The tgg1, single and tgg1 tgg2 double mutants showed morphological changes compared to wild-type plants visible as changes in pavement cells, stomatal cells and the ultrastructure of the cuticle.
Title: Arabidopsis myrosinases link the glucosinolate-myrosinase system and the cuticle.
Data indicate that loss of the basic helix-loop-helix transcription factor FAMA function abolishes myrosin idioblasts (MIs) fate as well as the expression of the myrosinase genes TGG1 and TGG2.
Title: Myrosin idioblast cell fate and development are regulated by the Arabidopsis transcription factor FAMA, the auxin pathway, and vesicular trafficking.
These results demonstrate that TGG1 and TGG2 have the ability to function in environments like the digestive tract of insect herbivores that are significantly different from the environment in a damaged plant.

TGG1 and TGG2 function redundantly downstream of ROS production and upstream of cytosolic Ca2+ elevation in abscisic acid and methyl jasmonate signaling in guard cells.
Title: Myrosinases, TGG1 and TGG2, redundantly function in ABA and MeJA signaling in Arabidopsis guard cells.
TGG1 showed striking abundance in the guard cell and tgg1 mutants were hyposensitive to abscisic acid inhibition of guard cell inward K(+) channels and stomatal opening, revealing TGG1 is required for key ABA responses of guard cells.
Title: Functional proteomics of Arabidopsis thaliana guard cells uncovers new stomatal signaling pathways.
