Holistic overview of regulatory networks governing seed dormancy and germination in plants

Seed dormancy and germination are crucial processes affecting the propagation and survival of plant populations. These phenomena are precisely regulated through a complex interplay between internal signals, such as plant hormones and environmental cues including light, temperature, moisture, and nutrient availability. Dormancy release and germination initiation are distinct, yet closely associated, processes involving complex transcriptional, translational, and epigenetic changes mediated by intricate regulatory mechanisms. This review comprehensively summarizes the complex regulatory networks governing seed dormancy and germination across different plant species. By integrating physiological, genetic, and molecular biology perspectives, the latest advances in the research on mechanisms regulating seed dormancy and germination are discussed, providing valuable insights for improving seed quality through biotechnology-based breeding strategies and establishing a solid foundation for future research in this field.
