Emerging research in plant biology and agriculture integrates genomic and technological advances to improve crop yield, sustainability, and adaptation. Studies clarified distinctions between biologicals and biostimulants in crop inputs and regulatory frameworks, informing farmer and industry practices. New methods for real-time sucrose monitoring and nitrogen deficiency response regulation in plants have been developed. Innovations in renewable-energy-powered agriculture demonstrate significant emissions reductions and cost savings. Research also shows that tailored light spectra can enhance urban and vertical farming yields. Collectively, these efforts optimize plant growth and sustainability, aligning agriculture with environmental goals.
