Inoculated seeds were planted directly in the soil. Search FTB Enter search term Effect of horizontal DNA transfer in Azospirillum and Azotobacter strains on biological and biochemical azospidillum of non-legume plants. Information on morphological and physiological properties Morphology and physiology.

In this work, Azospirillum brasilense strain Cd and Azospirillum lipoferum strain USA 5b promoted sheath elongation growth of two single gene GA-deficient dwarf rice Oryza sativa mutants, dy and dxwhen the inoculated seedlings were supplied with [17, 2 H 2 ]GA 20 -glucosyl ester or [17, 2 H 2 ]GA 20 azospiriolum ether. Azospirillum lipoferumis a free living, gram positive, plant-growth-promoting a-proteobacteria, capable of affecting the growth and yield azospirillhm numerous plant species, many of agronomic and ecological significance.

Approved lists of bacterial names. The interaction of NX Azospirillum showed a significant effect only on the grain yield and the number of seeds in ear.

Open in a separate window. According to Ribaudo et al. The finding that only [17, 2 H 2 ]GA 1 was a metabolic product of [17, 2 H 2 ]GA azospiirillum the deconjugated aglycone strongly implies that GA 1 and GA 3 have different precursors in the route of synthesis in Azospirillum spp.
