Abstract

Serratia plymuthica are plant-associated, plant beneficial species belonging to the family Enterobacteriaceae. The members of the genus Serratia are ubiquitous in nature and their life style varies from endophytic to free-living. S. plymuthica AS9 is of special interest for its ability to inhibit fungal pathogens of rapeseed and to promote plant growth. The genome of S. plymuthica AS9 comprises a 5,442,880 bp long circular chromosome that consists of 4,952 protein-coding genes, 87 tRNA genes and 7 rRNA operons. This genome is part of the project entitled "Genomics of four rapeseed plant growth promoting bacteria with antagonistic effect on plant pathogens" awarded through the 2010 DOE-JGI Community Sequencing Program (CSP2010).

Keywords: CSP 2010; Enterobacteriaceae; Gram-negative; chemoorganotrophic; free living; mesophile; motile; non-sporulating; plant-associated.

Phylogenetic tree highlighting the position of S. plymuthica AS9 in relation to other species within the genus Serratia, which is based on 1,479 characters of the 16S rRNA gene sequence aligned in ClustalW2 [7]. The tree was inferred under the maximum likelihood criterion [MEGA5, 8] and rooted with Yersinia pseudotuberculosis (a member of the family Enterobacteriaceae). The branches are scaled in terms of the expected number of substitutions per site. The numbers above branches are support values from 1,000 bootstrap replicates if larger than 60% [9]. Lineages with type strain genome sequences registered in GOLD [10] are shown in blue.
