| Abstract: | Objective] To obtain high yields of Nicotiana benthamiana leaf protoplast.Method] Different enzyme concentration and digestion time was applied in the experiment on the basis of the predecessors＇experiment,for further exploration of better isolation conditions.And on this basis,a further study on its application in protein interaction was conducted through the bimolecular molecular fluorescence complementation（BiFC） experiments.Result] The results show that,the Nicotiana benthamiana leaf protoplast were prepared under the condition that the cellulase concentration was 1.3％,the macerozyme concentration was 0.4％,the pectinase concentration was 0.3％,enzymatic hydrolysis time was 4 hours and the reaction temperature was 28 degrees,then in simple purification,we obtained the highest yields of complete protoplasts and the celludar debris and impurities are minimal.Conclusion] The method provides important technique reference for fluorescent protein research in tobacco leaf. |
