Agricultural Sciences: Yesterday, Today, and Tomorrow

Charles Valentine Memorial Lecture, 20 Nov. 2024 (C.S. Prakash, Lisa Ainsworth, Anastasia Bodnar, and Kate Tully)

I want to highlight a lecture recently given by one of the most influential scientists in the international debate on GMOs and gene editing in agriculture. Born in India, C. S. Prakash lives and works in the U.S. and has been elected a fellow of the American Association for the Advancement of Science (AAAS). His lecture, delivered at the AAAS Center for Scientific Evidence in Public Issues, traces the progress made over the past sixty years in the field of global food security—i.e., meeting the growing demand for food from the world’s population.

Genome editing for smallholder farmers

A few months ago Nature Genetics published an article on “Genome-edited crops for improved food security of smallholder farmers”. It lists the applications being studied at the CGIAR consortium of agricultural research centers: “climate resilience in rice; disease resistance in banana, maize, potato, rice, wheat and yam; and nutrition improvement and consumer and environmental safety traits in cassava”. Additional traits include “brown streak virus resistance and haploid induction in cassava; nutritional quality and digestibility in bean; Striga resistance in sorghum; low phytate and high provitamin A in maize; reduced acrylamide, phytate and polyphenol oxidase in wheat; reduced aflatoxin in groundnut; delayed flour rancidity in pearl millet; reduced glycaemic index and apomixis in rice; and heat tolerance and apomixis in potato”. We emailed the CIMMYT’s scientist who leads the Genetic Resources work and is the first author of the NatGen article for an updated comment about the CGIAR’s vision of genome editing in agriculture. Kevin V. Pixley answers our questions below
