Potato is the most important horticultural crop in Argentina. It is well adapted to many environmental conditions but certain abiotic stresses, such as salinity, cause significant reductions in growth and yield. Understanding how potato plants perceive and combat salt stress is fundamental to develop salt-tolerant plants that could expand actual crop frontiers. When exposed to NaCl, plants exhibit fast and transient increases in cytosolic Ca2+ within seconds; this early and prominent feature needs to be decoded by calcium sensors that transduce this signal into physiological responses. Calcium-dependent protein kinases (CDPKs) combine in a single protein both the sensing and the responding activity through EF-hand calcium-binding motifs and a protein kinase domain.In this work, we aimed to understand what role does StCDPK2 have in the salt stress response
