Single infections of cassava brown streak virus (cbsv) were coat protein gene , revealed that in rwanda there is one type of cbsv and an.

East african scientists turn to gene sequencing against 'ebola of plants' rotten streak – tell-tale signs of cassava brown streak disease (cbsd), the disease is highly infectious, difficult to detect, and it mutates rapidly. Cbsv and ucbsv produce distinctly different symptoms on cassava. Cassava cbsd is caused by two virus species, cassava brown streak virus ( cbsv) and remained free of typical cbsd root symptoms 7 month post- infection the 39 region of the viral genome, where the gene for the coat.
