Abstract

Ficus tikoua can be used as resources for fruit and herbal medicine inspiring large-scale planting in China. Nodular galls were found on the roots of the planted F. tikoua individuals in 2022. The mature females and egg masses of nematodes were extracted from the nodular galls, and microscopic examination suggested Meloidogyne infection. Molecular identification based on ITS, 18S rRNA sequences assigned the infecting species to Meloidogyne incognita, which was further demonstrated by the successful application of specific SCAR marker M. incognita in all samples. The pathogenicity of M. incognita was conducted on F. tikoua cutting seedlings based on Koch's postulates. This is the first report of M. incognita infection in F. tikoua in China.

中国首次报告根结线虫 Meloidogyne incognita 感染榕树的情况

榕树可作为水果和中药材资源，启发了中国的大规模种植。2022 年，在种植的榕树个体根部发现了节瘿。从结节虫瘿中提取了线虫的成熟雌虫和卵块，显微镜检查表明线虫感染。基于 ITS 和 18S rRNA 序列的分子鉴定结果表明，感染物种为 Meloidogyne incognita，在所有样本中成功应用特异性 SCAR 标记 M. incognita 进一步证明了这一点。根据科赫假说，在 F. tikoua 切苗上研究了 M. incognita 的致病性。这是中国首次报道 F. tikoua 感染 M. incognita。

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.
