The present invention is directed to transcription regulators and transcription regulator-like sequences of circovirus origin. As used in the specification, the circovirus group is considered to include subterranean clover stunt virus (SCSV) coconut foliar decay virus (CFDV), banana bunchy top virus (BBTV), milk-vetch dwarf virus (MDV) and faba bean necrotic yellow virus (FBNYV). The transcription regulators and transcription regulator-like sequences of the instant invention are useful in genetic engineering of plants and in particular leguminous plants such as to facilitate or control expression of foreign genes. The transcription regulators and transcription regulator-like sequences of the present invention are also useful in facilitating different levels of expression in different plant tissue types. |
