## TL;DR

This paper presents the draft genome of a Methylobacterium aquaticum strain found in plant root nodules, suggesting it may help tropical plants through nitrogen fixation.

## Contribution

The study provides a new draft genome sequence and identifies potential symbiotic functions in a Methylobacterium strain.

## Key findings

- The draft genome of Methylobacterium aquaticum LEGMi-203a was successfully sequenced.
- Genomic analysis confirms its classification and reveals genes related to nitrogen fixation and nodulation.

## Abstract

We report the draft genome of Methylobacterium aquaticum LEGMi-203a, a root nodule isolated from Pithecellobium hymenaeifolium. Genomic analysis supports its classification as M. aquaticum, and annotated nitrogen fixation and nodulation genes underscore its possible functional capabilities as a symbiont in tropical plants.
