Despite intensive investgation on the detection . localization , biological roles and signal transduction pathway of extracellular cam in plants , the mechanism by which extrallular cam is activated by ca2 + has been unclear , manily because of specific of extrallular milieu
已经证实，植物体普遍存在胞外钙调素，它可能作为一种广谱性多肽第一信使在细胞外产生多种生物学功能，并具有跨膜及胞内信号转导机制。
The results obtained in our laboratory in the past decade years showed , apoplast calmodulin in plant kingdom may regulate a lot of growth and development process of plant , such as accelerating the proliferation of angelica dahurica suspension cells and the proplast cell regeneration , startup the pollen germination of many plants " pollen and accelerating the elongation of the pollen tube , stimulating the redox of corn root " s cell , inducing the expression of light independent rbss gene , and participating in the regulation of the restraining function of al ~ ( 3 + ) to pollen tube germination
我室多年的研究结果表明，植物质外体cam可能做为多肽第一信使调节着植物体诸多的生长发育过程：如促进白芷悬浮细胞的细胞增殖和原生质体壁再生，启动并促进多种花粉的萌发和花粉管的伸长，刺激玉米根细胞的氧化还原反应，诱导rbcs基因光不依赖的表达，以及参与调节胞外al ~ ( 3 + )对花粉萌发的抑制效应等。
