      abstract     = {Potato tubers comprise $83\%$ water at harvest, but
                      surprisingly few studies address tuber water relations in
                      drying soil. This study aims to understand whether soil
                      drying alters tuber water fluxes and their effect on tuber
                      volume growth.MethodsTuber water content and volume growth
                      were investigated every 4 h using magnetic resonance imaging
                      (MRI) during soil drying and re-watering, with leaf gas
                      exchange, leaf water potential and foliar abscisic acid
                      (ABA) concentration measured concurrently.Tubers of
                      well-watered plants showed a diurnal growth pattern with
                      their volume and average water content (TWC) increasing
                      overnight. Withholding irrigation caused typical shoot
                      drought stress responses (e.g. stomatal closure), dampened
                      fluctuations in total TWC and paused nocturnal volume
                      growth. Irrespective of soil moisture, tubers lost water
                      (likely to the shoot) during the daytime when the plant
                      transpires, while tuber water loss to the soil was minimal.
                      Re-watering restored tuber volume growth and average TWC due
                      to root water uptake and transport to the tuber.Potato
                      tubers can supply water to the shoot. Nocturnal water influx
                      needs to exceed daytime water efflux for net tuber volume
                      growth, which should be considered in irrigation
                      management.},
