摘要: Arnebia euchroma callus, obtained from the root cell culture of an Iranian native specimen, has gained a doubling time 63 H after regular subculturing on Linsmaier-Skoog (LS) medium containing sugar (50 g/L), 2,4-dichlorophenoxyacetic acid (10(-6) M), and kinetin (10(-5) M) under darkness at 25°C. Despite observed somaclonal variations, peroxidase production by A. calli been stable over 4 years aforementioned conditions. Isoelectric focusing experiments revealed that partially purified peroxidases (AePoxs) are mainly anionic with pI values about 5.5 6.6. AePox reaches its optimal activity 55°C pH 7.5. Results various kinetic studies suggest belongs to type III plant no for oxidation 3-indoleacetic acid, but seems play role in lignin biosynthesis H(2) O(2) regulation during proliferation cells LS medium. Comparing biochemical properties horseradish view ease solid culture, callus could be considered as source some biotechnological applications.
