Genes encoding pentatricopeptide repeat (PPR) proteins are not conserved in location in plant genomes and may be subject to diversifying selection.

BMC genomics - 23 May 2007

Geddy Rachel, Brown Gregory G

Abstract excerpt

BACKGROUND: The pentatricopeptide repeat (PPR) is a degenerate 35 amino acid motif that occurs in multiple tandem copies in members of a recently recognized eukaryotic gene family. Most analyzed eukaryotic genomes contain only a small number of PPR genes, but in plants the family is greatly expanded. The factors that underlie the expansion of this gene family in plants are not as yet understood. RESULTS: We show...
