UK Team Sequences Genome of Potato Rot Bacterium

NEW YORK, July 20 (GenomeWeb News) - A team of researchers led by the Wellcome Trust Sanger Institute has sequenced the genome of Erwinia carotovora (Eca) subsp. atroseptica, a member of the Enterobacteriaceae bacterial family that causes soft rot and blackleg in potatoes.


The team published its analysis of the five million-bp genome for Eca strain SCRI1043 in today's online version of the Proceedings of the National Academy of Sciences.


Analysis of the organism's genome, sequenced to 10.2-fold coverage, revealed 4,491 predicted coding sequences. Around 33 percent of these putative genes are not shared with sequenced enterobacterial human pathogens, such as Salmonella, Yersinia, and Shigella, and may be involved in pathogenicity and metabolism, according to the researchers.
