Role of Bacteria-Derived Flavins in Plant Growth Promotion and Phytochemical Accumulation in Leafy Vegetables.

ABSTRACT: Sinorhizobium meliloti 1021 bacteria secretes a considerable amount of flavins (FLs) and can form a nitrogen-fixing symbiosis with legumes. This strain is also associated with non-legume plants. However, its role in plant growth promotion (PGP) of non-legumes is not well understood. The present study evaluated the growth and development of lettuce (Lactuca sativa) and kale (Brassica oleracea var. acephala) plants inoculated with S. meliloti 1021 (FL⁺) and its mutant 1021ΔribBA, with a limited ability to secrete FLs (FL^-). The results from this study indicated that inoculation with 1021 significantly (p < 0.05) increased the lengths and surface areas of the roots and hypocotyls of the seedlings compared to 1021ΔribBA.
