Identification of Genes Involved in Indole-3-Acetic Acid Biosynthesis by PAL5 Strain Using Transposon Mutagenesis.

is a beneficial nitrogen-fixing endophyte found in association with sugarcane plants and other important crops. Beneficial effects of on sugarcane growth and productivity have been attributed to biological nitrogen fixation process and production of phytohormones especially indole-3-acetic acid (IAA); however, information about the biosynthesis and function of IAA in is still scarce. Therefore, the aim of this work was to identify genes and pathways involved in IAA biosynthesis in this bacterium.
