By completing the sequencing of the maxicircle conserved region in the kinetoplast DNA ofPhytomonas serpens, we showed that the genes for subunits I and II (COIandCOII) of cytochromecoxidase in this organism were missing. We had previously shown that the genes for cytochromecoxidase subunit III and apocytochromebwere also missing. These deletions did not affect the structure or expression of the remaining genes. Partial editing of the mRNA for NADH dehydrogenase subunit 8, previously found in strain 1G from insects, was complete in two other strains isolated from plants. The appearance of a novel maxicircle gene for MURF2 block I gRNA, which substitutes for the gene missing due to theCOIIgene deletion, may illustrate a general mechanism for the origin of gRNAs.
