Validation of GmbZIP15 binding site and function analysis of three binding genes
(A) Diagram of the G-box distribution of GmABF1, GmJAZ8, and GmERS1 promoter fragments and wild-type G-box element (ACGT) was mutated to mG-box element (GATC).
(B)Yeast one-hybrid assay using vectors contains GmbZIP15 binding site or fragments with introduced mutations. Yeast cells carting or lacking pGAD-GmbZIP15 were grown on SD/-Ura or SD/-Ura, SD/-Ura/-Leu containing 300 ng/mL AbA.
(C) EMSA of the binding sites of GmbZIP15 protein to the promoter of GmABF1, GmJAZ8, and GmERS1. 5x or 10x competitor probe DNA (unlabeled) were added as control in the assay.
