A substantial impact on Africa agriculture can be made through research on crop improvement for the extensive inland valley agro-ecosystems (IVS) extending from the humid forest to the savanna zones in sub saharan Africa. Systematic surveys of farmers have shown that cassava is a favoured upland ...

For the purpose of constructing yam cDNA libraries, attempts to isolate high quality RNA using several previously reported protocols were unsuccessful. Therefore a protocol was standardized for yam total RNA isolation by using guanidium buffer at the Department of Biology, Virginia Sate Universit...
Over recent years, pest and disease epidemics have affected the reliability of the main food crops in Uganda. Attempts to improve crop diversity therefore, and reduce reliance on the key staple crops, have included the promotion of yam (Dioscorea spp.) through the introduction of improved cultiva...
