| Popis: | Stems of red-fleshed dragon fruit (Hylocereus polyrhizus) with reddish brown spots were collected from Negeri Sembilan and Johor in Malaysia. Based on morphological and molecular characteristics, the fungi isolated from the stems were identified as Nigrospora lacticolonia and N. sphaerica. Phylogenetic analysis of internal transcribed spacer (ITS) region, β-tubulin and translation elongation factor 1-α (TEF1-α) genes confirmed the species identification. The fungal isolates produced reddish brown spot on the inoculated stems. This is the first report of N. lacticolonia and N. sphaerica as the pathogens of dragon fruit plant in Malaysia. |
