Profiling of bacterial community associated with sugarcane rhizosphere

Sugarcane (Saccharum officinarum L.) is an important cash crop in India, and its cultivation contributes significantly to the country's economy by producing sugar, bioethanol, and other valuable by-products. The rhizosphere microbiome plays a vital role in nutrient cycling, plant health, and soil functioning. Hence, the soil microbiome associated with sugarcane cultivation plays a crucial role in nutrient cycling, plant health, and overall ecosystem functioning. However, information on the composition and diversity of bacterial communities in sugarcane rhizosphere soils of Uttar Pradesh remains limited. In different places, the outcomes of different cropping systems on the microbiome differ, affecting crop health and productivity. In the present study, bacterial diversity was characterized using 16S rRNA amplicon sequencing across different locations. The results revealed distinct variations in microbial community composition among sites, as supported by beta diversity analysis. Dominant bacterial phyla included Pseudomonadota, Bacillota, Bacteroidota, Actinomycetota, and Acidobacteriota, indicating their potential roles in rhizosphere functioning. These findings provide insights into the structure of sugarcane-associated microbial communities and highlight their importance in sustainable crop production.
