Item Comparative Compositional Analysis of Cassava Brown Streak Disease-Resistant Cassava 4046 and Its Non-Transgenic Parental Cultivar(Taylor & Francis Online, 2021-11-04) Wagaba, H.; Kuria, P.; Wangari, P.; Obiero, A.H.; Beyene, G.; Alicai, T.; Bua, A.; Esuma, W.; Nuwamanya, E.; Gichuki, S.; Miano, D.; Raymond, P.; Kiggundu, A.; Taylor, N.; Zawedde, B.M.; Taracha, C.; MacKenzie, D.J.; National Crops Resources Research Institute ; Kenya Agricultural and Livestock Research Organization ; Institute for International Crop Improvement ; Donald Danforth Plant Science Center ; University of Nairobi AG SCI Consulting.Compositional analysis is an important component of an integrated comparative approach to assessing the food and feed safety of new crops developed using biotechnology. As part of the safety assessment of cassava brown streak disease resistant 4046 cassava, a comprehensive assessment of proximates, minerals, amino acids, fatty acids, vitamins, anti-nutrients, and secondary metabolites was performed on leaf and storage root samples of 4046 cassava and its non-transgenic parental control, TME 204, collected from confined field trials in Kenya and Uganda over two successive cropping cycles. Among the 100 compositional components that were assessed in samples of 4046 and control TME 204 cassava roots (47 components) and leaves (53 components), there were no nutritionally relevant differences noted. Although there were statistically significant differences between the transgenic and control samples for some parameters, in most cases the magnitudes of these differences were small (20%), and in every case where comparative literature data were available, the mean values for 4046 and control cassava samples were within the range of normal variation reported for the compositional component in question. Overall, no consistent patterns emerged to suggest that biologically meaningful adverse changes in the composition or nutritive value of the leaves or storage roots occurred as an unintended or unexpected consequence of the genetic modification resulting in 4046 cassava. The data presented here provide convincing evidence of the safety of 4046 cassava with respect to its biochemical composition for food and feed, and it could be considered as safe as its non-transgenic control.Item KALRO - Biotechnology Research Institute (BioRI) Annual Report 2022-2023(Biotechnology Research Institute, KALRO, 2023) Mireji, P.; Wanjala, K.; Makokha, S.; Lutta, H.; Auma, J.; Wamwiri, F.; Kuria, P.; Kariithi, H.; Okeyo, W.; Mwirigi, M.; KALRO - Biotechnology Research Institute (BioRI)To generate and promote animal, plant, and environmental biotechnology knowledge, infor-mation, and technologies that respond to clients’ demands and opportunities. This report underscores the significant progress made by our institute over the past year in ad-dressing critical challenges within the agricultural and livestock sectors in Kenya. Through a combination of innovative research initiatives and collaborative partnerships, we have success-fully developed cutting-edge biotechnological tools and solutions that contribute to enhancing productivity, resilience, and sustainability in agriculture. Our research endeavors have spanned a wide array of focus areas, including the development of disease-resistant crops, exploration of nutritional alternatives for livestock, implementation of technologies to boost crop production, the conduct of socioeconomic studies informing agricul-tural technology adoption, assurance of livestock product safety, advancement of disease vector control technologies, vaccine development, and the execution of impactful community outreach programs such as youth mentorship initiatives. These achievements underscore our unwavering commitment to leveraging the potential of biotechnology to benefit Kenyan farmers and the ag-ricultural sector as a whole.
