植物不定根再生与扦插生根相关激素调控研究进展OA

Plant adventitious root regeneration is a self-repair or replacement process of damaged structures by the plant body,usually occurring during tissue culture or cutting.During the cutting process,wound stimulation triggers a series of responses and signal transduction that regulates downstream factors,thereby inducing adventitious root formation.Plant hormones play a crucial regulatory role in the process of adventitious root formation.However,the survival rate of cuttings from certain woody plants is relatively low,and the molecular mechanisms by which plant hormones regulate the regeneration of adventitious roots remain unclear.This article reviewed the basic process of adventitious root regeneration in plant cuttings,explored the rules of wound activation signal transduction,and summarized the regulatory molecular mechanisms of hormones,transcription factors,and gene families involved in adventitious root development.It provided a reference for the study of the regeneration mechanism of woody plant cuttings.
