Abstract

ABSTRACTWe report here the whole-genome sequence of Nostoc cycadae strain WK-1, which was isolated from cyanobacterial colonies growing in the coralloid roots of the gymnosperm Cycas revoluta. It can provide valuable resources to study the mutualistic relationships and the syntrophic metabolisms between the cyanobacterial symbiont and the host plant, C. revoluta.

Highlights

We report here the whole-genome sequence of Nostoc cycadae strain WK-1, which was isolated from cyanobacterial colonies growing in the coralloid roots of the gymnosperm Cycas revoluta
A number of scaffolds obviously derived from contaminated bacteria were removed by manual curation using a BLAST search
Gene annotation was performed by MiGAP [9] and by manual curation referring to CyanoBase [10, 11]

Summary

Introduction

We report here the whole-genome sequence of Nostoc cycadae strain WK-1, which was isolated from cyanobacterial colonies growing in the coralloid roots of the gymnosperm Cycas revoluta. A number of scaffolds obviously derived from contaminated bacteria were removed by manual curation using a BLAST search. We obtained 68 cyanobacterium-derived scaffolds with high similarity to the genus Nostoc.
