MADS-box Genes Driven Life History Strategy Diversity in Brassicaceae
The numerous flowering genes that have been identified in different plants play a crucial role in determining whether a plant is annual or perennial.However,the evolutionary mechanism by which these flowering genes drive the transition between annual and perennial life history strategies in Brassicaceae plants remains poorly understood.A recent study focused on natural variations in different genera of Brassicaceae.They identified three closely related MADS-box transcription factor genes,namely FLC,FLM,and MAF,and elucidated their molecular mechanisms associated with the transition between annual and perennial behavior.Their findings suggest that the life-history strategy in Brassicaceae plants(i.e.,the conversion between perennial,biennial,and annual behavior)is a continuum determined by the dosage of FLC-like MADS-box genes.The study elucidates the evolutionary mechanisms and trajectories underlying the reciprocal conversion of life history strategies from annual to perennial in Brassicaceae,providing a theoretical foundation for breeding perennial rapeseed varieties and offering insights for Brassicaceae crops improved towards perennial grain.
