# Complete genome sequence of the unique Rhizobium johnstonii strain NaPi

## TL;DR

This paper presents the complete genome sequence of a Rhizobium johnstonii strain that forms efficient root nodules on pea plants.

## Contribution

The study provides the first complete genome sequence of the Rhizobium johnstonii strain NaPi.

## Key findings

- Strain NaPi forms large pink nodules on pea mutants lacking the Sym40 gene.
- The complete genome sequence of NaPi has been determined.
- The genetic basis for its nodulation efficiency remains to be identified.

## Abstract

In contrast to Rhizobium johnstonii strain 3841, R. johnstonii strain NaPi is able to form large pink nodules on the roots of pea (Pisum sativum L.) mutants in the gene Sym40. The genetic determinants underlying such efficiency have not been discovered yet. In this study, we report the complete genome sequence of the strain NaPi.
