The ability of Azospirillum to colonize the roots of plants depends on motility and chemotaxis. Azospirillum cells are motile and capable of chemotaxis toward organic acids, sugars, and some aminoacids. Azospirillum is also able to navigate gradients of oxygen, alternative electron acceptors, and redox active compounds.

AZOSPIRILLUM INOCULATION ON SUGARCANE
Madras Agricultural Journal, 1996Field experiments were conducted at the Sugarcane Research Station, Cuddalore with the objective of finding out the use of Azospirillum sp. as a supplemental source of N in sugarcane crop cv Co. 6304. Application of 7 kg of Azospirillum sp. along with 225 kg of N ha recorded same cane yield to that of 300 kg N ha", resulting in a saving of 75 kg N ha ...

Publisher Summary This chapter discusses the studies focusing on cultures of Spirillum lipoferum (Azospirillum). The recent isolation of the N2-fixing bacterium Azospirillum has initiated numerous investigations of this organism. Azospirillum can fix N2 either as a free-living organism or in association with plant roots.

Pleomorphism in azospirilla appears to be induced by medium composition rather than pH. Complex organic media stimulate it and it is more pronounced in Azospirillum lipoferum than in A. brasilense. Besides ‘capsules’, protoplasmic globular structures (free protoplasts) sometimes may be produced. Under certain conditions the smaller cells appear to have

Phylogenetic Studies of the Genus Azospirillum
1995The 16S rDNA of seventeen Azospirillum strains, fourteen of which assigned to one of known A. amazonense, A. brasilense, A. halopraeferens, A. irakense and A. lipoferum species, and other three of uncertain taxonomic collocation, was sequenced and analysed after polymerase chain reaction amplification, in order to investigate the phylogenetic ...

Azospirillum-Plant Interaction
2014Bacteria of the genus Azospirillum (alpha-proteobacteria) have been known for many years as plant growth-promoting rhizobacteria (PGPR) (Döbereiner and Day 1976). These free-living nitrogen-fi xing highly motile bacteria can be isolated from the rhizosphere of many grasses and cereals under tropical and temperate climates (Döbereiner et al.

[Plasmids of Azospirillum brasilense].
Molekuliarnaia genetika, mikrobiologiia i virusologiia, 1987The cells from natural isolates of A. Brasilense were found to harbour 1 to 4 plasmids with the molecular masses within the 27-300 Md range. 100 Md plasmids are specific for this bacterial species. Strains isolated from the roots of cereals (wheat, maize, barley) have more heterogeneous plasmid composition as compared to the strains isolated from soil.

Azospirillum and Wheat Production
2017This review aims to elucidate the actual effect of Azospirillum spp. on wheat production under field condition and represent methods by which it can enhance the beneficial effect of Azospirillum on wheat. The bacterial genus Azospirillum is well known as a plant growth-promoting bacteria (PGPR).
