Unexpectedly, all isolates from the affected area belonged to a single strain named S4ug , a strain that is different from the S4lv strain that has been prevalent in the Lake Victoria basin for the past five decades.

Interestingly, the S4ug strain is most closely related at the genomic level except ORF1 to the strain present in Madagascar S4mg , km away. The minor parent of the S4mg recombinant strain could not be detected. Molecular clock dating analysis indicated that the singular sequence of events - that associated the emergence of a new strain S4ug , a modular recombination between closely related strains S4mg and S4ug and a long distance transmission S4mg - occurred recently, within the past few decades.

This finding is at variance with the process of gradual strain dispersal and diversification over two centuries throughout Africa that was previously established.

During July , plants with leaf yellowing and mottling symptoms were observed in Uganda in a subsistence rice field northeast of Lake Victoria, close to the Nile River.

Discriminant monoclonal antibodies revealed that the samples contained RYMV serotype 4, a serotype found in eastern Africa Madagascar, Kenya, and Tanzania 2.

The nt long coat protein gene of two isolates was amplified by reverse transcriptase-polymerase chain reaction and sequenced 1. AM and AM Isolation of the Lake Victoria Region from the rest of the Tanzania by distance, physical barriers, and patchy rice cultivation explains the specificity of the strain.

Year-round growth of wild and cultivated rice around the lake ensures host continuity in time and space that facilitates spread that accounts for the homogeneity of the isolates of this area. Knowledge of the presence of RYMV in Uganda is important since rice cultivation is intensified in this country and is planned in neighboring southern Sudan.
