|a Potato (Solanum tuberosum L.) is nowadays an important component of diversified cropping systems due to its adaptability, yielding capacity, and nutrition contribution. Breeding programs aiming at raising potato's nutritional value have mainly focused on the accumulation in potato tubers of health-promoting phytochemicals such as anthocyanins. In different plant species, increased amounts of anthocyanins in vegetative tissues have been associated with enhanced tolerance to abiotic and biotic stresses that challenge agrifood systems in the current context of global climate change. In the present study, we aimed at gaining insight into the effect of anthocyanin accumulation on the potato plants response to drought stress using three different potato genotypes with differential canopy and tuber pigmentation: the purple fleshed commercial variety Bleuet; the red fleshed breeding clone DAR170; and the non-pigmented commercial variety Monalisa. The varieties Bleuet and DAR170 exhibiting higher anthocyanin content in vegetative tissues than the Monalisa variety showed a remarkable inhibition of stem growth development under drought stress treatment suggestive of an anthocyanin-mediated physiological shift from growth to resilience as a mechanism of stress tolerance. The results of the expression analysis of stu-miR156a and its target StSPL9 gene in the potato plants with different anthocyanin content, as well as their change in response to drought stress support the participation of the conserved miR156-SPL9 regulatory module in coordinating potato plants development and plant responses to drought stress, involving precise fine-tuning of anthocyanin biosynthesis
