Genetic diversity and use of African indigenous vegetables especially slender leaf
(Taylor and Francis, 2020-10)African indigenous (AIVs), and traditional, vegetables play a role in food security. This review examines distribution, use, diversity, and techniques used to study AIVs with special interest on Crotalaria ... -
Genetic Diversity of Cassava Mutants, Hybrids and Landraces Using Simple Sequence Repeat Markers
(SCIENCEDOMAIN international, 2014-10-11)Aims: Cassava (Manihot esculenta Crantz) is a crop with largely unexplored and unexplained potentially valuable genetic variability. The knowledge and understanding of the extent of genetic variation of cassava germplasm ... -
Genetic Improvement of African Maize towards Drought Tolerance: A Review
(IISTE, 2016)Africa supports a population of over 1 billion people with over half of them depending on maize for food and feed either directly or indirectly. Maize in Africa is affected by many stresses, both biotic and abiotic ... -
Genetic Transformation of Sweet Potato for Improved Tolerance to Stress: A Review
(2016-10)The sweet potato (Ipomoea batatas Lam) is a major staple food in many parts of the world. Sweet potato leaves and tubers are consumed as food and livestock feed. Biotic and abiotic stresses affect yield leading to a ... -
Genotypic diversity of Dictyosphaerium–morphospecies (Chlorellaceae, Trebouxiophyceae) in African inland waters, including the description of four new genera
(2012)Trebouxiophytes of the Dictyosphaerium–morphotype from inland waters of Africa were studied using a polyphasic approach of SSU and ITS rDNA phylogeny, secondary structure of the ITS and observations made with a light ... -
Geographic Distribution of Rabies Virus and Genomic Sequence Alignment of Wild and Vaccine Strains, Kenya
(UoEm, 2024-08-08)Rabies, a viral disease that causes lethal encephalitis, kills ≈59,000 persons worldwide annually, despite availability of effective countermeasures. Rabies is endemic in Kenya and is mainly transmitted to humans through ... -
Geomorphic and Climatic Drivers Are Key Determinants of Structural Variability of Mangrove Forests along the Kenyan Coast
(MDPI, 2022-06)Mangrove forests occur across a diversity of coastal landforms that influence their structural development and productivity. Preliminary studies in Kenya indicate that mangroves growing in the region north and south of ... -
The Glossina proteolytic lectin (Gpl) gene is expressed only in members of Glossina species
(2008)Differentiation of bloodstream-form trypanosomes into procyclics in tsetse flies (Diptera: Glossinidae) is a crucial step in the establishment of midgut infections. A number of factors have been implicated in the ... -
The Glossina proteolytic lectin (Gpl) gene is expressed only in members of Glossina species
(2007-12)Differentiation of bloodstream-form trypanosomes into procyclics in tsetse flies (Diptera: Glossinidae) is a crucial step in the establishment of midgut infections. A number of factors have been implicated in the transformation ... -
Growth and nutrient uptake among three wetland plant species occurring in Lake Victoria basin in Kenya.
(2010)Nutrient enrichment is one of the most serious threats to wetland ecosystems. Information is lacking, particularly concerning the response of wetland plants species in Kenya in regard to nutrient enrichment of wetlands. ... -
Haloleptolyngbya alcalis gen. et sp. nov., a new filamentous cyanobacterium from the soda lake Nakuru, Kenya
(Springer, 2012)The food web of the saline-alkaline Lake Nakuru is dominated by the cyanobacterium Arthrospira fusiformis as the primary producer and a huge population of Lesser Flamingos as direct consumers. However, the dense blooms ... -
Heavy Metals and Pesticides in Marine Sediment, Seawater, and Seaplants Along the Kenya-Mombasa Coastline
(Taylor & Francis, 2003)Marine sediment, seawater and several species of seaplants along the Kenya- Mombasa coastal region were analyzed to determine the levels of heavy metals by AAS and EDXRF and organochlorine pesticides (OCPs) by GLC-ECD. In ... -
