A number of studies have been reported positive interactions between free-living, nitrogen-fixing rhizosphere bacteria belonging to the genera Azotobacter
and Azospirillum and different plant species [5,8,26].
Also the effect of mycorriza and Azotobacter
inoculation was significant on all measured traits except for Number of days to maturity.
Effect of inoculation with VA mycorrhiza and azotobacter
on grain yield, LAI and protein of wheat on drought stress condition.
strains altered growth characteristics and total phenolic content of garden thyme (Table 1).
Many different genera of plant growth promoting rhizobacteria such as Azospirillum, Azotobacter
, Bacillus, Enterobacter and Pseudomonas have been used as biofertilizer for economically important crops .
Most of bacteria which are used as biological fertilizers included genera of Azotobacter
, Azospirilium, Pseudomonas and Bacillus .
FUNCTIONAL ANALYSIS OF A ModC HOMOLOG IN THE Azotobacter
vinelandii nif-GENE CLUSTER
Inoculation of Azotobacter
and Azospirillum, either alone or in combination, significantly increased the amount of total nitrogen in the rhizosphere soils up to tillering, followed by a gradual decline until maturity of the crop (Fig.
THE ROLE OF NIF-SPECIFIC CLPX IN AZOTOBACTER
Organic supplementation with organic sources such as manure, compost or vermiculite, along with agricultural inoculants such as Rhizobacteria and Azotobacter
could further enhance crop yield and development.
1]) and sub plots were nitroxin (bacteria azospirillum, azotobacter
and pseudomonas) with three levels (zero, 0.
To further determine the role of each of these mutations in the functions of NifM, the homologous amino acids in Azotobacter
vinelandii NifM were identified as Met99 and Arg100 by ClustalW sequence alignment.
