We isolated a cold sensitive virescent1 (csv1) mutant from a rice (Oryza sativa L.) population mutagenized by carbon ion irradiation. The mutant exhibited chlorotic leaves during the early growth stages, and produced normal green leaves as it grew...
Symmetric division of leaf mesophyll chloroplasts requires MinD and MinE, which work together to suppress division other than at the mid-chloroplast. arc11 is a MinD loss-of-function mutant of Arabidopsis thaliana. In arc11 plants, asymmetric chlo...

Plastids in the leaf epidermal cells of plants are regarded as immature chloroplasts that, like mesophyll chloroplasts, undergo binary fission. While mesophyll chloroplasts have generally been used to study plastid division, recent studies have su...
葉緑体分裂には、進化的に保存されたバクテリア様分裂因子群と真核生物特有のダイナミン様タンパク質が関わる。バクテリア様因子のうちMinDとMinEの二種はバクテリアでは細胞分裂の位置決定に関わる。最近、シロイヌナズナMinE相同因子(AtMinE1)が第三の葉緑体分裂因子として機能すること、またシロイヌナズナ葉緑体分裂異常変異体arc11 (accumulation and replication of chloroplasts 11)がMinD相同...
