Birth and death of orphan genes in Rickettsia.

Molecular biology and evolution - 1 Oct 2003

Amiri Haleh, Davids Wagied, Andersson Siv G E

Abstract excerpt

The origin and evolution of the thousands of species-specific genes with unknown functions, the so-called orphan genes, has been a mystery. Here, we have studied the rates and patterns of orphan sequence evolution, using the Rickettsia as our reference system. Of the Rickettsia conorii orphans examined in this study, 80% were found to be short gene fragments or fusions of short segments from neighboring genes. We...
