{"cited_by_count":3367604,"description":"This cluster of papers explores the evolution of plant genomes, with a focus on polyploidy, transposable elements, small RNAs, and the role of repetitive elements. It investigates the impact of genome duplication on genetic diversity, speciation, and epigenetic regulation, shedding light on the evolutionary significance of these processes in plants.","display_name":"Chromosomal and Genetic Variations","domain_id":"1","external_ids":{"openalex":"https://openalex.org/T10434","wikipedia":"https://en.wikipedia.org/wiki/Polyploidy"},"field_id":"11","id":"T10434","keywords":[{"display_name":"chromosome number","id":"chromosome-number","score":0.5795,"url":"https://openalex.org/keywords/chromosome-number"},{"display_name":"karyotype","id":"karyotype","score":0.4196,"url":"https://openalex.org/keywords/karyotype"},{"display_name":"polyploidy","id":"polyploidy","score":0.4165,"url":"https://openalex.org/keywords/polyploidy"},{"display_name":"transposable elements","id":"transposable-elements","score":0.4425,"url":"https://openalex.org/keywords/transposable-elements"},{"display_name":"karyotype evolution","id":"chromosome-evolution","score":0.6838,"url":"https://openalex.org/keywords/chromosome-evolution"},{"display_name":"meiosis","id":"meiosis","score":0.2594,"url":"https://openalex.org/keywords/meiosis"},{"display_name":"genome evolution","id":"genome-evolution","score":0.4316,"url":"https://openalex.org/keywords/genome-evolution"},{"display_name":"cytogenetics","id":"cytogenetics","score":0.2338,"url":"https://openalex.org/keywords/cytogenetics"},{"display_name":"repetitive DNA","id":"repetitive-dna","score":0.418,"url":"https://openalex.org/keywords/repetitive-dna"},{"display_name":"karyology","id":"karyology","score":0.2929,"url":"https://openalex.org/keywords/karyology"},{"display_name":"heterochromatin","id":"heterochromatin","score":0.2955,"url":"https://openalex.org/keywords/heterochromatin"},{"display_name":"chromosome pairing","id":"chromosome-pairing","score":0.5542,"url":"https://openalex.org/keywords/chromosome-pairing"},{"display_name":"genome size","id":"genome-size","score":0.3889,"url":"https://openalex.org/keywords/genome-size"},{"display_name":"retrotransposons","id":"retrotransposons","score":0.5621,"url":"https://openalex.org/keywords/retrotransposons"},{"display_name":"nucleolar organizer regions","id":"nucleolar-organizer-regions","score":0.5079,"url":"https://openalex.org/keywords/nucleolar-organizer-regions"},{"display_name":"whole-genome duplication","id":"whole-genome-doubling","score":0.3942,"url":"https://openalex.org/keywords/whole-genome-doubling"},{"display_name":"chromosome morphology","id":"chromosome-morphology","score":0.7191,"url":"https://openalex.org/keywords/chromosome-morphology"},{"display_name":"plant cytogenetics","id":"plant-cytogenetics","score":0.7265,"url":"https://openalex.org/keywords/plant-cytogenetics"},{"display_name":"chromosomal rearrangements","id":"chromosomal-rearrangements","score":0.218,"url":"https://openalex.org/keywords/chromosomal-rearrangements"},{"display_name":"sex chromosomes","id":"sex-chromosomes","score":0.2464,"url":"https://openalex.org/keywords/sex-chromosomes"},{"display_name":"chromosome banding","id":"chromosome-banding","score":0.4316,"url":"https://openalex.org/keywords/chromosome-banding"},{"display_name":"B chromosomes","id":"b-chromosomes","score":0.7518,"url":"https://openalex.org/keywords/b-chromosomes"},{"display_name":"satellite DNA","id":"satellite-dna","score":0.6072,"url":"https://openalex.org/keywords/satellite-dna"},{"display_name":"centromere","id":"centromere","score":0.2992,"url":"https://openalex.org/keywords/centromere"},{"display_name":"C-banding","id":"c-banding","score":0.6878,"url":"https://openalex.org/keywords/c-banding"}],"legacy_keywords":["Genome Evolution","Polyploidy","Transposable Elements","Plant Speciation","Small RNAs","Centromeres","Genetic Diversity","Chromosome Duplication","Epigenetic Regulation","Repetitive Elements"],"openalex_id":"https://openalex.org/T10434","source_created_date":"2024-01-23T15:27:06","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1110","url":"/topics/T10434","works_api_url":"https://api.openalex.org/works?filter=topics.id:T10434","works_count":169508,"label":"Chromosomal and Genetic Variations","provider":"openalex","revision":"9aa4ceec60447ab3","taxonomy_revision":"f050b5d4780b1289","title":"Chromosomal and Genetic Variations","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36173934902912227","address_version":"morton4x16-v1","coordinates":[1,11,1110,10434],"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}
