Detection of double-stranded RNA molecules and virus-like particles in different Mucor species.
The presence of double-stranded RNA elements was examined in 123 strains representing 18 Mucor species. These genetic elements were found to be present in 6 strains: 1 M. aligarensis, 1 M. hiemalis, 2 M. corticolus, 1 M. mucedo and 1 M. ramannianus. Electrophoretic separation of the nucleic acids revealed 4 different RNA patterns, with 1 to 5 discrete dsRNA bands. The molecular weights corresponding to these bands were 1.42-4.15 x 10(6) D. Using electronmicroscopy, for the first time the presence of virus like particles in Mucor species has been revealed.
