摘　　要：不定根由非根器官发育而来,其发育已成为大多数木本植物无性繁殖和工厂化育苗的限制因素,而相关的分子机制还未完全搞清楚。本文介绍生长素与不定根形成关系的基础上,主要针对几种木本植物不定根发生的相关调控基因综述了近年来的研究进展,探讨不定根形成的分子机制,不仅具有重要的理论意义,而且具有潜在的应用价值。Adventitious root is developed from non-root organ of plant.Adventitious root formation has become a limited factor in vegetative propagation and industrialized seedling culture techniques of many woody species.However,the molecular mechanisms underlying adventitious rooting are still not completely clear.Besides introducing the relationship between auxin and adventitious root formation,we reviewed the research processes mainly on the gene regulation related to adventitious rooting of woody species in recent years.To explore the molecular mechanism of adventitious root formation not only has the important significance of theory,but also has potential application value.
