Abstract


Most pseudomonas isolated from the plant rhizosphere favor the growth of plants through direct and indirect mechanisms. These bacteria produce phytohormones that promote plant growth and produce secondary metabolites that inhibit the growth of pathogenic bacteria and fungi, ensuring crop health. The present review is a compilation on the characterization of Pseudomonas aurantiaca SR1 and its role in the promotion of growth on several crops and its capacity to produce secondary metabolites involved in the control of pathogenic fungi. Pseudomonas aurantiaca SR1, a subspecie of Pseudomonas chlororaphis, produces IAA, HCN, siderophores , phenazines, and quorum, among other abilities. It has shown antifungal activity against several pathogenic strains, among them, Fusarium, Pythium, Rhizoctonia and Sclerotium spp. The SR1 aurantiaca strain has been shown to be a plant growth promoter for various crops, such as alfalfa, wheat, soybean, maize, carob, sugar cane, as well as promoting germination and obtaining vigorous and healthy seedlings. Pseudomonas chlororaphis subsp aurantiana SR1 is currently marketed as PSA liquid from BIAGRO-BAYER Laboratory.
