Abstract

Curvularia americana and C. tropicalis are described as causes of leaf and crown necroses on Bermuda grass (Cynodon dactylon x Cynodon transvaalensis) in Veneto, Northern Italy. These pathogens were characterized using morphological characters, and a multilocus molecular phylogenetic analysis based on the nuclear ribosomal internal transcribed spacer (ITS) region, the partial glyceraldehyde-3-phosphate dehydrogenase (gapdh) and translation elongation factor-1α (tef1-α) genes. Pathogenicity tests and the fulfilment of Koch’s postulates confirmed C. americana and C. tropicalis as foliar pathogens of Bermuda grass. This is the first report of C. americana and C. tropicalis as pathogens of Bermuda grass, and the first record these two fungi in Europe.

美洲弯孢菌和热带弯孢菌导致意大利百慕大草叶片和树冠坏死

美洲弯孢菌和热带弯孢菌被描述为意大利北部威尼托百慕大草（犬齿龙x叉齿龙）叶片和树冠坏死的原因。利用形态学特征和基于核核糖体内部转录间隔区（ITS）、部分甘油醛-3-磷酸脱氢酶（gapdh）和翻译延伸因子-1α（tef1-α）基因的多点分子系统发育分析对这些病原体进行了表征。致病性测试和Koch假设的实现证实了美洲C.americana和热带C.tropicalis是百慕大草的叶片病原体。这是美洲锥虫和热带锥虫作为百慕大草病原体的首次报道，也是欧洲首次记录这两种真菌。

期刊介绍： Phytopathologia Mediterranea is an international journal edited by the Mediterranean Phytopathological Union. The journal’s mission is the promotion of plant health for Mediterranean crops, climate and regions, safe food production, and the transfer of new knowledge on plant diseases and their sustainable management. The journal deals with all areas of plant pathology, including etiology, epidemiology, disease control, biochemical and physiological aspects, and utilization of molecular technologies. All types of plant pathogens are covered, including fungi, oomycetes, nematodes, protozoa, bacteria, phytoplasmas, viruses, and viroids. The journal also gives a special attention to research on mycotoxins, biological and integrated management of plant diseases, and the use of natural substances in disease and weed control. The journal focuses on pathology of Mediterranean crops grown throughout the world. The Editorial Board of Phytopathologia Mediterranea has recently been reorganised, under two Editors-in-Chief and with an increased number of editors.
