- 論文の詳細を見る
Protoplasts of Undaria pinnatifida and Petalonia binghamiae were cultured for two and one months, respectively, in the presence of various levels of Mg. Under Mg-free conditions in ASP12NTA medium all protoplasts died. The percentage of filaments per surviving protoplast of U. pinnatifida increased from 0.47% in 50mM Mg to 5.33% in 200mM Mg. Under these conditions the cell number per filament also increased from 154 to 513. The percentage of filaments per surviving protoplast of P. binghamiae increased from 77% in 50mM Mg to 95% in 150mM Mg, while the number of cells per filament increased from 5.8 to 60.8. At concentrations higher than 100mM Mg, the Mg and chlorophyll a concentrations were almost equal to those in the thalli.
