Progress in transformation and regeneration of tropical inbred maize lines in Kenya
(Maize Genetics Cooperative Newsletter, 2008)Tropical inbred maize lines have a reputation of being difficult to transform, mainly as a result of their inherent limitations associated with resistance to Agrobacterium infection and their recalcitrance to in vitro ... -
Use of a non-mist propagation system to vegetatively propagate 12 E. grandis X E. Camadulensis hybrid clones
(Kenyatta University, 2009) -
Evolution and diagnostic utility of major surface proteases from trypanosoma vivax, t. Brucei brucei and t. Congolense
(Kenyatta University, 2009) -
Preferred Banana Varieties and their Seed Systems in Eastern and Central provinces of Kenya
(Ruforum, 2010)Banana is an important crop for food security in Kenya. Its production has been hindered by scarcity of seedlings and pests, among other factors. A recent survey in eastern and central Kenya showed that desert varieties ... -
Regeneration and transformation potential of elite Kenyan highland maize inbred lines
(2010)Agrobacterium-mediated transformation of tropical maize has been manipulated in only a limited number of genotypes, because a majority of maize germplasm isrecalcitrant toin vitroresponse. Establishment of a highly efficiency ... -
Prospecting for bacillus thuringiensis for the control of prostephanus truncatus (horn) and sitophilus zeamais motschulsky
(2010)Three hundred twenty nine samples from different parts of Kenya which had not previously been treated with bio-pesticide were collected for Bacillus thuringiensis isolation. The δ-endotoxin crystals were isolated from ... -
Optimisation of parameters for agrobacterium-mediated transformation of sweet potato
(2010)An Agrobacterium-mediated transformation and somatic regeneration protocol was adapted for a Kenyan sweet potato variety, KSP36. A model cultivar, CTP560 was used as a control. For selection of transformed explants paramomycin ... -
Interaction of cassava mosaic disease and cassava brown streak disease in nicotiana benthamiana
(2010)The interaction of Cassava mosaic geminivirus (CMG)and Cassava brown streak virus (CBSV) were tested in Nicotiana benthamiana. The inoculated virus and/or virus species were CMGs species (ACMV and EACMV-UgV), CBSV and dual ... -
Effect of 2, 4-d levels on callus induction of leaf and stem explants of 5 local farmer-preferred sweet potato varieties in Kenya
(2010)Five local and popular sweet potato (Ipomoea batatas(Lam.) varieties were selected from the major sweet potato growing areas, based on farmer-preferences and desirable characteristics. Both leaf and stem explants were ... -
Macropropagation Technique for Production of Healthy Banana Seedlings.
(African Crop Science Society, 2011)Banana (Musa spp) is one of the most important crops providing food security, nutrition and income for many smallholder farmers in sub-Saharan Africa. However, production is hindered by scarcity of high quality seedlings, ... -
Banana Distribution and their Seed Systems in Central and Eastern Kenya.
(African Crop Science Society, 2011)Bananas (Musa spp.) serve as food, income resource and animal feed in addition to other environmental benefits. In Kenya, the crop is mainly grown and managed by smallholder farmers. Over the last two decades, banana ... -
Prospects of biofuel production from microalgae in Kenya
(2012)With the depletion of oil resources as well as the negative environmental impact associated with the use of fossil fuels, there is a renewed interest in seeking alternative energy sources. The present study was conducted ... -
Efficacy of transgenic kernels harbouring the cry3a gene from bacillus thuringiensis in the control of the larger grain borer and maize weevil
(2012)Insect bioassays were conducted to evaluate the efficacy of maize seed kernels expressing protein of aδ-endotoxin gene of Bacillus thuringiensis tenebrionis Cry3A against economically important coleopteran pests in stored ... -
Genotype independent somatic embryogenesis and plant regeneration from immature zygotic embryos of tropical maize inbred lines
(2012)Maize is one of the most important cereal crops in Sub-Saharan Africa and an important source of energy for humans. However, the difference in the dedifferentiation frequency of immature embryos among various genotypes ... -
In vitro selection and characterization of salinity tolerant somaclones of tropical maize (Zea mays L.)
(2014-05-12)Tolerance to salinity was obtained in an open pollinated variety (KAT) widely grown in the East African region and a dryland hybrid (PH01) by applying in vitro selection and regeneration procedures. Immature zygotic embryos ... -
In Vivo Toxicological and Histopathological Effects of Aflatoxin B1 Exposure and Related Risk
(ICHWB (International Conference on Health & Well-Being), 2016)Aflatoxin B1 are toxic metabolites of Aspergilus flavas and Aspergilus parasiticus which usually contaminant foods such peanuts, corn, and other grains as well as animal feeds resulting into intoxication. Studies have ...
