An Integrated Approach for Drought Tolerance Improvement in Rice
Drought is a major threat to agriculture globally and improving crop yield under drought conditions is a major challenge of plant breeding. Many QTLs have been identified for drought stress response, and researchers are striving hard to comprehend and dis

Foreword
“Rice is life,” feeding more than 50% of the global population today, but was known since 8000–10,000 years back. Rice, a crop originated from Indo-China regions, spread around the world along with the domestication, cultural revolution, improvement of the crop with scientific tools (conventional art of breeding, mutation breeding, genomic breeding, transgenesis, and genome editing), adaptation, and need-based policy decisions of different countries. Abiotic stress is a major environmental constraint to crop productivity, particularly rice. Breeding techniques, particularly genetic engineering, envisage at cross-talk between different stress-signaling pathways and are expected to find the road map of the metabolic pathways leading to stress tolerance. Osmotic adjustment (OA) is a powerful, effective component of abiotic stress (salinity and drought) tolerance in rice. Several stress-related genes, including transcription factor genes (DREB), and stress-induced promoters, including rd29, have n
