Abstract
A method of producing a rotavirus-like particle (RLP) in a plant is provided. The method comprises expressing within a host or host cell for example a plant, portion of a plant or plant cell one or more nucleic acid comprising one or more regulatory region operatively linked to a first, second and third nucleotide sequence, the regulatory region active in the host or host cell. The first nucleotide sequence encoding a first rotavirus protein, the second nucleotide sequence encoding a second rotavirus protein and the third nucleotide sequence encoding a third rotavirus protein. The first, second and third encode rotavirus protein NSP4 and VP2 or VP6 and VP4 or VP7. The host or host cell is incubated under conditions that permit the expression of the nucleic acids, so that NSP4 and either VP2 of VP6 and VP4 or VP7 are expressed, thereby producing the RLP. Hosts comprising the RLP, compositions comprising the RLP and method for using the composition are also provided.
