Insights into endophytic bacterial diversity of rice grown across the different agro-ecological regions of West Bengal, India

AbstractEndophytes have recently garnered importance worldwide and multiple studies are being conducted to understand their important role and mechanism of interaction inside plants. But before we indulge in their functions it is necessary to dig into the microbiome. This will help to get a complete picture of the microbes intrinsic to their host and understand changes in community composition with respect to their habitats. To fulfil this requirement in our study we have attempted to dissect the endophytic diversity in roots of rice plant grown across the various agro-ecological zones of West Bengal by undergoing amplicon analysis of their 16S rRNA gene. Based on the measured environmental parameters agro-ecological zones can be divided into two groups: nutrient dense groups, representing zones like Gangetic, Northern hill and Terai-Teesta zone characterised by soil with higher levels of nitrogen (N) and total organic carbon and nutrient low groups representing Coastal saline, Red-laterite and Vindhyan zone mainly characterised by high electroconductivity and pH.Gammaproteobacteria,Alphaproteobacteria,Bacilli andBacteroidetes were mostly abundant in nutrient dense sites whereasClostridia andPlanctomycetes were concentrated in nutrient low sites. Few genera (Aeromonas, Sulfurospirillum, Uliginosibacterium andAcidaminococcus) are present in samples cultivated in all the zones representing the core microbiome of rice in West Bengal, while some other genera likeLactococcus, Dick...
