Markers and models for yield in potato

Plants fix atmospheric carbon in their leaves by using sunlight as energy source. Using only air, water and soil nutrients, plants are able to synthesise all the compounds required for growth and development. It is critical that these compounds are transported around the whole plant to provide the energy and building blocks for growth as well as long-term storage in seeds and tubers. In this project, we aim to investigate the system of molecular “taps” and “valves” in the plants’ plumbing system that facilitate the partitioning of resources to the potato tuber. We have identified a suite of key proteins that act both as long distance signals and regulators of sugar transporters. Here, we aim to use this knowledge for the rationalized breeding of potato with optimized efficiency of carbon transport and positive knock-on effects on yield stability and stress tolerance. To achieve this, we will identify all variants of transporters and regulators in potato and develop a mathematical model of potato sugar transport and its regulation.
