The plant growth hormone auxin has an important role in a variety of plant growth and developmental processes. Identification of transcription factors, some with defined genetic function, has shed new light on the mechanisms of auxin regulated gene expression. In addition, the molecular characterization of genes required for auxin response indicates that regulated protein degradation by the ubiquitin-proteosome pathway has an important function in auxin action.
植物生长激素生长素在多种植物生长和发育过程中发挥着重要作用。转录因子的鉴定，其中一些具有明确的遗传功能，为生长素调控基因表达的机制提供了新的线索。此外，生长素应答所需基因的分子特征表明，泛素-蛋白酶体途径介导的蛋白质降解在生长素作用中具有重要功能。
