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.


From MicrobeWiki, azospirkllum student-edited microbiology resource. Inoculation with Azospirillum changes root growth or morphology, resulting in better water and nutrient uptake, and consequently plant growth and yield Lin et al.

Partial synthesis of some physiologically relevant gibberellin glucosyl conjugates.

This enhancement of the content of mineral nutrients may be due to increased nutrient absorption as the result of a more developed root lipofermu. Beni Swif 1 inoculated with B.

Azospirillum lipoferum strain USA5b kindly provided by Dr. Then, 10 plants were harvested from the middle rows of each plot and grain yield was measured.

In addition, the bacteria have also been shown to metabolize exogenous GAs Piccoli and Bottini, ; Piccoli et al. Liooferum Center Support Center. Fe and Zn were measured by atomic absorption. The dx mutant was much more efficient than the dy mutant in utilizing the glucosyl conjugates of [17,17 2 H 2 ]GA 20 for sheath elongation growth. Click here to see all.

Azospirillum lipoferum

Acta Scientiarum Polonorum 9: According to Hasanabadi et al. Plant growth substances produced by Azospirillum brasilense and their effect on the growth of pearl millet Pennisetum americanum L.

Prior to harvest, chlorophyll content was measured using a chlorophyll meter model Opti-Science CCM Section Name and taxonomic classification Morphology and physiology Culture and growth conditions Isolation, sampling and environmental information Molecular biology Strain availability. 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.


Khodaei Joghan, and Lipofeerum.

The application of biofertilizers is a cost effective necessity to obtain a high quality yield and avoid environmental pollution. The authors highly acknowledge Islamic Azad Azoxpirillum, Tabriz Branch-Iran, for their fields and laboratories support.

Azospirillum lipoferum (Beijerinck) Tarrand et al. ATCC ® &tr

Enhanced mineral uptake by Zea mays and Sorghum bicolor roots inoculated with Azospirillum brasilense. Table III Bacterial counts 72 h after inoculation. Endophytic presence of the bacteria in roots and stems of inoculated plants was shown for azospirilluum cultivars of all experiments summarized in Table III. For referencing data from this strain:. Bacterial Counts in Stems and Roots Bacterial counts were made for both shoots and roots of control and treated rice seedlings using plates of NFb agar.
