A close relationship between the begomoviruses infecting pepper and tomato and A. conyzoides and the detection of the same alphasatellite in them support the idea that weeds are important reservoirs for begomviruses and their satellites.

The aim of this research was to determine etiology and to carry out the first molecular characterization of the suspected begomoviral causal agent(s) and associated ssDNA satellites in tomato crops in West Africa.
Factors influencing the adoption intensity of improved yam (Dioscorea spp.) seed technology in the western highlands and high guinea savannah zones of Cameroon.
Objective : Yam ( Dioscorea spp.) is one of the staple tubers consumed by most households in West and Central African countries. It exists in many varieties and forms and could also be consumed in a…
