The impact of the GRAS [gibberellic acid-insensitive (GAI), repressor of GA1-3 mutant (RGA), and scarecrow (SCR)] family on plant development and the potential to resist environmental stress needs much emphasis.<h4>Objectives</h4>This study aims to investigate the evolution, expansion, and adaptive mechanisms of <i>GRASs</i> of important representative plants during polyploidization.<h4>Methods</h4>We explored the evolutionary characteristics of <i>GRASs</i> in 15 representative plant species by systematic biological analysis of the genome, transcriptome, metabolite, protein complex map and phenotype.<h4>Results</h4>The GRAS family was systematically Journal of advanced research191-205https://www.ebi.ac.uk/biostudies/studies/S-EPMC8020295biostudies-literatureA multilayered cross-species analysis of GRAS transcription factors uncovered their functional networks in plant adaptation to the environment.PMC8020295Li JLi CLiu MYu GSun WWang XWang YfalseA multilayered cross-species analysis of GRAS transcription factors uncovered their functional networks in plant adaptation to the environment.<h4>Introduction</h4>Environmental stress is both a major force of natural selection and a prime factor affecting crop qualities and yields.
