## TL;DR

This paper reports the complete genome sequences of seven Ralstonia solanacearum strains causing Moko disease in Ecuador.

## Contribution

The study provides new complete genome sequences of Ralstonia solanacearum isolates from Ecuador.

## Key findings

- Seven complete genome sequences of Ralstonia solanacearum phylotype IIB-4C/IIB-4E were published.
- The genome megaplasmid contains a class D beta-lactamase gene.

## Abstract

Ralstonia solanacearum has been causing an epidemic of Moko disease in Ecuador since early 2024. Here, we announce the publication of seven complete genome sequences from isolates belonging to the phylotype IIB sequevar IIB-4 and subclade IIB-4C/IIB-4E. Their genome megaplasmid is predicted to contain a class D beta-lactamase gene.
