The NF-YC–RGL2 module integrates GA and ABA signalling to regulate seed germination in Arabidopsis

Abstract

Crosstalk between gibberellic acid (GA) and abscisic acid (ABA) regulates seed germination. Here the authors show that NF-YC transcription factors can interact with the RGL2 DELLA protein to regulate expression of ABI5and therefore modulate ABA- and GA-responsive gene expression.
