Water is the most limiting factor for plant growth and crop productivity. Drought stress adversely affects crop yield throughout the world. Up to 50% of crop yield in Pakistan is severely affected by the shortage of water. Cotton is an important cash crop for Pakistan known as "white gold." It accounts for 8.2% of the value added in agriculture and about 3.2% of GDP. Besides, being the world's fourth-largest cotton producer, our yield per acre ranks 13th in the world. If we look at the Pakistan scenario, water deficiency is one of the major yield-limiting factors. Limitations related to conventional breeding and the advancements in plant genomics and biotechnology applications have opened new horizons to plant improvements. Therefore, in the current study, we carry out a comparative analysis to evaluate the morphological, physiological biochemical and molecular parameters in transgenic plants containing GaUSP-1, GaUSP-2 and GaZinc Finger genes under different drought stress conditions. Data showed that transgenic plants showed more tolerance as compared to non-transgenic plants. Transgenic and non-transgenic assist us in our better understanding of the drought-responsive mechanism and its effect on different plant growth traits, so, in this way, we would be able to explore drought tolerance mechanism and this will open the doors for the identification of drought-related genes.
