Recent advances in our understanding of abscisic acid (ABA) signaling have identified a core pathway consisting of receptors (PYR/PYL/RCAR), protein phosphatases (PP2C), protein kinases (SnRK2), and several downstream factors that will lead to the next stage of ABA research. Systems biology will be an important concept for further understanding ABA responses in plants. In this review, two practical approaches of systems biology to ABA signaling are presented: the one is 'transcriptome analysis', which covers coding genes as well as unannotated transcripts, and the other is 'phosphoproteomics'. The latter technology will offer an unprecedented overview of the regulatory networks involved in ABA signaling because protein phosphorylation/dephosphorylation is a major center of such regulation. Systematic studies will contribute to our understanding of the network structure and dynamics of ABA signaling; moreover, systems biology will facilitate ABA signaling studies as well as future biotechnological applications in crops or trees.
