Peptides, Modern Technology for Plant Defense Response for Sustainable Green Agriculture for Increasing worldwide populations

Peptides are short chains of amino acids that are the building blocks of chosen proteins. Peptides are a secure and efficient alternative to existing synthetic pesticides and insecticides. A constant and reasonable food supply is critical to the foundation of economic prosperity and growth in several countries. Innovations in fertilizers, pesticides, plant breeding, trait development, and improved farming methods are the main drivers of productivity and growth. India's per capita food prices are among the lowest in the world among healthcare, pharmaceuticals, animal nutrition, and plant nutrition. In current years, peptides have become widespread research targets in crop protection as antibacterial agents, immune inducers, plant growth regulators, insecticides, and herbicides due to their rich raw material sources, excellent activity, and supreme environmental compatibility. The present manuscript briefly introduces the advances in peptide research, provides an overview of peptide research in crop protection, and summarizes the utilization of peptides in crop protection and the prospects of peptides as green pesticides for agriculture and sustainable development for increasing populations.
