Summary
Fruits are economically and nutritionally vital, with their development and quality (e.g., flavor, texture, antioxidants) shaped by complex molecular and physiological networks. Amid global demand for high-quality produce, unraveling these mechanisms is critical for crop improvement and sustainable horticulture. This Special Issue aims to showcase cutting-edge research on the molecular pathways, physiological regulators, and environmental interactions governing fruit development (flowering, fruit set, ripening) and quality formation. We welcome studies on gene regulation, hormone signaling, metabolomic profiling, and stress responses related to fruit quality. Suggested themes include: molecular basis of fruit ripening and softening, genetic regulation of bioactive compound biosynthesis, physiological responses to abiotic/biotic stresses, and multi-omics integration in quality trait dissection.
