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

Muluvi, Geoffrey M.; Kitavi, M. N.; Kiambi, D. K.; Haussman, B.; Semagn, K.; Kairichi, M.; Machuka, J. (Academic Journals, 2014-04)

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 ...
Big fish, little divergence: phylogeography of Lake Tanganyika’s giant cichlid, Boulengerochromis microlepis

Koblmüller, Stephan; Odhiambo, Elizabeth A.; Sinyinza, Danny; Sturmbauer, Christian; Sefc, Kristina M. (Springer Verlag, 2015-04)

The largely endemic cichlid species flocks of the East African Great Lakes are among the prime examples for explosive speciation and adaptive radiation. Speciation rates differ among cichlid lineages, and the propensity ...
Genetic analyses of ancient tea trees provide insights into the breeding history and dissemination of Chinese Assam tea (Camellia sinensis var. assamica)

Li, Miao-Miao; Meegahakumbura, Muditha K.; Wambulwa, Moses C.; Burgess, Kevin S.; Moller, Michael; Shen, Zong-Fang; Li, De-Zhu; Gao, Lian-Ming (Elsevier, 2024-03)

Chinese Assam tea (Camellia sinensis var. assamica) is an important tea crop with a long history of cultivation in Yunnan, China. Despite its potential value as a genetic resource, its genetic diversity and domestication/breeding ...
Genetic characterization and diversity of Rhizobium isolated from root nodules of mid-altitude climbing bean (Phaseolus vulgaris L.) varieties

Koskey, Gilbert; Simon, Mburu W.; Kimiti, Jacinta M.; Ombori, Omwoyo; Maingi, John M.; Njeru, Ezekiel M. (Frontiers Media, 2018)

The increasing interest in the use of rhizobia as biofertilizers in smallholder agricultural farming systems of the Sub-Saharan Africa has prompted the identification of a large number of tropical rhizobia strains and led ...
Genetic diversity and population structure of Vigna unguiculata ssp. unguiculata var. spontanea in Sudan

Muluvi, Geoffrey M.; Kouam, E. B.; Pasquet, R. S.; Elteraifi, I (Ficus, 2011)

Enzyme electrophoresis was used to estimate the genetic diversity and population structure of thirteen Vigna unguiculata ssp. unguiculata var. spontanea populations in Sudan. Plant genotypes were homozygous at most loci ...
Genetic diversity of indigenous Bradyrhizobium nodulating promiscuous soybean [Glycine max (L) Merr.] varieties in Kenya: Impact of phosphorus and lime fertilization in two contrasting sites

Wasike, V. W.; Lesueur, D.; Wachira, Francis N.; Mungai, N. W.; Mumera, L. M.; Sanginga, N.; Mburu, H. N.; Mugadi, D.; Wango, P.; Vanlauwe, B. (Springer Verlag, 2009-09)

While soybean is an exotic crop introduced in Kenya early last century, promiscuous (TGx) varieties which nodulate with indigenous rhizobia have only recently been introduced. Since farmers in Kenya generally cannot afford ...
Genetic imprints of grafting in wild iron walnut populations in southwestern China

Liu, Jie; Magige, Ephie A.; Fan, Peng‑Zhen; Wambulwa, Moses C.; Luo, Ya‑Huang; Qi, Hai‑Ling; Gao, Lian‑Ming; Milne, Richard I. (BMC, 2023-09-13)

Background: Anthropogenic activities are causing unprecedented loss of genetic diversity in many species. However, the efects on genetic diversity from large-scale grafting onto wild plants of crop species are largely ...

Liu, Jie; Magige, Ephie A.; Peng-Zhen, Fan; Wambulwa, Moses C.; Ya-Huang, Luo; Hai-Ling, Qi; Lian-Ming, Gao; Milne, Richard I. (BMC, 2023-09)

Background Anthropogenic activities are causing unprecedented loss of genetic diversity in many species. However, the effects on genetic diversity from large-scale grafting onto wild plants of crop species are largely ...
Microsatellite analysis of the correlation between molecular and morphological traits in assorted maize inbred lines

Kimatu, Josphert N.; Karanja, J.; Amugune, N. O.; Ininda, J.; Danson, J. W. (2009)

The success in identifying heterosis in hybrid maize (Zea mays L.) breeding depends on the availability of reliable genetic diversity among maize inbred lines. Conventional methods of breeding have been boosted by the ...
Microsatellite typing reveals strong genetic structure of Schistosoma mansoni from localities in Kenya

Muluvi, Geoffrey M.; Agola, L. E.; Mburu, D. N.; DeJong, R. J.; Mungai, B. N.; Njagi, E. N. M.; Loker, E. S.; Mkoji, G. M. (Elsevier, 2006-11)

Genetic diversity and population structure of seven populations of Schistosoma mansoni sampled in Kenya were assessed using five microsatellite markers. The mean number of alleles per locus, expected heterozygosity in ...
Nuclear microsatellites reveal the genetic architecture and breeding history of tea germplasm of East Africa

Wambulwa, Moses C.; Meegahakumbura, M. K.; Chalo, R.; Kamunya, S.; Muchugi, A.; Xu, J. C.; Liu, J.; Li, D. Z.; Gao, L. M. (Springer Verlag, 2016-02)

Tea is the most popular non-alcoholic beverage worldwide and is one of the most important tree cash crops in East Africa. However, no comprehensive study has been carried out on the genetic structure and diversity of tea ...
Phenomic characterization of crotalaria germplasm for crop improvement

Muli, Joshua K.; Neondo, Johnstone O.; Kamau, Peter K.; Odari, Eddy; Budambula, Nancy L. (2021-03-09)

Background: Diversifcation of global food systems through exploration of traditional varieties and wild edible plant species is a focal mitigation strategy for food security worldwide. The present study determined the ...
Population genetics of the East African White-eye species complex

Mulwa, Ronald K.; Habel, Jan C.; Cox, Siobhan; Gassert, Franz; Meyer, Jobst; Lens, Luc (Springer Netherlands, 2013-10)

The Eastern Afromontane biodiversity hotspot consists of isolated mountain massifs embedded within the dry lowland savannas of East Africa and of which the peaks and ridges are covered by cloud forest remnants. These cloud ...
Quantitative variation among Kenyan populations of Acacia senegal (L.) Willd. for gum production, seed and growth traits
