Title: Metagenomic Assessment Of The Rhizobacteria Community Diversity Of Different Cassava Cultivars


The rhizosphere community of plants are in close interaction with a diversity of microorganisms which plays critical roles in determining the growth and development of the plant they inhabit. This region supports the availability of a vast array of  microorganism with genetic signatures capable of promoting plant growth through diverse mechanisms. Plant well being and growth is defined by the type and class of microorganisms colonising its roots and other plant parts and this study presents the dataset of the rhizobacteria community profile of two different cassava cultivars from Iyamho community, Edo State Nigeria. To the best of our knowledge, this is the first account showcasing the profile of bacteria in different cassava varieties. Samples were collected from the rhizosphere of the each cassava cultivar within Edo state university Uzairue Latitude 7.13419° or 7° 8' 3" north and Longitude 6.30252° or 6° 18' 9” east. The samples were identified as Sweet Cassava, CV1 (EUH/00098) and Bitter Cassava, CV2 (EUH/00099).  The high throughput illumina Miseq sequencing of the 16S rRNA gene amplicon revealed the bacterial  reads for CVI and CV2 as  24696.0 and 22968.0 reads, respectively. The USEARCH analysis at phylum level showed the presence of Proteobacteria 29.00%, Actinobacteria 20.55%, Planctomycetota 14.56% , Firmicutes 7.99%, Acidobacteriota 6.14% for CV1 while Actinobacteriota 27.56%, Planctomycetota 17.48%, Proteobacteria 16.54%, Firmicutes  9.11%, Acidobacteriota 7.13% for CV 2. The results revealed similar bacterial community structure in both cassava cultivars but a significant difference in their various percentage of occurrence which could account for the difference in the cassava growth, development and content. These bacterial population diversity accounts for the production and yield recorded in both cultivars.
