Technical Abstract: Sugarcane mosaic virus (SCMV) is well known to infect several plant species of the Poaceae family, including cultivated plants and various wild grasses. Patterns of contrasting shades of green were recently observed on leaves of five plant species in South Florida: Columbus grass (Sorghum almum), maize (Zea mays), sorghum (Sorghum bicolor), St. Augustine grass (Stenotaphrum secundatum), and sugarcane (Saccharum spp.). Thirty two plants with these mosaic looking symptoms were collected and tested by reverse-transcription polymerase chain reaction (RT-PCR) using Poaceae potyvirus specific primers (oligo 1n and oligo 2n). All plants produced an amplicon of about 320-330 bp that was sequenced. Amplicons showed highest nucleotide identity with SCMV isolates in GenBank (BLASTn), thus confirming that Columbus grass, maize, sorghum, St Augustine grass, and sugarcane were hosts of the same virus species in South Florida. The genetic relationship between the virus isolates occurring in these five plant hosts is currently being investigated.
