Abstract
The TCH genes of Arabidopsis were discovered as a consequence of their unusual upregulation of expression in response to mechanical stimuli, such as touch and wind. However, expression of these genes is also regulated by seemingly unrelated types of environmental stimuli, including darkness and temperature shifts, and by auxin and brassinolide. Here, we review characteristics of TCH gene expression and propose the hypothesis that regulation by all the diverse stimuli occurs in response to changes in mechanical strain perceived at the plasma membrane and/or cell wall. Upregulation of gene expression may serve to recruit the TCH gene products for functions in cellular mechano-homeostasis.
