Abstract

In the fall of 2024, desert rose plants (Adenium obesum) displaying wilt and stem rot symptoms were collected in a residential garden in the State of Tocantins, Brazil. Here, we identify the pathogen causing these symptoms on desert roses, based on its morphological and molecular characteristics. Proof of pathogenicity was also performed. Neocosmospora keratoplastica was recognised as the causal agent of wilt and stem rot in desert roses. The study represents the first record of this fungus causing disease in Adenium obesum in Brazil and worldwide.

新宇宙孢子虫引起巴西肥胖腺瘤根腐病的首次报道

在2024年秋天，在巴西Tocantins州的一个住宅花园中收集了表现出枯萎和茎腐症状的沙漠玫瑰植物（Adenium obesum）。在这里，我们根据其形态和分子特征确定了引起沙漠玫瑰这些症状的病原体。还进行了致病性证明。新宇宙孢子菌是引起沙漠玫瑰枯萎病和茎腐病的病原。该研究首次记录了这种真菌在巴西和世界范围内引起肥胖腺瘤的疾病。

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.
