A survey was conducted in major yam cultivation zones in Côte d’Ivoire in 2009 to determine the incidence, severity of viral diseases, and viruses associated with the infected plants. Incidence and severity of the viral diseases were estimated based on symptoms. Enzyme-linked immunosorbent assay ...

Most smallholder farmers in developing countries depend on an informal Seed System (SS) for their seed. The informal SS is often criticized because farmer-produced seed samples are not tested for seed health, thus accepting the risk of planting infected seeds. Here we aimed at assessing the quali...

Aflatoxin B1 is a carcinogen produced by Aspergillus flavus and a few related fungi that are often presentin many food substances. It interacts synergistically with Hepatitis B or C virus (HBV, HBC) infection,thereby increasing the risk of hepatocellular carcinoma (HCC). The G to T transversion a...

To date, several viruses of different genera have been reported to infect yam (Dioscorea spp.). The full diversity of viruses infecting yam, however, remains to be explored. High-throughput sequencing (HTS) methods are increasingly being used in the discovery of new plant viral genomes. In this s...

Vegetatively propagated crops, suffer from yield loss and reduced stand density and longevity caused by the buildup of certain pests and pathogens between successive plantings via via infected planting material. We reviewed six seed‐borne phytosanitary problems to evaluate whether a seed degenera...

Water yam (Dioscorea alata L.) is one of the most important food yams with wide geographical distribution in tropics. One of the major constraints to water yam production is anthracnose disease caused by a fungus, Colletotrichum gloesporioides (Penz.). There are no economically feasible solutions...

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...
