Additive main effects and multiplicative interaction analysis of genotype x environmental interaction among sweetpotato genotypes
Mwololo, J.K.; Muturi, Phyllis W.; Mburu, M.K.; Njeru, R.W.; Kiarie, N.; Munyua, J.K.; Ateka, E.M.; Muinga, R.W.; Kapinga, R.E.; Lemaga, B. (2009-04-08)Sweetpotato is an important food, feed and cash crop in Eastern Africa. Highly stable and adaptable genotypes are important in sweetpotato productivity and evaluation across sites would form a basis for breeding varieties ... -
Agro-morphological characterization of horned melon (Cucumis metuliferus) accessions from selected agro-ecological zones in Kenya
Owino, Marline H.; Gichimu, Bernard M.; Muturi, Phyllis W. (Australian Journal of crop science, 2020-09)Morphological characterization of genotypes is fundamental in providing information on their genetic status to guide on their conservation and improvement. The objective of this study was to determine agro-morphological ... -
Characterization of the Volatile Components of Essential Oils of Selected Plants in Kenya
Mugao, Lydia G.; Gichimu, Bernard M.; Muturi, Phyllis W.; Mukono, Simon T. (Hindawi, 2020-12)Essential oils are secondary metabolites that plants produce for protection from pests and predators, attraction of pollinators, and seed dispersal. )e oils are made up of a mixture of compounds that give a characteristic ... -
Identification of new sorghum genotypes resistant to the African and spotted Stem borers
Muturi, Phyllis W.; Mgonja, M.; Rubaihayo, P. (2014)Lepidopteran stemborers, mainly the African stemborer Busseola fusca Fuller and spotted stemborer Chilopartellus Swinhoe, are among the economically important pests of sorghum in Kenya. Identification of sources of resistance ... -
In Vitro Control ofPhytophthora infestans and Alternaria solani Using Crude Extracts and Essential Oils from Selected Plants
Mugao, Lydia G.; Muturi, Phyllis W.; Gichimu, Bernard M.; Njoroge, Ezekiel K. (Hindawi, 2020-07)Tomato production is constrained by fungal diseases especially the early and late blight caused by Alternaria solani and Phytophthora infestans, respectively. Control of the two diseases is usually by use of synthetic ... -
Influence of drought on interactions between Rhopalosiphum padi and ground dwelling predators – A mesocosm study
Njue, Martin; Muturi, Phyllis W.; Nyaga, Justine M.; Jonsson, Mattias (Wiley, 2021-05)Climate change will lead to extreme droughts, but it is difficult to predict how this will affect crop pests. In particular, it is unclear how interactions between natural en- emies and pests will be influenced. In the ... -
New sources of resistance to spotted stem borer, Chilo partellus in sorghum
Muturi, Phyllis W.; Rubaihayo, P.; Mgonja, M.; Kyamanywa, S.; Kibuka, J.; Sharma, H.C. (2012)The lepidopteran Chilo partellus Crambid, an introduced pest in East and southern Africa from Asia, is the most economically important stem borer species infesting cereals in Africa. Chilo partellus causes more than 40% ... -
Novel source of sorghum tolerance to the African stem borer, Busseola fusca
Muturi, Phyllis W.; Rubaihayo, P.; Mgonja, M.; Kyamanywa, S.; Sharma, H.C.; Hash, C.T. (Academic Journals, 2012-08)Sorghum (Sorghum bicolor) is an important cereal food crop in semi-arid tropics, but its productivity is curtailed mainly by insect pests and diseases. The African stem borer, Busseola fusca Fuller (Lepidopteran: Noctuidae), ... -
An overview of advances in bioinformatics and its application in functional genomics
Mwololo, J.K.; Munyua, J.K.; Muturi, Phyllis W.; Munyiri, S.W. (2010-04-28)Bioinformatics is the scientific discipline that is concerned with the efficient management and useful interpretation of large scale biological information. Functional genomics aims at mapping DNA sequences and the ... -
Performance of sweet potato varieties across environments in Kenya
Mwololo, J.K.; Mburu, M.K.; Muturi, Phyllis W. (2012-09)Sweetpotato is an important food, feed and cash crop in Eastern Africa but its adoption as a dual purpose crop has not been exploited. Varieties giving high tuber and vine yields would be ideal for small scale farmers who ... -
A perspective on proteomics: current applications, challenges and potential uses
Muturi, Phyllis W.; Mwololo, J.K.; Munyiri, S.W.; Rubaihayo, P.; Munyua., J.K.; Mgonja, M.; Manyasa, E.; Kiarie, N. (Academic Journals, 2010-08)Biological sciences are experiencing an ongoing information revolution. Proteome-wide functional classification using bioinformatics approaches is becoming an important method for revealing unknown protein functions. ... -
Utilization of proteins and nucleic acids in the study of gene function: a comparative review
Mwololo, J.K.; Karaya, H.G.; Munyua, J.K.; Muturi, Phyllis W.; Munyiri, S.W. (2010)Proteomics is one of the fastest growing areas in areas of research, largely because the global-scale analysis of proteins is expected to yield more direct understanding of function and regulation than analysis of genes. ...
