| Outline of Final Research Achievements |
It is believed that, with some exceptions, plastids and mitochondria in eukaryotic organisms have two envelopes without a peptidoglycan wall (murein). However, we previously demonstrated that Mur(ein) genes in the moss Physcomitrella patens genome are associated with chloroplast division. In this study, we found the peptidoglycan wall surrounding chloroplasts in the P. patens cells using metabolic labeling with a D-Ala-D-Ala dipeptide probe and click chemistry. Moreover, we isolated and analyzed new genes and proteins that are related to plastid peptidoglycan.
