Fig. 2. Transcript abundances in whole seeds of the three Arabidopsis thaliana GID1 genes during germination.
A, The time course of endosperm rupture of A. thaliana (Col) seeds on medium without (CON) or with 10µM GA4+7 (GA) or 1µM ABA added. After-ripened seeds were incubated at 24 ºC in continuous light without preceding stratification. Mean values ± SE of 3x 50 seeds.
B, In silico analysis on GID1 transcript abundance during early germination of unstratified Arabidopsis (Col) seeds based on eFP-Browser microarray data; Relative expression values ± SD for AtGID1a (At3g05120), AtGID1b (At3g63010) and AtGID1c (At5g27320).
C, GID1 transcript abundance pattern determined by qRT-PCR in whole seeds of Arabidopsis (Col) at 30h, i.e. at 0% endosperm rupture for CON (see panel A). ddCt expression values relative to validated constitutive transcripts are presented. Medium additions as in A; Mean values ± SE of 4x >1000 seeds.
