ABI5 Is Downregulated in Germinating After-Ripened sly1 Seeds.
(A) Protein gel blot analysis of ABI5, RGL2, GAI, and RGA protein levels in sly1-10 seeds freshly harvested (before after-ripening) in the absence (normal [N]) or presence of 50 μM GA. Plant material was harvested at 48 and 120 h after seed imbibition. DS, dry seeds. Ponceau S staining is shown as a loading control.
(B) Same as in (A) using sly1-10 seeds after-ripened at room temperature for 1 year.
