In Arabidopsis thaliana, a mature mesophyll cell contains approximately 100 chloroplasts. Although 12 arc mutants (accumulation and replication of chloroplasts) and two chloroplast division genes homologous to eubacterial ftsZ have been isolated from A. thaliana, the molecular mechanism underlying the chloroplast division is still unclear. We characterized AtMinD1, a eubacterial minD homolog, for chloroplast division in A. thaliana. AtMinD1-green fluorescent protein targeted to the chloroplasts and possibly associated with the envelope membranes in vivo. During the seed germination, the AtMinD1 transcripts were accumulated twice, just after release from cold treatment and at the beginning of rapid greening, in similar fashion to AtFtsZs. Furthermore the transcript level in a severest chloroplast division mutant, arc6, was 3–5-fold higher than that in wild-type.
