Interpretive Summary:

Technical Abstract: Sugarcane mosaic virus (SCMV) is known to infect several 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 symptoms were collected and tested by reverse-transcription polymerase chain reaction (RT-PCR) using Poaceae potyvirus specific primers (oligo 1n and oligo 2n). An amplicon of 320-330 bp was generated from every sample. These were subsequently sequenced, revealing highest nucleotide identities with SCMV isolates. This confirms that Columbus grass, maize, sorghum, St Augustine grass, and sugarcane are hosts of the same virus species in South Florida. The genetic relationships among the virus isolates occurring in these five plant hosts is currently being investigated.
