Abstract: | For years, growth-promoting rhizobacteria have been a topic of interest. Indole3-acetic acid or IAA is one of the principal hormones that can be find in these species. In this study, we have gathered all the evidence so far about IAA biosynthesis. Besides, we have followed the same procedure for the substrate of the IAA pathways (tryptophan). For each one of the identified species and pathways, genes and proteins sequences that are involved have been obtained. We have analyzed these gene pool diversity through phylogenetic analysis, and at the same time we have documented their protein profile and co-occurrence level. In order to study their origin and evolution, comparisons using the phylogenetic marker gyrB have been performed. Results show high co-occurrence (both at enzyme/pathway level), that in some cases can be justified attending to the existence of operons. Besides, several differences of interest have been found in the gyrB comparisons |
