217,"url":"https://openalex.org/keywords/festuca"},{"display_name":"wild wheat relative","id":"wheat-wild-relative","score":0.2732,"url":"https://openalex.org/keywords/wheat-wild-relative"},{"display_name":"grass taxonomy","id":"grass-taxonomy","score":0.856,"url":"https://openalex.org/keywords/grass-taxonomy"},{"display_name":"Poa pratensis","id":"poa-pratensis","score":0.2943,"url":"https://openalex.org/keywords/poa-pratensis"},{"display_name":"tufted hairgrass","id":"tufted-hairgrass","score":0.6496,"url":"https://openalex.org/keywords/tufted-hairgrass"},{"display_name":"timothy grass","id":"phleum-pratense","score":0.3006,"url":"https://openalex.org/keywords/phleum-pratense"},{"display_name":"Agrostis capillaris","id":"common-bent-grass","score":0.5805,"url":"https://openalex.org/keywords/common-bent-grass"},{"display_name":"Calamagrostis epigejos","id":"calamagrostis-epigejos","score":0.7277,"url":"https://openalex.org/keywords/calamagrostis-epigejos"},{"display_name":"Alopecurus","id":"alopecurus","score":0.8926,"url":"https://openalex.org/keywords/alopecurus"},{"display_name":"Elymus repens","id":"couch-grass","score":0.4232,"url":"https://openalex.org/keywords/couch-grass"},{"display_name":"cheatgrass","id":"bromus-tectorum","score":0.3461,"url":"https://openalex.org/keywords/bromus-tectorum"},{"display_name":"Agrostis","id":"agrostis","score":0.6686,"url":"https://openalex.org/keywords/agrostis"},{"display_name":"creeping bentgrass","id":"agrostis-stolonifera","score":0.3915,"url":"https://openalex.org/keywords/agrostis-stolonifera"},{"display_name":"Bromus","id":"bromus","score":0.52,"url":"https://openalex.org/keywords/bromus"},{"display_name":"Echinochloa crus-galli","id":"barnyard-grass","score":0.2401,"url":"https://openalex.org/keywords/barnyard-grass"},{"display_name":"Poa bulbosa","id":"poa-bulbosa","score":0.8211,"url":"https://openalex.org/keywords/poa-bulbosa"},{"display_name":"wood bluegrass","id":"poa-nemoralis","score":0.8562,"url":"https://openalex.org/keywords/poa-nemoralis"},{"display_name":"Poa trivialis","id":"poa-trivialis","score":0.5869,"url":"https://openalex.org/keywords/poa-trivialis"},{"display_name":"Aegilops","id":"aegilops","score":0.4734,"url":"https://openalex.org/keywords/aegilops"},{"display_name":"giant tussock","id":"giant-tussock-grass","score":0.7754,"url":"https://openalex.org/keywords/giant-tussock-grass"},{"display_name":"orchid hybrid","id":"orchid-hybrid","score":0.2241,"url":"https://openalex.org/keywords/orchid-hybrid"},{"display_name":"Aristida","id":"aristida","score":0.7786,"url":"https://openalex.org/keywords/aristida"},{"display_name":"Bromus hordeaceus","id":"bromus-hordeaceus","score":0.7963,"url":"https://openalex.org/keywords/bromus-hordeaceus"},{"display_name":"dog's-tail grass","id":"cynosurus-cristatus","score":0.7593,"url":"https://openalex.org/keywords/cynosurus-cristatus"}],"legacy_keywords":["Phylogeny","Grasses","Apomixis","C4 Photosynthesis","Evolution","Classification","Genetics","Reproductive Pathways","Bamboos","Polyploidy"],"openalex_id":"https://openalex.org/T12568","source_created_date":"2024-01-23T15:27:14","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1105","url":"/topics/T12568","works_api_url":"https://api.openalex.org/works?filter=topics.id:T12568","works_count":291721,"label":"Plant Taxonomy and Phylogenetics","provider":"openalex","revision":"4ffeb92caaf36fa3","taxonomy_revision":"f050b5d4780b1289","title":"Plant Taxonomy and Phylogenetics","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"38285029306834983","address_version":"morton4x16-v1","coordinates":[1,11,1105,12568],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
