ABA Arabidopsis seed

Figure 5. Abscisic acid (ABA) contents in germinating Arabidopsis thaliana seeds and the effect of moist cold stratification.
(A) Important steps of ABA biosyntheses, degradation and signalling; see main text for details.
(B) Endogenous contents of ABA in germinating seeds and the effect of moist cold stratification. After-ripened seeds were incubated at 4 ºC in the dark which inhibits germination (cold stratification). Germination occurs during subsequent incubation at 22 ºC in the light and is completed by endosperm rupture. Data on seed ABA contents for drawing the diagram are from Chiwocha et al. (2005).
