North Carolina State University will receive $12.4 million over the next four years from the Bill & Melinda Gates Foundation to improve a crop that is an important food staple in sub-Saharan Africa – the sweet potato. The grant will fund work to develop modern genomic, genetic and bioinformatics tools to improve the crop’s ability to resist diseases and insects and tolerate drought and heat. Sweet potatoes are an important food security and cash crop with potential to alleviate hunger, vitamin A deficiency and poverty in sub-Saharan Africa. More than 13.5 million metric tons are produced in sub-Saharan Africa annually; they are predominantly grown in small plot holdings by poor women farmers. Read more from University News Services.
