“…Moreover, Lombard et al [18] identified fifteen cryptic taxa using five gene regions in the Fusarium. Multi-genes analysis, such as ITS, IGS rDNA (the nuclear ribosomal intergenic spacer region), mating-type genes (mat1-1-1α-box), tef1 and tub2, are used to delineate species in Fusarium and beyond species level within the F. oxysporum species complex [2,20,[22][23][24]. In this study, we combined morphological characteristics with DNA sequence analysis of rpb2, tef1 and tub2 genes to ensure species identification accurately.…”

Fusarium elaeidis Causes Stem and Root Rot on Alocasia longiloba in South China

et al. 2021

Alocasia longiloba is a popular ornamental plant in China, however pests and diseases associated with A. longiloba reduce the ornamental value of this plant. From 2016 to 2021, stem and root rot has been observed on A. longiloba in Guangdong Province, China. Once the disease became severe, plants wilted and died. A fungus was isolated from the diseased stem and identified as Fusarium elaeidis using both morphological characteristics and molecular analysis of DNA-directed RNA polymerase II subunit (rpb2), translation elongation factor-1α (tef1) gene and β-tubulin (tub2) sequence data. The pathogenicity test showed the fungus was able to produce typical symptoms on A. longiloba similar to those observed in the field. The original pathogen was reisolated from inoculated plants fulfilling Koch’s postulates. This is the first report of Fusarium elaeidis causing stem rot on A. longiloba. These results will provide a baseline to identify and control diseases associated with A. longiloba.
