Polyribosomes (polysomes) , active in an amino acid incorporation system in vitro, were isolated from tobacco leaf protoplasts. A comparison of polysome profiles indicated that the polysome/ monosome ratio is greatly decreased in isolated protoplasts as compared to the intact leaf. In isolated prot

โฆ Synopsis
Mature leaves of Secale cereale cut into narrow strips and incubated for 18 h in a mixture of cellulase (Meicelase) and pectinase (Pectinol R10) produced quantities of protoplasts. Under the same conditions leaves of Triticum aestivum, Hordeum vulgare and Avena sativa also produce protoplasts but in lower yields. The wheat and rye protoplasts in culture appear to regenerate a cell wall but only a very small proportion undergo cell division.

Yields of 106-108 peach mesophyll cells and protoplasts-gfw -1 were obtained depending on factors such as digesting enzymes, and leaf size. Onozuka R-10 (2%) in combination with Macerase (0.5%) was found best for protoplast isolation and mediocre for cell isolation among several enzyme combinations
