Thermoinhibition (imbibition at 32 [deg] C) or treatment with abscisic acid at a temperature optimal for germination (25 [deg] C) suppressed both germination and endosperm cell wall mannanase activity, whereas alleviation of thermoinhibition with gibberellic acid was accompanied by significant enhancement of mannanase activity.

We report here that, in addition, phytochrome stimulates the sensitivity of the seeds to gibberellic acid (GA).
The phytochrome-induced signal is produced in the embryo and enhances the stimulus by GA of embryo growth potential (EGP) and the promotion of the expression of proteins thought to participate in ME weakening: endo-beta-mannanase (EC 3.2.1.78), endo-beta-mannosidase (EC 3.2.1.25) and expansin.

In both mutant and wild-type intact tomato seeds, LeGAMYBL1 expression increases during germination, is upregulated by gibberellic acid (GA (3)), and declines thereafter.
