Check out work by Janet Bramm. She had an article in cell showing that
mechanical stimulation of Arabidopsis resulted in increased calmodulin
production ( which I can imagine might be related to increased polysaccaride
production and therefore cell wall stuff). The first article was in 
Cell about 
late 1989, I think
