Plant hormone-mediated regulation of plant height in Brassica napus L.OA
Plant height(PH),a critical agronomic trait in Brassica napus L.,directly influences yield potential,canopy structure,and lodging resistance.An appropriate PH not only enhances lodging resistance but also improves the efficiency of light energy utilization.Although substantial progress has been achieved through quantitative trait locus(QTL)mapping,Genome-wide association studies(GWAS),and molecular studies,the regulatory network and key determinants underlying PH in B.napus remain insufficiently understood.This review summarizes the molecular mechanisms by which major phytohormones,namely auxins(IAA),gibberellins(GAs),brassinosteroids(BRs),and strigolactones(SLs),regulate PH by modulating cell elongation,division,and internode differentiation.By integrating hormone-mediated pathways,this review provides a theoretical framework for elucidating the molecular basis of PH regulation and offers guidance for breeding high-yield,lodging-resistant rapeseed varieties.
