Genes for calmodulin and calmodulin-related proteins in Arabidopsis are up-regulated by a variety of physical stimuli, which include rain, wind and touch [Braam and Davis (1990) Cell 60: 357]. We have isolated five genes for calmodulin (AtCAL1, 2, 3, 5, 6) and one gene for a calmodulin-related protein (AtCAL4) from an Arabidopsis genomic library. Touch stimulus of Arabidopsis plants induces the accumulation of mRNA transcribed from AtCAL4 and AtCAL5, but not from the other isolated genes. The two touch-inducible genes are arrayed in tandem with a short intergenic region of 700 bp but they show different organ-specific patterns of expression.
拟南芥中钙调蛋白及钙调蛋白相关蛋白的基因受多种物理刺激上调，这些刺激包括降雨、风及触摸[布拉姆和戴维斯（1990年）《细胞》60: 357]。我们从一个拟南芥基因组文库中分离出了五个钙调蛋白基因（AtCAL1、2、3、5、6）和一个钙调蛋白相关蛋白基因（AtCAL4）。对拟南芥植株的触摸刺激会诱导AtCAL4和AtCAL5转录的mRNA积累，但不会诱导其他分离出的基因转录的mRNA积累。这两个触摸诱导型基因以700 bp的短基因间隔区串联排列，但它们表现出不同的器官特异性表达模式。
