| Abstract: | We isolated the ipdc gene coding for indole-3-pyruvic acid decarboxylase (IPDC), a key enzyme in the indole-3-pyruvic acid pathway for indole-3-acetic acid biosynthesis, in the plant growth-promoting rhizobacterium Azospirillum lipoferum FS. Gel mobility-shift assay showed the presence of two DNA-binding proteins that might be involved in regulation of the ipdc gene expression. |
