Abstract

To gain a broader understanding of the importance of a surface-associated lifestyle and morphogenic capability, we have assembled and annotated the genome sequences of Pseudoalteromonas strains P1-7a, P1-9, P1-13-1a, P1-16-1b, P1-25, and P1-26, isolated from Hydractinia echinata. These genomes will allow detailed studies on bacterial factors mediating interkingdom communication.

Highlights

Pseudoalteromonas strains P1-7a, P1-9, P1-13-1a, P1-16-1b, P1-25, and P1-26 were isolated from the tissue of a feeding polyp of the marine hydroid Hydractinia echinata [1] purchased from the Marine Biological Laboratory in Woods Hole, MA, USA
The draft genome sequence of strain P1-13-1a was sequenced to 51ϫ coverage, and comprises 174 contigs totaling 4,442,776 bases in length and having a GϩC content of 40.7%
The draft genome sequence of strain P1-25 was sequenced to 51ϫ coverage, and comprises 163 contigs totaling 4,399,610 bases in length and having a GϩC content of 40.7%

Summary

Introduction

Pseudoalteromonas strains P1-7a, P1-9, P1-13-1a, P1-16-1b, P1-25, and P1-26 were isolated from the tissue of a feeding polyp of the marine hydroid Hydractinia echinata [1] purchased from the Marine Biological Laboratory in Woods Hole, MA, USA. Six Pseudoalteromonas strains were isolated from H. echinata and screened for their effects on its larval settlement and metamorphosis using a colony-based assay [1].
