Abscisic Acid Synthesis and Response

Interactions among some of the hormonal and developmental signals and regulatory elements controlling seed maturation.In the upper portion (“Accumulation”), factors regulating gene expression during the progression through seed development are shown in boxes representing the relative timing and abundance of their expression. ABA accumulation is depicted in pale red triangles. PYL5 is the ABA receptor that is most highly expressed in mid-seed development, and therefore likely to mediate ABA signaling during this stage. To simplify the diagram, intermediates in this signaling pathway are not shown (see Fig.4 for details). In the lower portion (“Roles”), the events regulated by specific factors are shown. In both parts, arrows represent positive regulation and red bars indicate repression.
