Abstract
Phage SL20, a novel lytic Pseudoalteromonas phage, was isolated from the coastal waters of the Yellow Sea, China. The microbiological characterization demonstrated that phage SL20 was relatively stable from 35 to 55 °C and the optimal pH was approximately 6.0. A latent period of approximately 24 min was indicated by a one-step growth curve. The burst size was approximately 12 ± 3 PFU/cell. The genome had a length of 120,295 bp with a G + C content of 35.84%, and predicted 95 ORFs. The phylogenetic tree based on DNA helicase showed that Pseudoalteromonas phage SL20 was related to the Pseudoalteromonas phage H101 and was a member of the family Shandongvirus. The isolation and genomic analysis of SL20 has improved our understanding of host-phage interactions and the ecology of the marine bacteria Pseudoalteromonas.
期刊介绍：
The journal publishes papers on all functional and evolutionary aspects of genes, chromatin, chromosomes and (meta)genomes of marine (and freshwater) organisms. It deals with new genome-enabled insights into the broader framework of environmental science. Topics within the scope of this journal include:
• Population genomics and ecology
• Evolutionary and developmental genomics
• Comparative genomics
• Metagenomics
• Environmental genomics
• Systems biology
More specific topics include: geographic and phylogenomic characterization of aquatic organisms, metabolic capacities and pathways of organisms and communities, biogeochemical cycles, genomics and integrative approaches applied to microbial ecology including (meta)transcriptomics and (meta)proteomics, tracking of infectious diseases, environmental stress, global climate change and ecosystem modelling.
