Actin , the major component of the dynamic microfilament cytoskeleton system , exists in nearly all eukaryotic cells and plays essential roles in cellular activities 摘要肌动蛋白在真核生物中广泛存在，由肌动蛋白参与形成的动态微丝骨架系统是细胞生命活动的基础。

The fusion gene ofgfp : mtn ( mtn is binding domain of microfilament binding protein talin , which can show the microfilament in living cell ) was transferred to arabidopsis thaliana . stable expression of gfp - mtn can visualize the actin cytoskeleton in different types in living cells without affecting cell morphology and function 将gfp : mtn ( mtn是微丝结合蛋白talin的微丝结合域，可以显示活体细胞中微丝的结构)导入拟南芥后，发现表达的融合蛋白能够标记微丝骨架，同时又不影响植物细胞的正常形态和功能。
