Abstract

Handroanthus serratifolius (yellow lapacho) and Tabebuia rosea (pink poui) are forest species of ecological and economic importance in Brazil. In March 2023, leaves exhibiting target spot symptoms were collected from a forest nursery in São Lourenço da Mata, Pernambuco, Brazil. Fungal isolates were obtained and purified from the symptomatic tissue. Based on morphological characterization, multilocus phylogenetic analysis (ITS, TEF-1α, TUB2 and LSU), and pathogenicity tests, the causal agent was identified as Corynespora cassiicola. This represents the first confirmed global report of C. cassiicola infecting H. serratifolius and T. rosea supported by molecular phylogeny.

巴西细刺蕨和玫瑰花椒靶叶斑病的首次证实报告

在巴西，Handroanthus serratifolius（黄色lapacho）和Tabebuia rosea（粉红色poui）是具有重要生态和经济意义的森林物种。2023年3月，从巴西伯南布哥州 o loureno da Mata的一个森林苗圃收集了表现出目标斑点症状的叶子。从有症状的组织中分离并纯化真菌。经形态学鉴定、ITS、TEF-1α、TUB2和LSU多位点系统发育分析和致病性检测，确定病原菌为cassiicola Corynespora。这是全球首次得到分子系统发育学支持的卡氏杆菌感染锯齿形嗜血杆菌和玫瑰红嗜血杆菌的报告。

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.
