摘要

在巴西巴伊亚州的桉树人工林暴发了一种新的严重疾病。子囊菌属真菌经常与该病的主要症状有关，即叶斑病，树枝溃烂，梢枯病，落叶和枯死。通过形态学特征、系统发育分析(ITS和TEF-1α基因)和对桉树的致病性试验，确定桉树伪斜口病是该疾病的病原。虽然巴西早在1998年就发现了桉树病，但这是首次报道桉树病对桉树造成严重疾病和枯死，并且我们还记录了与该病原体相关的新症状。

Outbreak of shoot blight and dieback of Eucalyptus spp., caused by Pseudoplagiostoma eucalypti in Brazil

An outbreak of a new and severe disease was observed in Eucalyptus plantations of Bahia state, Brazil. An Ascomycota fungus has been frequently associated with the main symptoms of the disease namely leaf spot, branch cankers, shoot blight, defoliation, and dieback. Based on morphological characteristics, phylogenetic analysis (ITS and TEF-1α genes), and pathogenicity test on Eucalyptus plants, Pseudoplagiostoma eucalypti was identified as the causal agent of the disease. Although P. eucalytpi has been known from in Brazil since 1998, this is the first report of it causing severe disease and die-back on Eucalyptus spp. and we also record new symptoms associated with the pathogen.

期刊介绍： This peer reviewed, highly specialized journal covers forest pathological problems occurring in any part of the world. Research and review articles, short communications and book reviews are addressed to the professional, working with forest tree diseases caused by fungi, bacteria, nematodes, viruses, and phytoplasms; their biology, morphology, and pathology; disorders arising from genetic anomalies and physical or chemical factors in the environment. Articles are published in English. Fields of interest: Forest pathology, effects of air pollution and adverse environmental conditions on trees and forest ecosystems.
