Abstract—

The production of the most studied, active and widespread groups of brassinosteroids by salt-tolerant bacteria Priestia megaterium Ср-1, Rhodococcus jostii CA-6 and Pseudomonas koreensis FP2/1 isolated from saline soil samples was studied. It was shown that the studied bacterial strains are capable of producing steroidal phytohormones of the brassinolide, 24-epibrassinolide and 28-homobrassinolide groups, as well as brassinosteroid B-ketones, B-lactones and 6-deoxo derivatives. This circumstance may be the cause of the growth-stimulating activity of these bacteria and their effect on plant adaptation to stress factors.
