Abstract

Ophiopogon japonicus has been extensively grown for ornamental and medicinal purpose in China. In October 2023, the leaf spot symptoms of O. japonicus were observed, which appeared as brown lesions and yellow halos on the tip of the leaves, accompanied by the occurrence of pycnidia on more mature lesions. The fungal pathogen was isolated from the infected leaves of O. japonicus, which was identified to be Botryosphaeria dothidea through morphological features and molecular analysis involving tef1-α, ITS, and tub2 genes. Pathogenicity tests were conducted by inoculating O. japonicus leaves with mycelial plugs and conidia suspensions of B. dothidea. Appearing symptoms were similar to those observed in the field. The pathogen was reisolated and identity was reaffirmed based on its morphological and molecular traits. To the best of our knowledge, this is the first report of leaf spot disease induced by B. dothidea on O. japonicus in China.

期刊介绍： Physiological and Molecular Plant Pathology provides an International forum for original research papers, reviews, and commentaries on all aspects of the molecular biology, biochemistry, physiology, histology and cytology, genetics and evolution of plant-microbe interactions. Papers on all kinds of infective pathogen, including viruses, prokaryotes, fungi, and nematodes, as well as mutualistic organisms such as Rhizobium and mycorrhyzal fungi, are acceptable as long as they have a bearing on the interaction between pathogen and plant.
