Project description:From garden soil, we isolated and sequenced Massilia sp. strain ONC3, a new member of the Oxalobacteraceae within the Massilia genus. Sequence analysis showed an assembled genome size of 5,622,601 bp, with a predicted total of 5,104 protein-coding sequences, 3,194 functionally assigned genes, 2 rRNA operons, and 56 tRNAs.
