What is it about?
The high cyanogenic glucosides content in some cassava varieties prevents herbivory but can be toxic for human consumption. Identification of an intracellular transporter gene and its allelic variation allow to point out cultivars with up to 30 percent decrease in cassava root cyanogenic glucosides content.

Why is it important?
The high dietary cyanogen consumption from insufficiently processed roots of bitter cassava combined with a protein-deficient diet leads to a neglected disease known as konzo. This study seeks to understand the genetic mechanism of hydrogen cyanide or HCN (representing total cyanogenic glucosides) content regulation in cassava root and the identification of closely linked SNP markers to enhance efficiency and cost effectiveness through marker assisted selection in cassava breeding.
