Abstract
In March 2024, a leaf spot disease of Clivia miniata was observed in the greenhouse of Lanzhou Jiaotong University in Lanzhou, Gansu Province, China. The symptoms initially consisted of small brown spots, which then developed into larger, round to irregular patches with a dark brown centre and chlorotic halo. Based on morphological characteristics and molecular identification using internal transcribed spacer (ITS), translation elongation factor 1α (EF-1α), RNA polymerase II second largest subunit (RPB2), and β-tubulin (TUB2) regions, the causal fungus was identified as Fusarium proliferatum. Koch's postulates were confirmed by injecting asymptomatic leaves with a conidial suspension of the fungus. F. proliferatum has been reported previously to cause sheath rot and bulb rot on C. miniata in China, but to our knowledge, this is the first report of this fungus causing leaf spot symptoms on this host.
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.
