Seed Dormancy and Germination as Models for Understanding Epigenetic Programming

Seed dormancy, an adaptation maximizing seedling survival and reproductive success, fine-tunes germination timing. Germination, the transition from dormancy to active growth, also requires intricate regulation for adaptation and survival. Epigenetic modifications act as dynamic molecular switches, influencing gene expression throughout these crucial stages. The dynamic epigenetic landscape allows plants to integrate environmental cues, facilitating precise spatiotemporal control of seed emergence. Consequently, seeds can optimize timing and location for successful establishment and reproduction. Unraveling the epigenetic mechanisms governing complex adaptive traits like seed dormancy and germination holds immense promise for manipulating physiological responses and adapting plants to challenging environmental conditions.
