Abstract

|
|
|
The biochemical change during regeneration of perilla callus were investigated by comparing total protein and lipid contents, protein band pattern in SDS-PAGE, and fatty acid composition in the calli cultured for various period(0, 1, 3, 5 and 6 weeks) Calli were induced from cotyledon and hypocotyl explants of peplants of perilla on perilla on MS medium containing BA(0.5 mg/L) and NAA(0.5mg/L). The protein contents reached the peak at 3 weeks after induction of calli, and then was decreased. Total lipid contents was decreased as the culture period increased. The band pattern of polypeptides showed that 30KD and 45KD polypeptides and 22KD and 45KD polypetides were major proteins in the cotyledon and hypocotyl explants, respectively. However increase of culture period only 30KD protein was highly accumulated.
