Plants have developed sophisticated mechanisms to detect and respond to stress conditions. The sesquiterpene phytohormone abscisic acid (ABA) has been linked to biotic and abiotic stress responses, seed dormancy and germination, seed maturation, floral transformation, seedling development, leaf senescence, and other processes, making it an important coordinator of plant-environment interactions. To date, the ABA biosynthetic pathways are clear, and a "PYR /PYL/RCAR-PP2C-SnRK2-AREB/ABF" core signaling module has been proposed and validated in plants.
Previous work has greatly expanded our knowledge of the role of ABA as a stress hormone. However, the exact function of ABA in plant development is still unknown. Elucidating the regulatory mechanisms of ABA on plant development will undoubtedly help answer basic scientific questions about plant development and provide means to improve plant productivity, especially under unfavorable growing conditions. The aim of this Research Topic is to provide an overview of the basic knowledge in the field of ABA-mediated plant growth control.
We welcome submissions of original research papers, reviews, and methods, including (but not limited to) research on the following sub-themes:
-Novel components and pathways involved in ABA signaling.
-ABA-induced OMIC responses in plant development.
-Crosstalk of ABA and other phytohormones in the regulation of plant development.
-Methods for the quantification of ABA in vitro and in vivo.
-ABA-related crop improvement.
