dc.description.abstractThe growing need for stress-tolerant crops necessitates a comprehensive understanding of cellular, biochemical, and molecular responses to stress. Traditional breeding approaches, while effective, are time-consuming and limited to sexually reproducing species. In contrast, advancements in reproductive sciences, biotechnology, and recombinant DNA (rDNA) technologies enable precise genetic modifications, offering new opportunities to enhance crop resilience. Stress-induced genes and compatible solutes, such as proline, glycine betaine, and polyamines synthesized in plants, significantly improve tolerance to abiotic stresses. Late embryogenesis abundant (LEA) proteins, as key protective agents, safeguard cellular structures and maintain osmotic stability under stress conditions. Similarly, heat shock proteins (HSPs), conserved across species, play crucial roles in protein folding, stabilization, and protection, thereby enhancing photosynthetic efficiency and reducing oxidative damage. Transcription factors such as NAC, MYB, bZIP, and WRKY families are pivotal in regulating stress responses by altering physiological and biochemical pathways. Additionally, antioxidant defense systems, comprising enzymes like superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX), mitigate oxidative stress by scavenging reactive oxygen species (ROS). Recent breakthroughs in genome editing, particularly CRISPR/Cas9 technology, have revolutionized the ability to fine-tune stress-responsive genes, opening unprecedented possibilities for developing crops with enhanced resistance to unfavorable environmental conditions. These advancements in genetic engineering hold immense potential to sustainably increase crop resilience and ensure agricultural productivity in the face of climate change.en_US
