Investigation on transmission modes and host range of sugarcane streak mosaic virus in sugarcane (Saccharum officinarum L.) in Indonesia
Journal Title: Journal of Agricultural and Crop Research - Year 2015, Vol 3, Issue 4
Abstract
Sugarcane streak mosaic virus (SCSMV) is a new virus of sugarcane in Indonesia. The virus was first reported in 2005 and since then it has been widely distributed across Java Island. Since SCSMV is a new emerging virus the investigation on virus aetiology including transmission modes and virus host range is required. The results of transmission study revealed that SCSMV was transmitted through cane cuttings and caused latent infection. The virus was mechanically transmitted through cutting knife and unable to be transmitted by sugarcane aphid Melanaphis sacchari. The transmissibility of SCSMV through cane cuttings and cutting tools play important role in virus distribution in the field because sugarcane is propagated vegetatively using cane cuttings and cutting tools is commonly used for seed cane preparation. The host range test showed that SCSMV infected sorghum (Sorghum bicolor), maize (Zea mays), Saccharum officinarum, Saccharum spontaneum, Saccharum robustum, Saccharum sinense, Saccharum barberi and Mischantus. Several weed grasses namely Brachiaria moniliformis, Panicum repens, Paspalum conjugatum, and Rottboelia exaltata were also infected by the virus. Those plants are alternative hosts of the virus and could be the favourable environment for virus survival particularly when the sugarcane plants have been harvested.
