The Diversity of Culture-Dependent Gram-Negative Rhizobacteria Associated with Manihot esculenta Crantz Plants Subjected to Water-Deficit Stress

There is a lack of studies on the root-associated bacterial microbiome cassava plants. The identification and characterization rhizobacteria can contribute to understanding adaptation agriculturally important crop plants abiotic stress. Rhizobacteria play significant role in plants, as they alleviate drought stress by various mechanisms that enhance plant growth under these stressor conditions. In this study, Gram-negative strains from rhizosphere Manihot esculenta Crantz CIAT MCOL1734 variety subjected water deprivation were isolated, characterized according their morphological properties, then identified VITEK® 2. An increase diversity, abundance, species richness rhizobacterial community was found water-deficit total, 58 isolated process bacteria belonged 12 genera: Achromobacter, Acinetobacter, Aeromonas, Buttiauxella, Cronobacter, Klebsiella, Ochrobactrum, Pluralibacter, Pseudomonas, Rhizobium, Serratia, Sphingomonas. Interestingly, Pseudomonas luteola Ocrhobactrum anthropi exclusively submitted roots constitute great reservoir with remarkable potential for biotechnological application improve tolerance crops
