Fine Mapping and Transcriptome Analysis of Virescent Leaf Gene v-2 in Cucumber (Cucumis sativus L.)
(Frontiers in Plant Science, 2020)Leaf color mutants are the ideal materials to explore the pathways of chlorophyll metabolism, chloroplast development and photosynthesis system. In this study, a new virescent leaf mutant 104Y was identified by spontaneous ... -
First detailed morphological characterisation of qualitative traits of extensive naturalized pumpkin germplasm in Kenya
(ISDS LLC, Japan, 2015)Pumpkin (Cucurbita moschata (Lam.) Poir) is emerging as an important fruit-vegetable in Kenya. However, its economic and nutritional benefits remain under-exploited, while its conservation is threatened owing to limited ... -
Fluorescent SSR Markers and Capillary Electrophoresis Reveal Significant Genetic Diversity in Naturalized Pumpkin Accessions in Kenya
(2017)This study was undertaken as a preliminary step in determining genetic diversity of naturalized pumpkins in Kenya. It entailed allelic patterns, frequency, inbreeding coefficient, molecular variance, cluster and ... -
Food and income provision influence production of pumpkins in Kakamega and Nyeri in Kenya
(2018)Pumpkin is an emerging important fruit-vegetable, although its potential remains unexploited in Kenya. This study aimed at enhancing conservation, preservation and production of naturalized pumpkins through characterisation ... -
Food safety knowledge and practices of street food vendors in selected locations within Kiambu County, Kenya
(African Journal of Food Science, 2020)The safety of street foods remains a public health concern especially in developing countries like Kenya where foodborne illnesses associated with these foods have often been reported. This study determined the food ... -
Genetic Diversity Analysis in Tropical Maize Germplasm for Stem Borer and Storage Pest Resistance using Molecular Markers and Phenotypic traits
(2015)One hundred maize inbred lines and eighty four hybrids were characterized for resistance to maize stem borer and post-harvest insect pests. This was achieved using genetic distance and population structure based on simple ... -
Genetic diversity of pumpkin accessions in Kenya revealed using morphological characters, diversity index, CATPCA and factor analysis
(2018-02)Pumpkin is one of the most morphologically variable genera in the entire plant kingdom. In Kenya, its genetic diversity is undocumented and distribution is haphazard. An expedition was done in Kakamega and Nyeri regions ... -
Genetic variation of growth dynamics in maize (Zea mays L.) revealed through automated non-invasive phenotyping.
(John Wiley & Sons Ltd, 2017)Hitherto, most quantitative trait loci of maize growth and biomass yield have been identified for a single time point, usually the final harvest stage. Through this approach cumulative effects are detected, without considering ... -
Genome-Wide Identification of GASA Gene Family in Ten Cucurbitaceae Species and Expression Analysis in Cucumber
(MDPI, 2022)Gibberellic acid-stimulated in Arabidopsis (GASA), a unique small molecular protein of plants, plays an essential role in plant growth and development. The GASA family genes have been identified and studied in many plants. ... -
Genome-Wide Identification of the B-Box Gene Family and Expression Analysis Suggests Their Potential Role in Photoperiod-Mediated β-Carotene Accumulation in the Endocarp of Cucumber (Cucumis sativus L.) Fruit
(MDPI, 2022)Carotenoids are indispensable to plants and essential for human nutrition and health. Carotenoid contents are strongly influenced by light through light-responsive genes such as B-Box (BBX) genes. BBX proteins, a class ... -
Genome-Wide Identification, Phylogenetic and Expression Pattern Analysis of GATA Family Genes in Cucumber (Cucumis sativus L.)
(MDPI, 2021)GATA transcription factors are a class of transcriptional regulatory proteins that contain a characteristic type-IV zinc finger DNA-binding domain, which play important roles in plant growth and development. The GATA ... -
Growth of ranunculus cutflower under tropical high altitude conditions.
(Horticultural Association of Kenya, 2009)Cutflower production and marketing is partly challenged by lack of new, exciting and improved varieties to satisfy customer needs of a different flower. Ranunculus (Ranunculus asiaticus L.) is a bulbous plant that originated ... -
Growth of ranunculus cutflower under tropical high altitude conditions. 2: Effects of GA3 and shade on light intensity and temperature modification
(Horticultural Association of Kenya, 2009)Customer needs of a different flower are increasing over time worldwide. Many bulbous plants including ranunculus fit the category of a different flower because they are not known. Ranunculus(Ranunculus ... -
Household responses to COVID-19 shocks: A food security implication in Kenya
(Prime Scholars Library, 2022)The primary objective of this study was to determine household coping mechanisms under COVID-19 pandemics and its implication on food security in the country. Poisson regression model was used to describe the relationship ... -
Impact of land use/land cover changes on ecosystem service values in the cherangany hills water tower, Kenya
(Elsevier, 2022)Land Use/Land Cover (LULC) changes alter the ecosystem structure and function, resulting in variations of the Ecosystem Service Values (ESVs). This study investigated the impacts of LULC changes on ESVs over 37 years in ... -
