Abstract

In apple (Malus domestica), the abscisic acid (ABA)-responsive factor ABA INSENSITIVE5 directly activates MORE AXILLARY GROWTH2 (MdMAX2), an important strigolactone signaling component; an abscisic acid-restricted E3 ubiquitin ligase modulates MdMAX2 turnover, thus linking strigolactone and abscisic acid signaling.

Keywords: MAX2; MIEL1; abscisic acid; strigolactone; transcription regulation; ubiquitination regulation.
