Recent studies have advanced understanding of gene regulation and systemic signaling in plants, including a mobile transcription factor coordinating nitrogen deficiency responses across plant organs and discoveries of transcription factor recruitment mechanisms influencing flowering plants’ development. Additional research presents new biosensors for real-time monitoring of sucrose uptake and elucidates microRNA-driven dosage compensation in birds. These insights offer transformative potential for agricultural biotechnology, enhancing crop resilience and productivity through molecular breeding and targeted nutrient management.
