Cell Wall Regeneration around Protoplasts Isolated from Convolvulus Tissue Culture.
Protoplasts of Convolvulus arvensis L. tissue culture regenerated a wall-like structure within 3 days in culture. Although unusually electron dense and atypically amorphous in the electron microscope, this structure could be digested with Myrothecium cellulase but was resistant to protease, a Rohm and Haas pectinase, and a beta-1, 3-exoglucanase just like the original wall. A cytochemical test ...
متن کاملSHOOT REGENERATION FROM PROTOPLASTS OF PENNISETUM AMERICANUM L (MIL CEREAL)
A finely dispersed cell suspension was obtained from embryogenic calli of two genotypes of pearl millet (Pennisetum americanum L. Mil cereal). Protoplasts isolated from both cell suspensions divided and produced globular embryoids and calli. On an agar medium, the embryoids were induced to form albino shoots or albino plantlet- like structures
متن کاملRegeneration of Fertile Barley Plants from Mechanically Isolated Protoplasts of the Fertilized Egg Cell.
A simple procedure is described for the mechanical isolation of protoplasts of unfertilized and fertilized barley egg cells from dissected ovules. Viable protoplasts were isolated from ~75% of the dissected ovules. Unfertilized protoplasts did not divide, whereas almost all fertilized protoplasts developed into microcalli. These degenerated when grown in medium only. When cocultivated with barl...
متن کاملSHOOT REGENERATION FROM SAFFRON PROTOPLASTS IMMOBILIZED IN Ca-ALGINATE BEADS
Saffron (Crocus sativus L.) protoplasts were isolated from the cells of a suspension culture or calli with a solution of Cellulase, Pectinase and Hemicellulase and embedded in Ca-alginate beads. They were cultured with or without nurse cells in MS medium supplemented with 2,4-D and 6-benzylaminopurine at 25°C. After several changes of medium, cell-clusters appeared on the surface of the Ca-algi...
متن کاملTransient Gene Expression in Protoplasts of Phaseolus vulgaris Isolated from a Cell Suspension Culture.
A cell suspension culture of Phaseolus vulgaris cv Negro jamapa was established. Protoplasts isolated from this culture are suitable for transient gene expression studies after DNA transfer by either electroporation or treatment with polyethylene glycol. The optimized conditions for both methods were established, taking into consideration expression and cell viability. We have investigated two ...
