Bacterial genera distribution of the PGP potential.

Percentage distribution of plant growth promoting activities and tolerance to abiotic stress according to the genera of the bacterial collection obtained from the pepper root system and the non-cultivated arid soil. Auxin = auxin production; P Sol. = inorganic phosphate solubilization; EPS = exopolysaccharide release; Sid. = siderophores production; NH3 = ammonia production; Prot. = protease activity; PEG = poly-ethylen-glycol.
