以广东籼稻良种秋桂矮11为材料,切取11d苗龄的叶基和叶鞘,游离原生质体;以台北309悬浮细胞为饲养层,放在饲养层顶部滤膜上培养,用N6+2,4-D1.5mg.L-1、玉米素0.2mg.L-1、水解蛋白500mg·L-1+葡萄糖0.5mol·L-1+C.15%琼脂糖半凝固培养基。5-7d后原生质体第一次分裂,秋桂矮11分裂频率可达27%:25~30d形成小细胞团,逐步降低葡萄糖的含量,从0.5mol·L-1下降至0.2mol·L-1,促进细胞持续分裂,待愈伤组织达到1~2mm时,转入增殖和分化培养基;60~70d后,秋桂矮11获得再生植株。另一品种SP60细胞团未见分化。
The leaves and leaf sheaths of 11-day-old seedlings and free protoplasts were obtained from the autumn indica rice variety Guiqian 11 in Taipei. The suspension cells of Taipei 309 were used as the feeder layer and cultured on the top membrane of the feeder layer with N6 + 2,4-D1. 5mg. L-1, zeatin 0.2mg. L-1, hydrolyzed protein 500 mg · L-1 + glucose 0.5 mol·L-1 + C. 15% agarose semi-coagulation medium. After 5-7 days, the protoplasts split for the first time, the split frequency of Qiu Gui short 11 was up to 27%. Small cell mass was formed from 25 to 30 days and the glucose content gradually decreased from 0.5 mol·L-1 to 0.2 mol·L-1 -1, to promote continuous cell division, to be callus reached 1 ~ 2mm, transferred to proliferation and differentiation medium; 60 ~ 70d, Qiu Gui short 11 regenerated plants. Another species of SP60 cell mass did not differentiate.
