摘要我们研究了真菌除草剂球孢炭疽菌(Colletotrichum Gloeosporioides f.sp.eschynomene)生物合成吲哚-3-乙酸的过程。生长素的产生依赖于色氨酸。在培养滤液中检测到来自吲哚-3-乙酰胺和吲哚-3-丙酮酸途径的化合物。喂养实验和体外实验证实了这两种途径的存在。吲哚-3-乙酰胺是该真菌在培养过程中产生吲哚-3-乙酸的主要途径。
ABSTRACT We characterized the biosynthesis of indole-3-acetic acid by the mycoherbicide Colletotrichum gloeosporioides f. sp.aeschynomene. Auxin production was tryptophan dependent. Compounds from the indole-3-acetamide and indole-3-pyruvic acid pathways were detected in culture filtrates. Feeding experiments and in vitro assay confirmed the presence of both pathways. Indole-3-acetamide was the major pathway utilized by the fungus to produce indole-3-acetic acid in culture.
