作为对喷水、深灌、风、触碰、伤害或黑暗的反应，拟南芥至少调节四个触碰诱导(TCH)基因的表达。刺激后10到30分钟，信使核糖核酸水平增加100倍。拟南芥植株在触碰的刺激下发育出较短的叶柄和花蕾。这种发育反应被称为触角形态发生。TCH-1基因编码拟南芥钙调蛋白，与小麦钙调蛋白有1个氨基酸的差异。TCH-2和TCH-3的氨基酸序列与钙调蛋白的同源性分别为44%和70%。拟南芥中这一钙调蛋白相关基因家族的调控表明，钙离子和钙调蛋白参与了环境信号的转导，使植物能够感知和响应环境变化。
In response to water spray, subirrigation, wind, touch, wounding, or darkness, Arabidopsis regulates the expression of at least four touch-induced (TCH) genes. Ten to thirty minutes after stimulation, mRNA levels increase up to 100-fold. Arabidopsis plants stimulated by touch develop shorter petioles and bolts. This developmental response is known as thigmomorphogenesis. TCH 1 cDNA encodes the putative Arabidopsis calmodulin differing in one amino acid from wheat calmodulin. Sequenced regions of TCH 2 and TCH 3 contain 44% and 70% amino acid identities to calmodulin, respectively. The regulation of this calmodulin related gene family in Arabidopsis suggests that calcium ions and calmodulin are involved in transduction of signals from the environment, enabling plants to sense and respond to environmental changes.
