摘　　要：吲哚乙酸(Indole-3-acetic acid,IAA)是自然界中最广泛存在的生长素之一,在植物的生长发育过程中具有极为重要的调节作用。本研究从IAA的生物合成和IAA结合物水解2个方面来阐述植物中控制IAA水平的多条途径,介绍了依赖色氨酸、不依赖色氨酸以及二者共存的IAA生物合成途径和IAA结合物的水解等方面的研究进展,指出进一步研究的关键点是控制多条途径转换的枢纽。As one of the most widespread auxin, Indole-3-acetic acid （IAA） had a very important role in regulating plant growth and development. Multiple approaches to control the levels of IAA in plants were elucidated in this article from two aspects： the IAA biosynthetic and IAA conjugate hydrolysis. Research advances about IAA biosynthesis pathway in which tryptophan-dependent, tryptophan-independent and coexistence of both were included and IAA conjugate hydrolysis were introduced. Finally, the opinion was pointed out that the key point of further research was to control the hub linking multi-way converse.
