M.Siriwan, WanwisaSzyniszewska, AnnaTumwegamire, SilverWinter, StephanKumar, P.L.[Mitigating Cassava Virus Pandemics in an increasingly Connected Global Environment: Lessons from the last 30 Years]Mitigating Cassava Virus Pandemics in an increasingly Connected Global Environment: Lessons from the last 30 Years

Cassava is the most important root and tuber crop in Sierra Leone. Its low yield can be attributed to several production-limiting factors including cassava mosaic disease (CMD). This study examined in a much wider scope the diversity, prevalence, distribution, incidence and level of severity of t...

Uniplex and multiplex reverse transcription-polymerase chain reaction (RT-PCR) protocols were developed for the detection of cassava brown streak viruses (CBSVs) in single and mixed infections with cassava mosaic begomoviruses (CMBs) in a tropical crop plant, cassava (Manihot esculenta). CMBs con...


Abarshi, M.M.Mohammed, I.Jeremiah, S.C.Legg, J.P.Kumar, P.L.Hillocks, R.J.Maruthi, M.N.[Multiplex RTPCR assays for the simultaneous detection of both RNA and DNA viruses infecting cassava and the common occurrence of mixed infections by two cassava brown streak viruses in East Africa]Multiplex RTPCR assays for the simultaneous detection of both RNA and DNA viruses infecting cassava and the common occurrence of mixed infections by two cassava brown streak viruses in East Africa

Aims: To develop a multiplex TaqMan-based real-time PCR assay (qPCR) for the simultaneous detection and quantification of both RNA and DNA viruses affecting cassava (Manihot esculenta) in eastern Africa. Methods and Results: The diagnostic assay was developed for two RNA viruses; Cassava brown st...

The whitefy Bemisia tabaci, a species complex consisting of many morphologically indistinguishable species divided into distinct clades, is one of the most globally important agricultural pests and plant virus vectors. Cassava-colonizing B. tabaci transmits viruses that cause cassava mosaic disea...

Cassava 'brown streak' disease (CBSD) is an economically important constraint in important cassava-growing areas of East, Central and Southern Africa. In addition to causing a dry necrotic rot in the tuberous roots of infected plants, which can render them inedible, CBSD depresses yields through ...

Cassava mosaic disease (CMD) caused by the whitefly-transmitted begomoviruses (family Geminiviridae) is amajor threat to production of cassava (Manihot esculenta Crantz) in Côte d’Ivoire. A survey was conducted in themajor production zones in Côte d’Ivoire to assess the incidence, severity, and d...
