专利号:US-6051383-A 优先权日:1995-06-26 标题:Sequences for production of 2,4-diacetylphloroglucinol and methods 发明人:THOMASHOW LINDA S; BANGERA MAHALAXMI; WELLER DAVID M; COOK R JAMES 权利人:US AGRICULTURE; UNIV WASHINGTON 摘要:DNA sequences which function specifically in the synthesis of 2,4-diacetylphloroglucinol (Phl) are described. The sequences include phl genes which encode phl gene proteins and coding and regulatory sequences for production of Phl as well as sequences containing phl genes, which sequences have the capability of conferring or enhancing Phl biosynthetic capability in bacterial strains. The transformed strains are useful as biocontrol agents against fungal pathogens.
