Abstract | Inc. A specimen of downy mildew on leaves of Sphagneticola trilobata found in northern Queensland was identified by a systematic approach as a novel species of Plasmopara. A new species, Plasmopara sphagneticolae, is proposed for this specimen, which differs from other species of Plasmopara by morphology, host range, and sequence data from nuclear-ribosomal DNA and mitochondrial DNA. Plasmopara sphagneticolae, together with P. halstedii, are downy mildews found on host species in the tribe Heliantheae (Asteraceae). Plasmopara halstedii causes downy mildew on Helianthus annuus, and is not present on sunflower in Australia. Phylogenetic analysis of the large subunit region of ribosomal DNA showed that P. sphagneticolae was sister to P. halstedii on sunflower. |
