Question

Is Azospirillum in nitrogen fixation?

Answer 1

Azospirillum:

1. Azospirillum can enhance plant development via abiotic stress tolerance mechanisms such as induced systemic tolerance, which is mediated by antioxidants, osmotic adjustment, phytohormone synthesis, and defense strategies such as pathogenesis-related gene expression.
2. Azospirilla is a gram-negative, free-living nitrogen-fixing rhizosphere bacterium.
3. The Azospirillum spp. are plant growth promoting, nitrogen-fixing bacteria which can associate with some cereals such as wheat, maize, and rice and also biofuel crops such as Pennisetum and sugar cane.
