Different aspects on the history, screening, and domestication effect on the evolution of the bean species are discussed, based on the concept of species domestication. Data are examined on plant systematics and geography, etnological botany, biochemistry, arqueology, and genetics of the crop. Th...

Information is presented on the frequency of the Msp I (-) allele in the third intron of the bovine growth hormone gene in a large number of cattle breeds. Consideration of the breed frequencies in relation to their geographic origin shows a low frequency for breeds originating in Northern Europe...

The tick vectors of heartwater (Cowdria ruminantium infection) in Zimbabwe, Amblyomma hebraeum and Amblyomma variegatum, historically were believed to be confined to the low-lying regions of the south and north-west of the country. However, country-wide surveys performed in 1975-1980 and 1988-199...

The extent of 5S and 45S ribosomal DNA (rDNA) variation was investigated in wild and domesticated common beans (Phaseolus vulgaris) chosen to represent the known genetic diversity of the species. 5S and 45S rDNA probes were localized on mitotic chromosomes of 37 accessions by fluorescent in situ ...

Isolates of Pseudomonas syringae pv. phaseolicola from Africa and other bean growing areas were categorized into nine races on the basis of their reactions to eight differential cultivars following artificial inoculation. Eight hundred and ninety-three isolates representing 303 disease occurrence...

This overview aims at browsing the scene of action for research on the resistance of small ruminant to endoparasites in sub-Saharan Africa. After recalling the main sheep and goat breeds, it describes the geographic distribution of these populations in the continent, mentions the farming systems ...
