|Outline of Final Research Achievements
The acquisition of chloroplasts was an important event in the evolution of plant cells. Although the plastids of green plants are thought to have lost the ability to produce peptidoglycan (PG) during evolution, we found that the moss Physcomitrella (Physcomitrium patens) use PG for chloroplast division. In this study, structural characterization of moss PG was analyzed. We identified new homologs of bacterial PG genes such as MurJ and MltB to show their relation to moss chloroplast division. Moreover, we visualized chloroplast PG in the charophyte alga Klebsormidium nitens, revealed the presence of peptidoglycan in the intermembrane space of the moss chloroplast envelope, showed diverse origins of enzymes involved in the chloroplast PG synthesis, and analyzed MurE from the gymnosperm Larix gmelinii.
