“…hordei RACE1 isolate is reduced to 107.1 kb, which is comparable to other mt genomes of B. graminis [ 31 ]. Recently, a 26.0 kb mt genome for the PM Podosphaera xanthii has been described [ 58 ], which is considerably smaller than the PM mt genomes presented herein. However, a phylogenetic analysis failed to group the Podosphaera xanthii mt genome with members of the Leotiomycetes [ 58 ], suggesting that this mt genome is not from a PM species.…”

“…Recently, a 26.0 kb mt genome for the PM Podosphaera xanthii has been described [ 58 ], which is considerably smaller than the PM mt genomes presented herein. However, a phylogenetic analysis failed to group the Podosphaera xanthii mt genome with members of the Leotiomycetes [ 58 ], suggesting that this mt genome is not from a PM species. The largest fungal mt genomes reported to date are those of the so-called ‘true morels’ fungi Morchella importuna, M. conica, and M. crassipes, sized at 272238 bp [ 59 ], 280763 bp [ 60 ], and 531195 bp [ 6 ], respectively.…”

Powdery mildews comprise a large group of economically important phytopathogenic fungi. However, limited information exists on their mitochondrial genomes. Here, we assembled and compared the mitochondrial genomes of the powdery mildew pathogens Blumeria graminis f. sp. tritici, Erysiphe pisi, and Golovinomyces cichoracearum. Included in the comparative analysis was also the mitochondrial genome of Erysiphe necator that was previously analysed. The mitochondrial genomes of the four Erysiphales exhibit a similar gene content and organization but a large variation in size, with sizes ranging from 109800 bp in B. graminis f. sp. tritici to 332165 bp in G. cichoracearum, which is the largest mitochondrial genome of a fungal pathogen reported to date. Further comparative analysis revealed an unusual bimodal GC distribution in the mitochondrial genomes of B. graminis f. sp. tritici and G. cichoracearum that was not previously observed in fungi. The cytochrome b (cob) genes of E. necator, E. pisi, and G. cichoracearum were also exceptionally rich in introns, which in turn harboured rare open reading frames encoding reverse transcriptases that were likely acquired horizontally. Golovinomyces cichoracearum had also the longest cob gene (45 kb) among 703 fungal cob genes analysed. Collectively, these results provide novel insights into the organization of mitochondrial genomes of powdery mildew pathogens and represent valuable resources for population genetics and evolutionary studies.

Approximately 33 types of commonly consumed fruits and vegetables are members of the Cucurbitaceae, making it an important crop family worldwide. However, pathogen resistance to pesticides/fungicides has become a growing problem in cultivation practices. The identification of the effector proteins in each unique fungus–host pair would help toward the development of strategies for preventing the infection of important crops. In this study, we characterized the genome of Podosphaera xanthii, the fungal pathogen that causes powdery mildew disease in Cucurbitaceous plants. A first-draft genome of 209.08 MB was assembled and compared with those of 25 other fungal pathogens, particularly for identifying candidate secreted effector proteins. This draft genome can serve as a valuable resource for future genomic/proteomic studies of P. xanthii and its host-specific pathogenesis.
