Abstract
The cause of a streak disease of pearl millet (Pennisetum glaucum), originating from Nigeria, has been attributed to a geminivirus belonging to the ‘African streak virus’ cluster. A full-length, infectious clone of the virus was obtained which was transmissible by the vectorCicadulina mbila (Naude). Analysis of the complete nucleotide sequence of the coat protein gene of this virus shows it to be most closely related to sugarcane streak virus. The possible evolutionary implications of this finding are discussed.
