摘要

西瓜（Citrullus lanatus）是巴西重要的出口作物，具有重要的经济价值。2019年11月，在北里约热内卢Grande do north的商业田里观察到西瓜植株出现根腐病和藤蔓下降的症状。对有症状植株的根片段进行消毒，在马铃薯葡萄糖琼脂上培养，鉴定为Macrophomina spp. DNA分析证实为大戟芽孢杆菌（M. euphorbiicola）。接种植株的致病性试验显示出严重的症状。这是世界上第一个关于大戟分枝杆菌引起西瓜根腐病的报道，突出了这种疾病的重要性。

First Worldwide Report of Macrophomina euphorbiicola Causing Root Rot on Citrullus lanatus in Brazil

Watermelon (Citrullus lanatus) is a key export crop for Brazil with substantial economic value. In November 2019, watermelon plants displaying symptoms of root rot and vine decline were observed in commercial fields in Rio Grande do Norte. Root fragments from symptomatic plants were disinfected, cultured on potato dextrose agar and identified as Macrophomina spp. DNA analysis confirmed the species as M. euphorbiicola. Pathogenicity tests showed severe symptoms in inoculated plants. This is the first worldwide report of M. euphorbiicola causing root rot in watermelon, highlighting the disease's significance.

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.
