Student thesis: Doctoral ThesisPhD


Cassava is the sixth most important crop in the world, feeding over 500 million people worldwide. The storage root is a staple source of carbohydrates, and its ability to grow in nutrient-poor soil and drought tolerance make it an ideal food security crop. Cassava is also used as animal feed and in industry for starch and biofuel. The potential of
cassava is limited by several factors, with post-harvest physiological deterioration (PPD) of storage roots being a major constraint. PPD is a phenomenon triggered upon harvesting and mediated by reactive oxygen species and scopoletin accumulation that ultimately renders the storage roots unpalatable and unmarketable.
