Bean crops are attacked by several viruses transmitted by insects among which are: (1) the alfalfa mosaic virus (aphids); susceptibility is correlated with plant age; (2) curly top (Circulifer tenellus); the best control measure is the utitilization of resistant var.; (3) bean summer death (Orosi...

Cassava mosaic disease (CMD) is a widespread viral disease that causes high yield losses in susceptible genotypes in Sub-Saharan Africa. Effective control of CMD is beneficial and justifiable since cassava is an important source of carbohydrates for over 200 million people in most African countri...

We have recently shown that the BoLA-A18 variant haplotype (BoLA-6*01302) is more prevalent than the BoLA-A18 haplotype (BoLA-6*01301) in a sample of Holstein/Friesian cattle in Kenya. These MHC class I allelic variants differ by a single amino acid polymorphism (Glu97 to Leu97) in the peptide-bi...

During 1981, the efforts to use meristem-culture methods have continued, together with thermotherapy for recovering healthy clones. Frog skin disease was eradicated up to 100 percent in different cassava clones during various propagation cycles through the culture of small meristem tips. A routin...
