Abstract

Sophora alopecuroides is a medicinal herb with high alkaloid content that is crucial in sand fixation in northwest China. In September 2023, a leaf spot disease was detected on wild S. alopecuroides growing in semi-arid steppe in Yanchi county (Ningxia, China). Based on morphological features and tef1, gapdh and rpb2 sequence analysis, the representative isolates obtained from the leaf spots (H3 and H4) were identified as Alternaria alternata. Koch's postulates for pathogenicity tests were completed on S. alopecuroides seedlings. To our knowledge, this is the first report of A. alternata causing leaf spot on S. alopecuroides in China.

引起苦豆子叶斑病的互交线虫

苦豆子是一种生物碱含量较高的西北固沙药材。2023年9月，在宁夏盐池县半干旱草原上检测到一种野生白花葡萄叶斑病。基于形态学特征和tef1、gapdh和rpb2序列分析，从叶斑区获得的代表性分离株（H3和H4）鉴定为互花霉（Alternaria alternata）。科赫的假设的致病性测试是完成了对紫花葡萄幼苗。据我们所知，这是在中国首次报道的引起白花楸叶斑病的互生刺蚜。

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.
