摘要

自2020年4月以来，在印度北部的车前草上一直观察到白粉病。伴生真菌的显微镜检查显示了Golovinomyces属的典型形态特征。基于内部转录间隔区BLASTn相似性搜索的分子鉴定，以及使用最大似然、最大简约和贝叶斯推理方法进行的系统发育分析，证实该物种为Golovinomyces sordidus。通过接种健康植株，验证了其致病性。据我们所知，这是印度第一个被证实的由梭状芽孢杆菌引起亚洲斑蝶白粉病的报告。

First Report of Golovinomyces sordidus Causing Powdery Mildew of Plantago asiatica in India

Since April 2020, a powdery mildew disease has been consistently observed on Plantago asiatica in northern India. Microscopic examination of the associated fungus revealed morphological characteristics typical of the genus Golovinomyces. Molecular identification based on a BLASTn similarity search of the internal transcribed spacer region, along with phylogenetic analyses using maximum likelihood, maximum parsimony, and Bayesian inference methods, confirmed the species as Golovinomyces sordidus. Pathogenicity was verified through inoculation of healthy P. asiatica plants. To the best of our knowledge, this is the first confirmed report of G. sordidus causing powdery mildew on P. asiatica in India.

期刊介绍： Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays. Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes. Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
