Overexpression of Gene Improves Tolerance of Drought Susceptible Groundnut ( L.) Cultivar K-6 by Increased Leaf Epicuticular Wax Accumulation.

Drought is one of the major environmental constraints affecting the crop productivity worldwide. One of the agricultural challenges today is to develop plants with minimized water utilization and reduced water loss in adverse environmental conditions. Epicuticular waxes play a major role in minimizing water loss.

A Novel WRKY Transcription Factor, ( Lam. Verdc.) Enhances Drought Stress Tolerance in Transgenic Groundnut ( L.) Plants.

Drought stress has adverse effects on growth, water relations, photosynthesis and yield of groundnut. WRKY transcription factors (TFs) are the plant-specific TFs which regulate several down-stream stress-responsive genes and play an essential role in plant biotic and abiotic stress responses. We found that gene is highly up-regulated under drought stress conditions and therefore isolated a new gene from a drought-adapted horsegram ( Lam.
