Abstract
The translation mechanism of chloroplast mRNAs originated as prokaryotic-type, but has since evolved considerably. Chloroplast translation became, in large part, uncoupled from transcription, and turned into a highly regulated process. Concomitantly, chloroplast ribosomes, general translation factors, and transcripts changed substantially from their prokaryotic counterparts. A multitude of nucleus encoded regulatory proteins evolved that interact in a specific manner with elements in mRNAs to allow translation regulation in response to environmental and developmental cues. In this chapter, we sum up the current knowledge regarding the translation machinery in the chloroplast using examples of mechanisms utilized for chloroplast translation regulation.
