Fig. 7From: AgMYB5, an MYB transcription factor from celery, enhanced β-carotene synthesis and promoted drought tolerance in transgenic ArabidopsisEffects of AgMYB5 expression on endogenous ABA biosynthesis pathway. A Endogenous ABA contents and (B) relative expression levels of ABA synthesis-related genes (AtABA1, AtNCED6, AtABA2, and AtAAO3) of WT and transgenic lines under normal and drought conditions.
