WebMar 1, 2005 · 4.3. Plating density and protoplast growth in culture. The final (overall) density of protoplasts in the culture medium (plating density) is crucial for maximising wall regeneration and concomitant daughter cell formation. Generally, the optimum plating density is in the range 5×10 4 –1×10 6 protoplasts ml −1. WebCocking (1960) first used enzymes to isolate higher plant protoplasts. He applied culture filtrates of a cellulolytic fungus Myrothecium verrucaria to release protoplasts from tomato root tips. Later, Takebe and co-workers succeeded in applying commercially available cell wall-degrading enzymes, Macerozyme and Cellulase Onozuka, to isolate ...
