Population diversity of ORFan genes in Escherichia coli.

Genome biology and evolution - 1 Jan 2012

Yu Guoqin, Stoltzfus Arlin

Abstract excerpt

The origin and evolution of "ORFans" (suspected genes without known relatives) remain unclear. Here, we take advantage of a unique opportunity to examine the population diversity of thousands of ORFans, based on a collection of 35 complete genomes of isolates of Escherichia coli and Shigella (which is included phylogenetically within E. coli). As expected from previous studies, ORFans are shorter and AT-richer in...
