Figure 4. Expression of putative ethylene and ABA biosynthesis and signaling genes in soybean.

Figure 4

A. A schematic diagram depicting ethylene biosynthesis and signaling [69] is given on the left while expression data of differentially expressed transcripts for respective annotated homologs are given on the right panel. Ethylene is perceived by repressing the action of receptor complexes including ETR/ERS/EIN4 receptors, RTE1, and Raf-like protein kinase CTR1, which negatively regulates downstream signaling component. When EIN2 is activated in the presence of ethylene, it stabilizes EIN3. EIN5/XRN4 regulates EBF1 (EIN3 BINDING F-BOX1) that degrades EIN3 in the absence of ethylene. B. Expression data of differentially expressed transcripts related to ABA (top) or trehalose (bottom) metabolism are shown. NCED, Nine-cis-epoxycarotenoid dioxygenase; AAO3, abscisic aldehyde oxidase3; UGT84B1, ABA glucosyltransferase; CYP707A, ABA hydroxylase; GPCR, G-protein coupled receptor for ABA; ABA4, ABA-deficient 4; ABF1, ABA-responsive element-binding factor1. Expression level is as in Figure 3.
