This thesis investigated the ability of sweet potato (Ipomoea batatas (L) LAM) to access and use P in low P soil conditions. Sweet potato tightly regulates internal P use allowing very low tissue P concentrations under a wide range of P supply, and has the ability to manage rhizosheath microbial communities for benefit under low- and high-P conditions. These findings will help to improve and stabilise storage root yield of sweet potato in both traditional subsistence agriculture and commercial high-input systems by selecting and breeding cultivars that enhance these traits.
