Abstract/Contents: | "St. Augustine decline is a disease caused by Panicum mosaic virus (PMV). PMV is found alone, or associated with a satellite virus (SPMV), and/or satellite RNAs (satRNAs). A recent survey in two locations of Texas indicated that 60% of the symptomatic PMV-infected St. Augustinegrass (Stenotaphrum secundatum) contains satRNAs, as a revealed by RNA blots. A wide array of symptoms was observed under natural field conditions, but symptoms don't appear to be correlated with the presence or absence of a specific satRNA. The symptom expression in St. Augustine decline seems to be influenced by host genotype, nutrition, and environmental conditions. Ribonuclease protection analysis (RPA) of 100 satRNA infected plants revealed a high degree of genetic variability in these satRNAs: 64% of the satRNAs showed unique RPA patterns. Different, but overlapping populations of satRNAs were found in the two locations." |
