I have often admired the way interior designers choose just the right large accessory to make what they often call a statement.
This was followed by selective embolisation of the left hepatic artery and of a large accessory left hepatic artery arising from the left gastric artery (Fig. 2).
GDI has a large accessory region (GI15) with at least 40 genes predicted to encode functions related to motility.
Sequence analyzes show the existence of a large accessory genome, probably originated by extensive Horizontal Gene Transfer (HGT).
First, B. terrae BS001 had the largest genome of all (11.5 Mb compared with 9.7 Mb for B. xenovorans LB400), indicating a large accessory gene part.
Clone TB is endowed with a large accessory genome including the genomic islands PAGI-1, PAGI-2, PAGI-5 and PAGI-6 [ 16].
The maintenance of a diverse bacterial community consisting of phylotypes with large accessory gene contents is suggestive of niche differentiation within the phylotypes.
Other than the meningococcal cps region, which encodes the polysaccharide capsule, relatively few members of the large accessory gene pool are exclusive to one species group, and cross-species recombination within this accessory genome is frequent.
Alternatively, there might have been strong selection for the loss of these large accessory proteins early in genome reduction (Lee and Marx 2012), although the cost of having these large proteins for OIEs is not clear.
The results of this study, which involved end-sequencing of ca. 2000 fosmid clones suggest that " H. walsbyi" shares a large accessory gene pool that could easily exceed the size of the sequenced strain's genome.
Despite the presence of large accessory gene pools, the gene order of the genomes was highly conserved within the groups, with strain-specific genes scattered along backbones of conserved core genes.
