Outline of Final Research Achievements |
We found that MurE homologs among the genes which participated in bacterial peptidoglycan synthesis were conserved in all land plants and were functioned in the chloroplast division or development. In complementation analysis using MurE genes in moss Physcomitrella patens and seed plants, we presumed that MurE functioned in the chloroplast development emerged when land plant evolved at the latest, and also one functioned in the chloroplast division was conserved in pteridophyte, although MurE gene conserved in land plants were considered to functionally differentiated from chloroplast division to chloroplast development between pteridophyte and spermatophyte during the evolution of green plants. We could narrow down the mutations of three amino acids which were probably essential in MurE functioned in each chloroplast division and development.
