Thanks Jeff

Actually these are Amplicon sequencing variant which are differ at single
nucleotide but may belongs to same genus, or further may be same species,
but may be different bacterial strain, so I will think about it what should
I do, may be I can plot with OTU ID and genus together...or can just
aggregate at genus level...could you please suggest how I can aggregate
same genus name ID while importing data into R.

Thanks
Yogesh
