This study investigates the interaction between AP2C1 and various AtMKKs using a yeast two-hybrid system. We transformed the L-40 yeast strain with pGAD424-AP2C1 and pBTM-MKK constructs, analyzing lacZ reporter gene activation through β-galactosidase assays. Notably, MKK3 displayed autoactivation in this assay. The results highlight the functional interplay between AP2C1 and AtMKKs, contributing to our understanding of their roles in signaling pathways.

The activation of lacZ reporter gene was analyzed by β-galactosidase assay. MKK3 is autoactive in yeast two hybrid assay. The pBTM-MKK3 bar shows β-galactosidase activation by co-expressing pBTM-MKK3 and empty pGAD vector Suppl. Figure 1
