摘要

西瓜在巴西种植，用于国内消费和出口。2022年3月，在巴西北部大德州阿波迪（Apodi）的一块商业田里采集了无症状西瓜果实。将果实放置在潮湿的室内，从花序梗中分离出真菌分离株。对分离株进行分离纯化，并结合形态学检查、TEF-1α和RPB2序列数据进行系统发育分析和致病性试验，确定病原菌为pernambucanum。这是世界上第一个关于pernambucanum引起西瓜采后果实腐烂的报告。

First Worldwide Report of Fusarium pernambucanum Causing Postharvest Fruit Rot on Citrullus lanatus

Watermelon is grown in Brazil for domestic consumption and export. In March 2022, asymptomatic watermelon fruits were collected in a commercial field located in Apodi, Rio Grande do Norte, Brazil. Fruits were placed in a humid chamber, and the fungal isolates were isolated from the peduncle. The isolates were purified, and through a combination of morphological examinations, phylogenetic analysis using TEF-1α and RPB2 sequence data, and pathogenicity tests, the causal agent was identified as Fusarium pernambucanum. This is the first worldwide report of F. pernambucanum causing postharvest fruit rot in watermelon.

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.
