Complete mitochondrial genome of Pseudoperonospora cubensis.

Pseudoperonospora cubensis is a species of water mould known for causing downy mildew on cucurbits. 454 GS FLX Titanium sequencing data was used to obtain its complete mitochondrial genome (38 553 bp). The mitogenome contains 60 genes, including two ribosomal RNA, 25 transfer RNA, 15 ribosomal proteins, five open reading frames (ORFs). The rps3 and rpl16 overlapped each other by 14 bp. The gene order and composition of P. cubensis was similar to that of most other oomycetes, and its GC content was 22.4%. It is the first report of the complete mitochondrial genome in the genus Pseudoperonospora. Phylogeny analysis indicates that P. cubensis has a close genetic relationship with genus Phytophthora.
