"The potato (Solanum tuberosum L.) is considered the fourth most significant food security crop globally. As with other crops, growth of the potato plant is affected by many environmental stresses such as drought, salinity, and intense temperature all of which reduce its productivity. In the case of developing tolerance to abiotic stresses through transgenic approaches, genes such as isopentenyltransferase (IPT), XERICO, and mannose 6-phosphate reductase (M6PR) have been cloned for the purpose of addressing drought tolerance in potato and other crops. In this study, we transformed the three different genes XERICO, M6PR, and IPT into the tetraploid S. tuberosum a cultivar (CV) Désirée, a red-skinned variety with high transformation efficiency and susceptibility to drought stress, to evaluate the response of transgenic lines to drought conditions in both the laboratory and greenhouse." -- Abstract.
