Mitochondrial genome sequence of the potato powdery scab pathogen Spongospora subterranea.
Spongospora subterranea is a soil-borne obligate parasite responsible for potato powdery scab disease. S. subterranea is a member of the order Plasmodiophorida, a protist taxa that is related to Cercozoa and Foraminifera but the fine details of these relationships remain unresolved. Currently there is only one available complete mtDNA sequence of a cercozoan, Bigelowiella natans. In this work, the mitochondrial sequence of a S. subterranea isolate infecting an Andean variety of S. tuberosum ssp. andigena (Diacol-Capiro) is presented. The mtDNA codes for 16 proteins of the respiratory chain, 11 ribosomal proteins, 3 ribosomal RNAs, 24 tRNAs, a RNA processing RNaseP, a RNA-directed polymerase, and two proteins of unknown function. This is the first report of a mtDNA genome sequence from a plasmodiophorid and will be useful in clarifying the phylogenetic relationship of this group to other members in the supergroup Rhizaria once more mtDNA sequences are available.
