　　Hibiscus latent Singapore virus (-HLSV) is a rigid rod shaped plant virus, a new member of the Tobamovirus family.Unlike all other Tobamoviruses, the HLSV genome contains a unique poly(A) tract in its 3-UTR.The virion is composed of a monomeric coat protein (CP) unit of 18 kDa, arranged as a right handed helix around the virus axis.We have determined the structure of HLSV at 3.5 A by X-ray fiber diffraction and refined it to an R-factor of 0.096.
