Emerging Plant Growth Regulators in Agriculture: Roles in Stress Tolerance

Plant Growth Regulators in Agriculture presents current PGR discoveries and advances for agricultural application, providing a comprehensive reference for those seeking to apply these tools for improved plant health and crop yield. Climate change exerts adverse effects on agricultural crop productivity. As demand for agricultural crops and improved nutritional requirement continue to escalate in response to increasing population, plant researchers have focused on identifying scientific approaches to minimize the negative impacts of climate change on agriculture crops. Among the various applied approaches, the application of plant growth regulators (PGRs) have gained significant attention for their ability to enhance stress tolerance mechanisms. Plant growth regulators (PGRs) are organic substances produced naturally in higher plants in minute amounts, or introduced as synthetics to enhance the source-sink relationship and stimulate the translocation of photo-assimilates by helping in effective flower formation, fruit and seed development and ultimately enhance the productivity of crops. These PGRs also affect gene expression and transcription levels, cellular division, and ultimately affect the growth. Moreover, they have the capacity to promote, inhibit, or modify physiological traits, development and/or stress responses. Research is also underway to identify potential regulators to reduce the burden of organic chemicals used. Plant Growth Regulators in Agriculture has been developed to provide foundational and emerging information to advance the discovery of novel, cost-competitive, specific, and effective PGRs for application in agriculture.
