Newly-published study details comprehensive nutrient analysis of biotech cassava

An East African led team of scientists has published a comprehensive comparative assessment of the principal nutrients, minerals, amino acids, fatty acids, vitamins, and secondary metabolites in the leaves and storage roots from disease resistant (4046) cassava and its conventional parent (TME 204).   These data were collected from field trials in Kenya and Uganda…

Comparative compositional analysis of cassava brown streak disease resistant 4046 cassava and its non-transgenic parental cultivar ABSTRACT 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,…

Kenyan farmers to reap big from disease-resistant cassava

By Dr. Simon Gichuki After years of meticulous research, the Kenya Agricultural and Livestock Research Organization (KALRO) is seeking approval from the National Biosafety Authority to introduce a genetically modified cassava. The cassava line 4046 protects cassava from the devastating Cassava Brown Streak Disease (CBSD).  KALRO cassava breeders have already begun working to develop new…

Kenya: Embracing dialogue on GMO crops

A national dialogue on GM crops was held in Nairobi on April 24, signalling strong public interest in policies that enable the safe use of this technology for disease resistant cassava and other crops. Led by the Principal Secretary for Agricultural Research Prof. Hamadi Boga, and moderated by one of Kenya’s most respected media editors,…

Biofortification of field-grown cassava

Narayanan, Narayanan, N. et al. 2019. Biofortification of field-grown cassava by engineering expression of an iron transporter and ferritin. Nature Biotechnology 37:144-151. Abstract Less than 10% of the estimated average requirement (EAR) for iron and zinc is provided by consumption of storage roots of the staple crop cassava (Manihot esculenta Crantz) in West African human…

Biofortification of field-grown cassava by engineering expression of an iron transporter and ferritin Abstract: Less than 10% of the estimated average requirement (EAR) for iron and zinc is provided by consumption of storage roots of the staple crop cassava (Manihot esculenta Crantz) in West African human populations. We used genetic engineering to improve mineral micronutrient…

Cassava: Improve Diets in West Africa ?

A new study led by Danforth Center principal investigator Nigel Taylor and research scientist Narayanan Narayanan, demonstrated that it is possible to raise the iron and zinc content of cassava roots while maintaining yield and other plant characteristics that are important to farmers and consumers. With the help of Ihuoma Okwuonu of the National Root…
