Relative expression levels of ATHB2 and ATHB5 in response to abscisic acid. Seeds were stratified in water or 5μM abscisic acid, and RNA was extracted after 12h. Expression levels of ATHB2 and ATHB5 were determined by qRT-PCR in imbibed seeds of ga1-3 rga, relative to Tubulin (TUB), and compared to ga1-3 rga rgl2-1. RQ = relative quantity of transcript.
