To get in vivo evidences that apoplast calmodulin con 1d regulate plant growth and development process, a chimeric secretion form of calmodulin binding peptide, which contains a signal peptide, a calmodulin binding domain and a c - myc epitope was constructed. the chimeric gene was introduced into arabidopsis. it was expected that the overexpression of this chimeric protein could be secreted into cell wall and bound to apoplast calmodulin, which could reduce the apoplast calmoduin concentration to make an apoplast camodulin " antisense " plant. by observing the potential phenotype change of apoplast calmodulin " antisense " plant, the in vivo function of apoplast calmodulin on plant growth and developmental process could be speculated
但這些多是採用生理學手段和藥理學方法而得出的體外（ invitro ）實驗結果，為了取得質外體cam在植物生長發育過程中發揮重要作用的invivo實驗證據，根據動物中的一些研究方法，本實驗設計並構建了帶有信號肽、 cam結合肽（ can小肽） 、 epitope （ c - myc ）融合基因的載體，並將融合基因通過真空滲入法轉入擬南芥，預期過表達的融合蛋白將會被分泌到細胞外並與質外體cam相結合，這樣就會抑制質外體cam的功能，從而可以構建質外體cam的「反義」植株，通過觀察質外體cam 「反義植株」的表型改變，就可以推斷質外體cam在植物生長發育過程中的功能。 -
