Z ü st's team grew the model plant Arabidopsis thaliana with the genes for trichomes ( leaf hairs that discourage herbivores) and glucosinolate ( a chemical toxic to certain pests) disabled.

It is well known that TTG1/ GL3/ GL1 protein complex activates the expression of downstream gene GL2, ultimately leading such epidermal cells to differentiating into trichomes.

研究发现，在拟南芥表皮毛分化的过程中，TTG1/GL3/GL1等组成蛋白复合体，激活下游GL2的表达，最终使表皮细胞分化为表皮毛。

The effect of glandular trichomes may depend on the nature of the exudate.
