摘要

摘要新冠黄是一种多年生开花植物，具有观赏、营养和药用价值。2019年10月，在中国云南省的H.coronarium田地中观察到根腐症状。从患病样品中获得真菌分离株，并通过使用受伤和未受伤的植物接种满足Koch的假设来确认致病性。通过形态学鉴定、吻合分组以及rDNA ITS和EF-1α的序列分析，确定该病原体为Ceratobasidium sp.（双核丝核菌）。据我们所知，这是首次报道Ceratobasidium sp.AG-I（双核丝核菌）引起H.coronarium根腐病。

First report of Ceratobasidium sp. AG-I (binucleate Rhizoctonia) causing root rot of Hedychium coronarium Koen in China

Abstract Hedychium coronarium Koen is a perennial flowering plant that has ornamental, nutritional and medicinal value. In October 2019, root rot symptoms were observed in fields of H. coronarium in Yunnan Province, China. Fungal isolates were obtained from the diseased samples and the pathogenicity was confirmed by fulfilling Koch’s postulates using wounded and unwounded plant inoculations. The pathogen was identified as Ceratobasidium sp. (binucleate Rhizoctonia) through morphological characterization and anastomosis grouping as well as sequence analysis of both rDNA-ITS and EF-1α. To our knowledge, this is the first report of Ceratobasidium sp. AG-I (binucleate Rhizoctonia) causing root rot on H. coronarium.

期刊介绍： Canadian Journal of Plant Pathology is an international journal which publishes the results of scientific research and other information relevant to the discipline of plant pathology as review papers, research articles, notes and disease reports. Papers may be submitted in English or French and are subject to peer review. Research articles and notes include original research that contributes to the science of plant pathology or to the practice of plant pathology, including the diagnosis, estimation, prevention, and control of plant diseases. Notes are generally shorter in length and include more concise research results. Disease reports are brief, previously unpublished accounts of diseases occurring on a new host or geographic region. Review papers include mini-reviews, descriptions of emerging technologies, and full reviews on a topic of interest to readers, including symposium papers. These papers will be highlighted in each issue of the journal and require prior discussion with the Editor-in-Chief prior to submission.
