Structural studies on cell wall biogenesis-I: A method to produce high-quality protoplasts from alga Micrasterias denticulata, an emerging model in plant biology

Micrasterias denticulate is a freshwater unicellular green alga emerging as a model system in plant cell biology. This is an algae that has been examined in the context of cell wall research from early 1970s. Protoplast production from such a model system is important for many downstream physiological and cell biological studies. The algae produce intact protoplast in a straight two-step protocol involving 5% mannitol, 2% cellulysin, 4mM calcium chloride under a temperature ramping strategy. The process of protoplast induction and behavior of protoplast was examined by light microscopy and reported in this study.
