영어 초록

Gene manipulation of Siberian wildrye grass through transgenic technology can modify grass feature for further improvement in the forage production. In order to optimize transformation conditions of Siberian wildrye grass, the effects of transformation efficiency was investigated with GUS gene. Seed-derived calli were infected and co-cultured with Agrobacterium tumefaciens carrying the binary vector pCAMBIA3301 encoding the GUS gene in the T-DNA region. The effects of several factors on transformation and the expression of the GUS gene were investigated. The highest transformation efficiency was obtained when embryogenic calli were inoculated with Agrobacterium strain EHA101 in the presence of 200 μM acetosyringone and coculture for 5 days. The present study was framed and materialized to standardize an efficient, high frequency and reproducible genetic transformation protocol for aromatic Siberian wildrye grass using Agrobacterium tumefaciens.
