18941053 Piskurewicz U, Jikumaru Y, Kinoshita N, Nambara E, Kamiya Y, Lopez-Molina L: The gibberellic acid signaling repressor RGL2 inhibits Arabidopsis seed germination by stimulating abscisic acid synthesis and ABI5 activity. Plant Cell. 2008 Oct;20(10):2729-45. Epub 2008 Oct 21.

19556968 Piskurewicz U, Tureckova V, Lacombe E, Lopez-Molina L: Far-red light inhibits germination through DELLA-dependent stimulation of ABA synthesis and ABI3 activity. EMBO J. 2009 Jun 25;28(15):2259-2271.

This elicits a decrease in gibberellins (GA) levels and an increase in abscisic acid (ABA) levels.
We show that repression of germination by FR light involves stabilized DELLA factors GAI, RGA and RGL2 that stimulate endogenous ABA synthesis.

This study demonstrates that the ABA Insensitive 3 (ABI3) gene in the ABA signalling pathway and the RGA-like 2 (RGL2) and SPINDLY (SPY) genes in the GA signalling pathways all play important roles in the glucose-induced delay of seed germination.

Interestingly, NTL8 is significantly induced during cold imbibition, but the induction declines quickly in germinating seeds, like RGL2.

19704528 Kim SG, Park CM: Gibberellic acid-mediated salt signaling in seed germination. Plant Signal Behav. 2008 Oct;3(10):877-9.


We recently demonstrated that a membrane-bound NAC transcription factor, NTL8, mediates salt signaling, primarily through a RGL2-independent GA pathway, in regulating seed germination.
