Suspension-cultured cells of Oryza sativa and Celosia cristata were cryopreserved by the pre-freezing method. Dimethyl sulfoxide (DMSO), which is often used as a cryoprotectant, is cytotoxic. Therefore, in this study, we examined the effect of carboxylate polylysine (PLL) as a cryoprotectant in replacement of DMSO. It was found that cryopreservation in Oryza sativa with 5% ethylene glycol and 3.5% PLL resulted in significantly higher survival rates than that with 5% (v/v) DMSO and 10% (w/v) glucose and in Celosia cristata with 10% (w/v) glucose and 3.5% (w/v) PLL resulted in nearly survival rates that with 5% (v/v) DMSO and 10% (w/v) glucose. Our results indicate that PLL is effective as a cryoprotectant for cryopreservation of cultured plant cells.
