Abscisic acid (W) is often referred to as a inhibitory rather than stimulatory hormone.
Complete blockage of the mevalonate pathway results in male gametophyte lethality. 2009
Cytoplasmic isoprenoids (e.g. sterols and brassinosteroids) and mitochondrial isoprenoids (e.g. side chains of ubiquinone) are synthesized via the MVA pathway, while the MEP pathway is used to synthesize plastidic isoprenoids (e.g. carotenoids and the side chains of chlorophylls and plastoquinones) and some isoprenoid-type phytohormones (e.g. gibberellins, abscisic acid, and cytokinins).
Requirements: Mb, NAD+ (not NADP)
It does so by inhibiting protein synthesis and dehydration processes.
Target genes of ABA
NAD is released by Myt in:
GERANYLGERANYLPIROPHOSPHATE is transformed to ABA that convertS NAD to cADPR
Sensitivity to ABA increasing and sensitivity to GA decreasing with hypoxia.
Quantifying the sensitivity of barley seed germination to oxygen, abscisic acid, and gibberellin using a population-based threshold model. 2008
ABA content remained constant after 48 h of incubation under air, while it increased dramatically in embryos incubated under hypoxia
Hypoxia interferes with ABA metabolism and increases ABA sensitivity in embryos of dormant barley grains. 2006

Abscisic acid human
Myristoylation of human LanC-like protein 2 (LANCL2) is essential for the interaction with the plasma membrane and the increase in cellular sensitivity to adriamycin. 2006
Moreover, we confirmed previous data that LANCL2 overexpression enhances the cellular sensitivity to the anticancer drug adriamycin and found that this sensitivity is dependent on the myristoylation and membrane association of LANCL2.
