Abstract
Cultivated potato crops are sensitive to drought stress, reducing yield and tuber quality when the soil water potential drops to -0.3 MPa. However, drought not only affects plant growth and physiological activity, but this stress also induces biochemical and molecular changes in the cellular gene expression profile. triggering genes that play a direct role in plant protection and gene regulation. The genes involved in regulation include C-repeat Binding Factors/Dehydration responsive element binding (CBF/DREB) transcription factors, which increase cold, drought and salt tolerance in different plant species. The aim of this research was to evaluate whether the ov...
