Connecting the Lab and the Field: Genome Analysis of Phyllobacterium and Rhizobium Strains and Field Performance on Two Vegetable Crops

The legume nodules are a rich source not only of rhizobia but also endophytic bacteria exhibiting plant growth-promoting mechanisms with potential as biostimulants. In this work we analyzed the genomes Phyllobacterium endophyticum PEPV15 and Rhizobium laguerreae PEPV16 strains, both isolated from Phaseolus vulgaris nodules. silico analysis showed that these two strains contain genes related to N-acyl-homoserine lactone (AHL) cellulose biosynthesis, involved in quorum sensing biofilm formation, which essential for colonization. Several growth promotion such those phosphate solubilization, indole acetic acid production, siderophore biosynthesis nitrogen fixation were located genomes. When inoculated lettuce carrot field assays, found significantly increased yield shoots roots by more than 20% 10%, respectively. results confirmed genome mining colonization is good strategy predicting bacterial crops inoculants, opening new horizons selection design new, effective bacteria-based
