The mechanisms by which plants sense environmental stresses, transduce signals into cells and Braam Research regulate cellular and organismal alterations are largely unknown.TCH genes of Arabidopsis We have taken a molecular approach to investigating these aspects of plant biology. The TCH genes of Arabidopsis are rapidly and strongly upregulated in expression in response to various environmental stimuli, including the seemingly innocuous stimulus of touch. These genes are powerful molecular tools for investigating how plants perceive environmental conditions and how they mount responses. We are investigating the cellular and genetic elements that control TCH expression and the biochemical and physiological functions of the TCH products. The TCH genes encode calmodulin, calmodulin-related proteins and a xyloglucan endotransglucosylase/hydrolase (XTH) predicted to act in modifying the plant cell wall. Current data support a hypothesis that the TCH proteins collaborate in the fundamental process of plant cell expansion.  Publications/Creative Works Click here to search for this faculty member's publications on PubMed.  Affiliations  Research Consortia John S.
