Introduction
Description:
ABA was originally used as a defoliant and noted for its role in leaf abcission. It was later found to regulate a number of processes associated with seed maturation and germination. Currently, it is the model compound for studying abiotic stress resistance in plants. It has also been used in cryopreservation pretreatments in bryophytes to improve cell survival rate after thawing.See Product Information Sheet for more details.

Application Notes
Abscission-accelerating plant hormone. ABA is involved in leaf abscission, stomal movement,
and helps mediate plant response to environmental stress. It has also been demonstrated to
regulate seed maturation and germination (Merck).
Has been shown to increase cell survival rate when used as a pretreatment in the liverwort Marchantia polymorpha prior to cryopreservation (Akter, 2014).
