Genetic diversity of selected Moringa oleifera lam. Provenances from the coastal region of Kenya

Sarah Kwamboka Ondieki, H. W., Geoffrey M. Muluvi, Jackson C. Korir et autres

Moringa oleifera Lam (syn. M. Pterygosperma Gaertn) is one of the most economically important crops widely cultivated globally. Traditionally, it has been used as a remedy for conditions such as diabetes, inflammation, cancer, bacterial, viral, and fungal infections, joint pain and heart …

Genetic diversity and relationship between wild and cultivated cowpea [ Vigna unguiculata (L.) Walp.] as assessed by allozyme markers

Eric Bertrand Kouam, Geoffrey M. Muluvi, Rémy Pasquet

Abstract In Cameroon, cowpea plays an important role in traditional agroecosystems. Genetic variation in wild and cultivated cowpea in Cameroon has not yet been documented. Allozyme markers because of their codominance and polymorphism are useful tools for studying genetic variation and disparity …

Distribution of indigenous strains of atoxigenic and toxigenic Aspergillus flavus and Aspergillus parasiticus in maize and peanuts agro-ecological zones of Kenya

Daniel Okun, Fathiya M. Khamis, Geoffrey M. Muluvi, Joseph Ngeranwa et autres

Grains of important food and export crops in Africa are susceptible to contamination by toxin-producing moulds. Aflatoxins are mycotoxins associated with liver damage and cancer in humans and animals. These toxic substances are produced by fungi (such as Aspergillus flavus and Aspergillus …

Assessment of the genetic diversity and pattern of relationship of West African sorghum accessions using microsatellite markers

Min Nie, K. Kiambi D., B. Haussman, Kassa Semagn et autres

An understanding of the extent, distribution and patterns of genetic variation is useful for estimation of any possible loss of genetic diversity and assessment of genetic variability and its potential use in breeding programs, including establishment of heterotic groups. This study assessed …

Mapping of quantitative trait loci for floral scent compounds in cowpea ( V igna unguiculata L.)

Mebeaselassie Andargie, Jette T. Knudsen, Rémy Pasquet, Bhavani Shankara Gowda et autres

Abstract Floral scent is a very important trait in plant evolution. Currently, little is known about the inheritance of floral scent in cowpea (Vigna unguiculata L.) or changes that might have occurred during its domestication. Therefore, we analysed scent volatiles and molecular …

Quantitative trait loci analysis of flowering time related traits identified in recombinant inbred lines of cowpea (Vigna unguiculata)

Mebeasealassie Andargie, Rémy Pasquet, Geoffrey M. Muluvi, Michael P. Timko

Flowering time is a major adaptive trait in plants and an important selection criterion in the breeding for genetic improvement of crop species. QTLs for the time of flower opening and days to flower were identified in a cross between a short …

Divergent pattern of nuclear genetic diversity across the range of the Afromontane Prunus africana mirrors variable climate of African highlands

C. A. C. Kadu, Heino Konrad, Silvio Schueler, Geoffrey M. Muluvi et autres

BACKGROUND AND AIMS: Afromontane forest ecosystems share a high similarity of plant and animal biodiversity, although they occur mainly on isolated mountain massifs throughout the continent. This resemblance has long provoked questions on former wider distribution of Afromontane forests. In this study …

Genetic Variation of Kenyan Populations of Warburgia ugandensis, an Important East African Highlands Medicinal Tree Species

Alice Muchugi, Roland Kindt, Geoffrey M. Muluvi, Edward Muge et autres

Warburgia ugandensis is an important medicinal tree species in Eastern Africa used to treat several ailments. Wild populations are under great threat due to unsustainable harvesting for medicines and indiscriminate felling of trees for timber and firewood. There is an urgent need …

Genetic structure and mating system of wild cowpea populations in West Africa

Eric Bertrand Kouam, Rémy Pasquet, Pascal Campagne, Jean-Baptiste Tignegre et autres

BACKGROUND: Cowpea is a highly inbred crop. It is part of a crop-weed complex, whose origin and dynamics is unknown, which is distributed across the African continent. This study examined outcrossing rates and genetic structures in 35 wild cowpea (Vigna unguiculata ssp. …
