## TL;DR

This paper presents the draft genome of a microbe isolated from a common seaweed in Singapore, revealing its unique genetic capabilities.

## Contribution

The study provides a new draft genome with insights into the microbe's metabolic and signaling potential.

## Key findings

- The genome includes genes for dimethylsulfoniopropionate assimilation and lignin-related compound degradation.
- It contains biosynthesis pathways for multiple vitamin Bs and quorum sensing-related luxI-luxR homologs.

## Abstract

Sagittula sp. SSi028 was isolated from the globally distributed brown alga Sargassum ilicifolium, which is the most abundant seaweed in Singapore. Its genome contains genes for two dimethylsulfoniopropionate assimilation pathways, degradation of lignin-related aromatic compounds, biosynthesis of multiple vitamin Bs, and luxI-luxR homologs associated with quorum sensing.
