Cassava mosaic disease (CMD) caused by African cassava mosaic virus (ACMV) and East African cassava mosaic Cameroon virus (EACMCV) is the major constraint to cassava production in Nigeria. Sequences of the DNA-A component of ACMV and EACMCV isolates from leguminous plant species (Senna occidental...

African cassava mosaic virus (ACMV; genus Begomovirus, family Geminiviridae) is one of six viruses documented in cassava (Manihot esculenta Crantz.) plants showing cassava mosaic disease in sub-Saharan Africa (SSA). In addition to cassava, the natural host range of ACMV includes a few wild Maniho...

Helicoverpa armigera nucleopolyhedrovirus (HaNPV, Family: Baculoviridae; Genus: Nucleopolyhedrovirus) is a natural pathogen of Helicoverpa armigera (Insecta: Arthropoda) larvae and has proven to be a good candidate for the biocontrol of this pest on legume crops. In this study various immunochemi...

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...

Polymerase chain reaction (PCR)-based applications in plant molecular biology and molecular diagnostics for plant pathogens require good quality DNA for reliable and reproducible results. Leaf tissue is often the choice for DNA extraction, but the use of other sources such as tubers, stems, or se...

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...

Many Nigerian farmers depend for their seed on seed-producing farmers, the so-called informal Seed System (SS), but seed quality of the SS is unknown. Farmers planting low quality seed risk poor field emergence and low plant vigour as a result of low physiological quality or infection with seed-b...
