Unlocking factors, temporal trends, and management strategies for viral diseases in Cameroonian yams (Dioscorea spp.) germplasms

Plant Trends
Viral disease poses a major threat to yams (Dioscorea spp.) cultivation in sub-Saharan Africa. Therefore, the aim of this study was to conduct a comprehensive analysis of incidence, climate impacts, role of vectors, and temporal trends of yam viral ...

The prevalence of badnaviruses in West African yams (Dioscorea cayenensis-rotundata) and evidence of endogenous pararetrovirus sequences in their genomes [PDF]

, 2014
Yam (Dioscorea spp.) is an important vegetatively-propagated staple crop in West Africa. Viruses are pervasive in yam worldwide, decreasing growth and yield, as well as hindering the international movement of germplasm. Badnaviruses have been reported to

Evolution of functional properties of precocious yam starch (Dioscorea cayenensis-rotundata) during tuberization

International Journal of Biological and Chemical Sciences, 2008
The behaviour of starch during tuberization was carried out in order to determine the appropriate yam starch properties for industrial applications. Starch was isolated from “Kponan” variety of Dioscorea cayenensis-rotundata and submitted to functional properties study.
