Corn seed inoculation with Azospirillum brasilense in different nitrogen fertilization management

(Methyl)ammonium transport in the nitrogen-fixing bacterium Azospirillum brasilense.

An ammonium transporter of Azospirillum brasilense was characterized. In contrast to most previously reported putative prokaryotic NH4+ transporter genes, A. brasilense amtB is not part of an operon with glnB or glnZ which, in A. brasilense, encode nitrogen regulatory proteins PII and PZ, respectively. Sequence analysis predicts the presence of 12 transmembrane domains in the deduced AmtB prote...

Effect of seed inoculation with Azotobacter and Azospirillum and different nitrogen levels on yield and yield components of canola (Brassica napus L.) , Mahboobeh Naderifar1*, Jahanfar Daneshian2

In order to investigate the effect of different levels of nitrogen and bio-fertilizers on yield of canola plants in Qazvin, Iran, a split-plot design was conducted on the base of randomized complete block design with four replications. Treatments included 3 levels of nitrogen (0, 75 and 150 kg ha-1) and bio-fertilizers on four levels (no inoculation, Azotobacter, Azospirillum and a combination ...

Responses of Soybean and Cowpea Root Membranes to Inoculation with Azospirillum brasilense

Inoculation with Azospirillum brasilense Cd of two leguminous species, soybean (Glycine max) and cowpea (Vigna unguiculata), demonstrated that: (1) A. brasilense significantly increased proton efflux from their roots; (2) inoculation reduced plant membrane potential (in soybean), (3) inoculation changed the phospholipid quantity in plant membranes of calli (in cowpea), and (4) a low molecular w...

Plant-Soil-Microorganism Interactions on Nitrogen Cycle: Azospirillum Inoculation

Reparation of aged lettuce (Lactuca sativa) seeds by osmotic priming and Azospirillum brasilense inoculation

Although Azospirillum spp. are considered to be important plant growth promoting bacteria, their possible effects on germination and vigor of aged lettuce seeds has not been previously evaluated. In fact, there is a paucity of published data about inoculation effects on seed germination. The aim of this work was to evaluate seed quality of oneyear aged lettuce (Lactuca sativa L. cv. Crimor INTA...
