Erysiphe thuemenii causing powdery mildew on Potentilla indica in China

Abstract In August 2017, severe powdery mildew was observed on Potentilla indica in Minhe, Qinghai province, China. The identification of fungal species was performed by morphological study using an optical microscope and scanning electron microscope (SEM), supplemented by sequence analysis of the internal transcribed spacer (ITS) region of rDNA. Based on a combination of morphology, ITS sequence, and host, the powdery mildew on Potentilla indica was identified as Erysiphe thuemenii, a species belonging to the E. aquilegiae complex. This is the first report of E. thuemenii causing powdery mildew on a new host species, P. indica, in China and also worldwide.

期刊介绍： Canadian Journal of Plant Pathology is an international journal which publishes the results of scientific research and other information relevant to the discipline of plant pathology as review papers, research articles, notes and disease reports. Papers may be submitted in English or French and are subject to peer review. Research articles and notes include original research that contributes to the science of plant pathology or to the practice of plant pathology, including the diagnosis, estimation, prevention, and control of plant diseases. Notes are generally shorter in length and include more concise research results. Disease reports are brief, previously unpublished accounts of diseases occurring on a new host or geographic region. Review papers include mini-reviews, descriptions of emerging technologies, and full reviews on a topic of interest to readers, including symposium papers. These papers will be highlighted in each issue of the journal and require prior discussion with the Editor-in-Chief prior to submission.
