RNA splicing and RNA editing in chloroplasts

Chapter
Part of the Topics in Current Genetics book series (TCG, volume 19)

Abstract

During the evolution of chloroplasts from their bacterial ancestor traits emerged that are absentor rare in bacteria. Prominent among these acquired traits are RNA splicing and RNA editing. Thenumbers and distribution of introns and editing sites in different taxa suggest that editing and splicinghave taken different evolutionary pathways in different chloroplast lineages. Both processes aredependent on nuclear-encoded factors and, intriguingly, PPR (pentatricopeptide repeat) proteins haverecently been recognized as a common player. This review summarizes recent progress in understandingthe mechanisms, regulation, and trans-acting factors for thesetwo types of RNA processing.
