AbstractGrape hyacinths (Muscari spp.) are popular spring flowering bulbs in Europe and also in Hungary. In the spring of 2017, we came across grape hyacinth plants showing mosaic symptoms, which indicated viral infection. Currently Hyacinth mosaic virus (genus Potyvirus), a proposed member of the genus named Muscari mosaic virus, Arabis mosaic virus (genus Nepovirus), Cucumber mosaic virus (genus Cucumovirus) and Tobacco rattle virus (genus Tobravirus) are known to infect grape hyacinth. Leaf samples of symptomatic grape hyacinths were observed, collected and the presence of potyviruses was proved with potyvirus specific monoclonal antibody by ELISA and by potyvirus specific RT-PCR. Laboratory host plants and seed grown Muscari plants were inoculated with leaf sap and symptoms were recorded. Nucleotide sequences of the cloned fragments were compared to GenBank data. In the case of Muscari ‘Helena’ the highest nucleotide identity in the coat protein coding region was found with two Muscari mosaic virus isolates (95.51% and 95.79%). In the case of the clones derived from Muscari ‘Pink Sunrise’ plant, the highest identity was recorded with Muscari mosaic virus isolates (57.65% and 57.80%) and with a Tulip breaking virus strain (55.13%) indicating the existence of a novel potyvirus species, tentatively named Muscari chlorotic mottle virus. The coat protein sequences were aligned and Maximum Likelihood trees were built to analyze phylogenetic relationships.

Sugarcane mosaic virus (SCMV) was detected by reverse-transcription polymerase chain reaction in eight different species of the Poaceae family in the Everglades Agricultural Area (EAA) of south Florida: Broadleaf signalgrass (Urochloa platyphylla), Columbus grass (Sorghum almum), goosegrass (Eleusine indica), maize (Zea mays), sorghum (Sorghum bicolor), St. Augustine grass (Stenotaphrum secundatum), southern crabgrass (Digitaria ciliaris), and sugarcane (Saccharum interspecific hybrids). Based on their coat protein (CP) gene sequence, 62 isolates of SCMV from Florida and 29 worldwide isolates representing the known genetic diversity of this virus were distributed into eight major phylogenetic groups. SCMV isolates infecting Columbus grass, maize, and sorghum in Florida formed a unique group whereas virus isolates infecting sugarcane in the USA (Florida and Louisiana) clustered with isolates from other countries. Based on the entire genome coding region, SCMV isolates infecting sugarcane in Florida were closest to virus isolates infecting sorghum species or St. Augustine grass. Virus isolates from Columbus grass, St. Augustine grass, and sugarcane showed different virulence patterns after mechanical inoculation of Columbus grass, St. Augustine grass, and sugarcane plants, thus proving that these isolates were different pathogenic strains. Sugarcane was symptomless and tested negative for SCMV by tissue blot immunoassay after inoculation with crude sap from SCMV-infected Columbus grass, indicating that Columbus grass was not a reservoir for SCMV infecting sugarcane in the EAA. Close CP sequence identity between isolates of SCMV from Columbus grass, maize, and sorghum suggested that the same virus strain was naturally spreading among these three plants in south Florida.
