Plant Regeneration from Protoplasts of Coriandrum sativum

Li Bao-ping, Zhang Jiang-tao, Chen Rou-ru. Hao Jian-ping and Guo Shuang-sheng   

Abstract: Calli produced from stem segments of seedling of Coriandrum satwum which were cultured on MS agar medium containing NAA 1.0mg/L. The embryogenic cell colony suspension was estabilished on MS liquid medium containing NAA 1.0mg/L%2,4-D 0.2mg/L+BA 0.5 mg/L. The cell suspension culture was used for protoplast preparation. Protoplasts were obtained in the enzyme mixture containing 2.0% Onozuka R-10, 1.0% pectinase, 0.5% snailase, 0.5% dextran sulfate potassium Salt, 0.6mol/L mannital CPW solution at pH 5.8 and 25℃. Cultured in a KM8P liquid medium containing NAA 1.0mg/L+2,4-D 0.2mg/L+6-BA 0.5 mg/L, glucose 0.4mol/L and CM 20mi/L; the protoplasts entered the stage of derision after three days, cell clusters formed in 10 days and calli formed after about 50 days. When the calli were transferred to MS agar medium containing many growth substances, they differentiated into embryoids, and then developed into plantlet with many green leaves and roots on the 1/2 MS agar medium.

Key words: Coriandrum sativum, Protoplast, Plant regeneration
