Microtubule cytoskeleton plays an important role in cell division,differentiation,cell morphology decision,introcellular material transportation and other physiological activities.Performing those function depends on tubulin,microtubule-associated proteins(MAPs),correlated kinase and phosphate(ester) enzyme.In this article,GFP-TUA-6 and TUA-6-GFP gene were transferred into tobacco cotyledon mediated by Agrobacterium tumefaciens.Transformed lines were generated by the optimized genetic transformation system.It was proved that GFP-TUA-6 and TUA-6-GFP gene had been integrated into the tobacco genome by PCR detection and Southern blot analysis.The observation of laser scanning confocal microscope showed that GFP-TUA-6 protein was mainly located in cortical microtubules,while TUA-6-GFP protein was mainly located in cytoplasm and cortical microtubules,which provide a fundament for studying the dynamics activity of microtubule in cell morphogenesis.
