Somatic embryogenesis and plant regeneration from immature embryos of tropical maize (Zea mays L.) inbred lines
(2008)Somatic embryogenesis and plant regeneration was achieved from immature embryos of six maize (Zea mays L.) inbred lines (CML216, CML78, CML331, TL18, TL27 and MU25). Callus was initiated on N6 medium supplemented with ... -
Microwave Expansion of Imitation Cheese Containing Resistant Starch
(Elsevier, 2008)The objective of this study was to manufacture an imitation cheese that expands to a crispy product when heated in a microwave oven. Imitation cheese (∼18% w/w protein and 60% w/w moisture content) was formulated with ... -
Effects of Refrigerated Storage on Water Mobility and Microwave Expansion of Imitation Cheese containing Resistant Starch
(Elsevier, 2008)The effects of storage time prior to microwave heating on expansion of imitation cheese containing functional fibre was studied. Cheese was formulated to contain 60% moisture and 17.3% w/w resistant starch. Cheese samples ... -
Impact of the invader Ipomoea hildebrandtii on grass biomass, nitrogen mineralisation and determinants of its seedling establishment in Kajiado, Kenya
(African Journal of Range and Forage Science, 2008)The invasive coloniser Ipomoea hildebrandtii aggravates the problem of inadequate grass forage in Kajiado district, Kenya. To test its impact on grass biomass, nitrogen (N) mineralisation and seedling establishment, grazing ... -
Traditional strategies used by pastoralists to cope with la nina induced drought in Kajiado, Kenya
(African Journal of Science and Technology, 2008)Pastoralists traditionally relied on herd mobility to cope with drought. In the pastoral areas of Kajiado, Kenya this strategy is now threatened by increased individual land ownership as compared to communal access. Drought ... -
Competition between cultivated rice (Oryza sativa) and wild rice (Oryza punctata) in Kenya
(African Journal of Agricultural Research, 2008)This shade house study examined the effect of competition on the growth performance of cultivated (Oryza sativa) and wild (Oryza punctata) rice species in Kenya. Growth was assessed for the two ... -
Trypanosoma brucei rhodesiense transmitted by a single tsetse fly bite in vervet monkeys as a model of Human African Trypanosomiasis.
(PLOS, 2008)We have investigated the pathogenicity of tsetse (Glossina pallidipes)-transmitted cloned strains of Trypanosoma brucei rhodesiense in vervet monkeys. Tsetse flies were confirmed to have mature trypanosome infections by ... -
Efficacy of the diamidine DB75 and its prodrug DB289, against murine models of human African trypanosomiasis
(Elsevier, 2008)The choice of drugs for the treatment of sleeping sickness is extremely limited. To redress this situation, the recently synthesised diamidine, 2,5-bis(4-amidinophenyl)-furan (DB75, furamidine) and its methamidoxime prodrug, ... -
A new species of Melanochaeta from Kenya
(Verlag Ferdinand Berger & Söhne Ges.m.b.H., 2008)Melanochaeta taitensis is described as a new species from Kenya. It is distinguished from the other known species of Melanochaeta by having large, 3-septate, strongly curved ascospores. Phylogenetic analyses of nuclear 28S ... -
Two new genera in the Magnaporthaceae, a new addition to Ceratosphaeria and two new species of Lentomitella
(Taylor & Francis, 2008)Ceratosphaerella is described as a new genus for C. castillensis and C. rhizomorpha. The genus is related to Ophioceras but distinguished by ascomata with a basal stroma and shorter, fusiform ascospores. Muraeriata is ... -

Plant regeneration via somatic embryogenesis of tropical maize (Zea mays L.) commercial hybrid lines.
(Journal of Tropical Microbiology and Biotechnology, 2008)Four commercial tropical maize genotypes (H627, H625, H513 and DLC1) were screened in vitro for callus initiation and plant regeneration from immature embryos. Callus was initiated on N6 medium supplemented with varying ... -
Influence of cultivation, settlements and water sources on wildlife distribution and habitat selection in south-east Kajiado, Kenya
(Environmental Conservation, 2008)In Kenya, lands surrounding wildlife protected areas (PAs), referred to as dispersal areas, have undergone widespread land use changes, but these have been little studied. This study investigated impacts of different land ... -
Development of a Non-Mist Vegetative Propagation Protocol for Eucalyptus Hybrid Clones
(Journal of East African Natural Resources Management, 2009)Eucalyptus trees have proved to be a popular species for farm forestry,however their vegetative propagation has not been optimised mainly due to the high cost of infrastructure used to propagate them in mist ... -
