摘要: The MinE protein plays an important role in plastid division. In this study, the MinE gene was isolated from the cassava (Manihot esculenta Crantz) genome. We isolated high quality and quantity protoplasts and succeed in performing the transient expression of the GFP-fused Manihot esculenta MinE (MeMinE) protein in cassava mesophyll protoplasts. The transient expression of MeMinE-GFP in cassava protoplasts showed that the MeMinE protein was located in the chloroplast. Due to the abnormal division of chloroplasts, overexpression of MeMinE proteins in cassava mesophyll protoplasts could result in fewer and smaller chloroplasts. Overexpression of MeMinE proteins also showed abnormal cell division characteristics and minicell occurrence in Escherichia coli caused by aberrant septation events in the cell poles.
