Background: Anthracnose (Colletotrichum gloeosporioides) is a major limiting factor in the production of yam (Dioscorea spp.) worldwide. Availability of high quality sequence information is necessary for designing molecular markers associated with resistance. However, very limited sequence inform...

Badnaviruses (family Caulimoviridae, genus Badnavirus) have emerged as serious pathogens especially affecting the cultivation of tropical crops. Badnavirus sequences can be integrated in host genomes, complicating the detection of episomal infections and the assessment of viral genetic diversity ...

The yam bean (Pachyrizhus spp) was recently introduced as a root crop with high-yield potential, considerable protein and micro-nutrient concentration to investigate its potential for food production in Rwanda. Except for Chuin types (Pachyrizhus tuberosus) which have high storage root dry matter...

Autor: Girma, G. Spillane, Charles Gedil, M.

Distinguishing yam species based on morphological traits is extremely difficult and unreliable, posing a challenge to breeders and genebank curators. Development of a molecular assay based on DNA barcoding can facilitate rapid and accurate identification of important Dioscorea species. To develop...

Identification and quantification of carotenoids from yam and cocoyam were evaluated after different processing methods. Seven carotenoids were identified by HPLC-DAD both in the raw and processed tubers. The mean carotenoids in yam, D. cayenensis was α-carotene (0.78 μg/g), 9-cis-β-carotene (0.7...

Autor: Asala, S. Alegbejo, M.D. Kashina, B.D. Banwo, O.O. Shinngu, C.P.

The presence of viruses in yam leaves and the presence of weeds in close proximity to yam fields have been shown to be associated with diminished tuber yield. But the precise role of weeds as alternative hosts of viruses infecting yam has not been systematically studied. Therefore, leaf samples o...

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...
