Restriction endonucleases in Azospirillum
Gene, 1985Azospirillum brasilense, A. amazonense, and A. lipoferum strains were screened for restriction endonucleases using phage lambda DNA. The extract of A. brasilense 29711 cleaved lambda DNA into specific fragments. It was concluded that this strain possesses a class II restriction endonuclease which was named AbrI.

Pseudomonas strains are fast growing, genetically diverse and metabolically versatile bacteria. Many pseudomonad species are preferential inhabitants of the rhizosphere of plants, reaching up to 108 CFU/g of roots for crop species like soybean or maize in the field.

Mutation in Azospirillum Brasilense
1985In order to study mutation frequencies in A. brasilense two selective systems, i. e. resistance to 5-Fluorotryptophan and to Rifampicin, were set up. The rate of mutation in this organism after treatments with several mutagens has been investigated.

Homology between plasmids of Azospirillum brasilense and Azospirillum lipoferum
1989Azospirillum strains examined so far contain large plasmids with which no phenotypic property has been associated. Homology was previously detected between total DNA from several Azospirillum strains and Rhizobium meliloti nodulation (nod and hsn) genes, which in Rhizobium are plasmid-borne. From A.

Molecular relationship of an atypical Azospirillum strain 4T to other Azospirillum species
Research in Microbiology, 1994DNA/DNA hybridization, plasmid content and partial 16S rDNA sequence were determined to confirm the relationship between two Azospirillum strains, 4B and 4T, isolated from the same rice rhizosphere. The partial 16S rDNA sequence was determined for 9 strains belonging to 5 Azospirillum species which included Azospirillum lipoferum strains 4B and 4T, and

Cell-Surface Lectins of Azospirillum spp.
Current Microbiology, 1998Cell-surface lectins were screened in seven strains of Azospirillum brasilense and A. lipoferum. The presence of lectins was determined by particle agglutination assays employing latex beads coated with neoglycoproteins and by Western blot with neoglycoproteins labeled with horseradish peroxidase as a probe.

Inoculation of Zerna inermis with azospirilum bacteria results in associated nitrogen fixation activity increase and initiation of plant development. Specimens of Azospirilum brasilense only were settled down in root zone. A. lipoferum influence on parameters increase indirectly ??? due to physiologically active substances (PAS) of inoculums.

Polyhydroxybutyrate in Azospirillum brasilense
2015Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate produced by several bacteria as carbon storage and reductive equivalents sink. The production of PHB has been reported for several plant-associated bacteria, and especially in Azospirillum brasilense, the production of PHB has been associated as a factor for stress endurance.
