In vitro culture offers many advantages for yam germplasm conservation, propagation and international distribution. However, low virus titres in the generated tissues pose a challenge for reliable virus detection, which makes it difficult to ensure that planting material is virus-free. In this st...

Yam mosaic virus (YMV; genus Potyvirus ) is considered to cause the most economically important viral disease of yams ( Dioscorea spp.) in West Africa which is the dominant region for yam production globally. Yams are a vegetatively propagated crop and the use of virus-free planting material form...

Pigeonpea sterility mosaic virus (PPSMV), a species of the genus Emaravirus, is the causal agent of sterility mosaic disease (SMD) of pigeonpea [Cajanus cajan (L.) Millsp]. This disease, dubbed the ‘green plague’, as the infected plants remain in the vegetative state without flower production, ha...
