Alleviation of chromium toxicity in mung bean (Vigna radiata L.) using salicylic acid and Azospirillum brasilense [PDF]

BMC Plant Biology, 2023
Background Chromium (Cr) contamination in soil poses a serious hazard because it hinders plant growth, which eventually reduces crop yield and raises the possibility of a food shortage.

Gas Exchange, Root Morphology and Nutrients in Maize Plants Inoculated with Azospirillum brasilense Cultivated Under Two Water Conditions [PDF]

Brazilian Archives of Biology and Technology, 2021
HIGHLIGHTS Azospirillum brasilense stimulates root growth in maize under water deficit. Maize inoculated with A. brasilense shows greater photosynthesis under drought conditions. Under water deficit, maize plants inoculated with A. brasilense showed

Regulation of nitrogen fixation in Azospirillum brasilense [PDF]

FEMS Microbiology Letters, 2006
The regulation of nitrogen fixation in Azospirillum brasilense is very complicated, and it responds to exogenous fixed nitrogen or a change of oxygen concentration. This regulation occurs at both transcriptional and posttranslational levels. Unlike regulation seen in Klebsiella pneumoniae, transcription of nifA does not require NTRB/NTRC in A ...

Plasmid transformation ofAzospirillum brasilense [PDF]

FEMS Microbiology Letters, 1986
Plasmid transformation of the nitrogen-fixing bacterium Azospirillum brasilense is described. A modification of the method of Hanahan [1] was used to transform this bacterium with the 20-kb plasmid pRK290. The efficiency of transformation ranged from 200–1000 transformants per μg of plasmid DNA according to DNA concentration.

EFFICIENCY OF USING BIOFERTILIZATION IN REDUCING NITROGEN FERTILIZER APPLICATION AND THEIR EFFECT ON GERMINATION, GROWTH AND YIELD OF MAIZE (Zea mays L.) [PDF]

Journal of Plant Production, 2013
A laboratory study was designed to investigate the influence of seed inoculation treatments with cerialein (Azospirillum brasilense),  phosphorein (Bacillus megaterium) and mixture from both on germination and seed vigor of maize (SH.

Fructose catabolism in Azospirillum brasilense and Azospirillum lipoferum [PDF]

Journal of Bacteriology, 1984
The pathways for catabolism of fructose were investigated in the type strains of Azospirillum lipoferum and Azospirillum brasilense grown aerobically with (NH4)2SO4 as the nitrogen source. When grown on fructose, the former species possessed a complete Entner-Doudoroff pathway, whereas the latter species lacked activity for glucose-6-phosphate ...

Co-inoculation of Azospirillum with mycorrhizal fungi in the cultivation of wheat in soils contaminated with copper

Semina: Ciências Agrárias, 2023
Copper is a micronutrient essential for plant growth since it is part of the constitution of enzymes and proteins. However, it can become toxic to plants when in high concentrations in the soil.

Aerotactic response of Azospirillum brasilense [PDF]

Journal of Bacteriology, 1982
Five strains of Azospirillum brasilense and two of Azospirillum spp., from Israel, responded to self-created and preformed oxygen gradients by forming aerotactic bands in capillary tubes and actively moving toward a specific zone with low dissolved oxygen.

The random walk ofAzospirillum brasilense [PDF]

Journal of Biological Dynamics, 2010
The bacterium Azospirillum brasilense has been frequently studied in laboratory experiments. It performs movements in space where long forward and backward runs on a straight line occur simultaneously with slow changes of direction of the line. A model is presented in which a correlated random walk on a line is joined to diffusion on a sphere of ...

Intermediary carbon metabolism of Azospirillum brasilense [PDF]

Journal of Bacteriology, 1984
Azospirillum brasilense Sp 7 grew rapidly in AZO medium containing reduced nitrogen and succinate as an energy source, with a doubling time of 43 min. No growth was measured with glucose as the sole carbon source. In contrast, Azospirillum lipoferum Sp 59b could grow in media containing either succinate or glucose with a doubling time of 69 min and 223
