The research studied the 3[prime] end maturation of green algae chloroplast atpB mRNA. Most data on transcription termination and 3[prime] end maturation in chloroplasts have been based on in vitro experiments. Newly developed chloroplast transformation techniques have allowed the use of a green algae, Chlamydomonas reinhardtii, to examine chloroplast mRNA 3[prime] end stability determinants and mRNA processing both in vitro and in vivo. The results of this research showed that Chlamydomonas chloroplast protein extracts contain an endonuclease activity that cleaves a synthetic precursor of atpB mRNA 10 nucleotides downstream on the mature 3[prime] end in vitro. Rapid cleavage by this endonuclease is followed by exonucleolytic removal of 10 nucleotides to yield the mature 3[prime] end.
