Peronosporaceae Species Causing Downy Mildew Diseases of Poaceae, Including Nomenclature Revisions and Diagnostic Resources

Abstract: Downy mildew pathogens of graminicolous hosts (Poaceae) are members of eight morphologically and phylogenetically distinct genera in the Peronosporaceae (Oomycota, Peronosporales). Graminicolous downy mildews (GDMs) cause severe losses in crops such as maize, millets, sorghum, and sugarcane in many parts of the world, especially in tropical climates. In countries where the most destructive GDMs are not endemic, these organisms are often designated as high-risk foreign pathogens and subject to oversight and qua… Show more

“…within these six clades. Synteny with the complete genome of P. effusa was used to validate the derived chromosome-scale genome architectures of the DMP, Peronosclerospora sorghi (38), and the clade 5 hemibiotroph Phytophthora agathidicida (19). The extent of synteny with more diverse oomycetes, such as Phytophthora spp.…”

“…that have broad host ranges (52,79,127). Exceptions exist; for example, graminicolous DMPs are reported to be pathogenic on a wide variety of Poaceae (19,128). Also, the DMP Pseudoperonospora cubensis is pathogenic on more than 50 cucurbit species (106,111).…”

“…Functionally, the synchronous production and ripening of up to more than 100 caducous sporangia per candelabra-like sporangiophore apex in S. medusiformis resembles 19 of the 20 DM genera [4,119,120,123,[125][126][127], allowing simultaneous aerial spread with high inoculum pressure. Another similarity between Synchrospora and the DMs is the small size (and hence weight) of the sporangia increasing their aerial dispersibility, whereas the unusually long, curved and twisted pedicels most likely facilitate sporangial clustering and adherence to plant surfaces as recently suggested for aerial long-pedicellate Phytophthora species [16].…”

“…Moreover, in several DM genera, the determinate sporangiophores also have dilated apices on which multiple sporangia or conidia are produced. These apices are saucer-shaped in Bremia, club-shaped in Eraphthora, cone-to club-shaped in Basidiophora and broad club-shaped to cylindrical in Baobabopsis [120][121][122][123]. However, none of the known DM genera form multifurcated candelabra-like sporangiophore apices.…”
