Abstract excerpt

Since the first report of stem and fruit canker in 2012, Neoscytalidium dimidiatum has become a major pathogen affecting dragon fruit (Hylocereus spp.) production areas in Taiwan. To investigate the spatiotemporal genetic structure and the mode of reproduction of this emerging pathogen, 11 simple sequence repeat markers were developed to genotype 244 isolates, including 225 from dragon fruit, 11 from cattleya...
