| Abstract/Contents: | "Smutted Bermudagrass (Cynodon dactylon L.) plants with diseased spikelets and completely deformed inflorescences covered with black teliospores were collected from five locations at the borders of plantations in Kafr El-Sheikh province, Egypt, in April 2018. The fungus was isolated from infected plants and identified as Ustilago cynodontis (Passerini) Henn. based on its cultural and morphological characteristics, molecular techniques, and pathogenicity tests. Slender colonies of U. cynodontis with irregular edges were observed on potato dextrose agar (PDA) after 6 days at 28°C. The mature teliospores were examined by scanning electron microscopy. Crystal-like structures with a pyramidal shape were observed to be produced by the fungus in culture. The crystals were further examined using an energy dispersive spectroscopy system connected to the scanning electron microscope and their dimensions were measured (18 ± 2 µm × 16 ± 2 µm × 19 ± 2 µm). PCR analysis with internal transcribed spacer (ITS) specific primers yielded an amplicon that shared a 99% identity with U. cynodontis sequences in GenBank. Phylogenetic analysis indicated that the Egyptian isolate of U. cynodontis shared the greatest similarity with isolates of U. cynodontis from Ethiopia, Iran, India, United States, Mexico, Spain, and China. Inoculation of Bermudagrass with the isolated fungus resulted in symptoms of smut similar to those observed in the field. To our knowledge, this is the first report concerning the occurrence and characterization of U. cynodontis, the causal agent of Bermudagrass smut, in Egypt." |
