About the research project
Potato (Solanum tuberosum) is one of the most important agricultural crops worldwide. This crop is somewhat unique in that it is not grown from seed but from tubers (modified stem storage organs). The age of tubers at planting has enormous impacts on the yield and quality of the resulting potato harvest. Tubers are known to have two different, yet related, ages: chronological age and physiological age. The chronological age is simply the time elapsed since the tuber was harvested; the physiological age (p-age) refers to the biochemical state of the potato and progresses at different rates, depending on the environmental conditions and the potato variety. Each potato variety has an optimal p-age at which it should be planted to maximise the uniformity, yield and quality of the harvest.
However, there currently exists no fast, accurate and robust method to measure potato p-age. In this project we will work with industry to investigate how the potato proteome changes over the course of aging with a view to identifying key protein biomarkers for p-age. Once these biomarkers are identified we will design bioassays that can be applied to tubers in an industrial context. Having a fast, accurate, robust easily-implementable assay for p-age will allow growers to a) properly understand the age of their tubers prior to planting, b) plant their tubers at the optimal time and c) adapt their management strategies to suit the age of their tubers to maximise crop yield, uniformity and quality.
This project has been co-designed with Simplot and Agronico. Where relevant, this project will be implemented on commercial farms, the Forthside Vegetable Research Facility and in glasshouse facilities offsite.
