Abstract

Azospirillum brasilense is used worldwide as a plant growth-promoting inoculant for agricultural crops. To understand how the genomes of Indian strains of A. brasilense compare with their South American counterparts, we determined the whole-genome sequences of four strains of A. brasilense isolated from the rhizosphere of grasses from India.

Highlights

  • Azospirillum brasilense is used worldwide as a plant growth-promoting inoculant for agricultural crops

  • A search for a CRISPR-Cas system was carried out using CRISPRCasFinder [12]

  • CRISPR arrays were observed in MTCC4035 (n ϭ 4) and MTCC4038 (n ϭ 3), showing the presence of the complete class I type of CRISPR-Cas system

Summary

Introduction

Azospirillum brasilense is used worldwide as a plant growth-promoting inoculant for agricultural crops. The resulting genomes of the four isolates showed variation in size from 7.13 to 8.12 Mb. All assembled circular contigs possessed replication- and transfer-related genes, required for their independent existence as replicons. Their numbers varied from 6 to 9 in these isolates.
