Understanding the multifaceted role of ABA signaling in orchestrating plant developmental transition

Abstract Abscisic acid (ABA), a pivotal plant hormone once primarily associated with stress response, is now increasingly acknowledged for its indispensable role in plant development. This comprehensive review delves into the multifaceted functions of ABA in regulating various aspects of plant growth and development. From inhibiting germination to orchestrating seedling establishment, flowering time, and dormancy induction, ABA emerges as a central player in shaping plant developmental transitions. Unraveling the intricate regulatory mechanisms governing the ABA signaling pathway provides valuable insights into how plants adapt to environmental challenges while effectively managing their growth and reproductive strategies. This expanding knowledge not only highlights the significance of ABA in plant biology but also has profound implications for enhancing agricultural practices.
