Electroporation을 이용한 잔디(Zoysia japonica Steud.) 및 벼(Oryza sativa L.) 배발생세포로의 DNA 도입
DNA Delivery into Embryogenic Cells of Zoysiagrass(Zoysia japonica Steud.) and Rice(Oryza sativa L.) by Electroporation
초록
간편하면서도 효율적인 단자엽 식물의 형질전환 기법을 개발하기 위하여 배발생 세포를 직접 electroporation하여 DNA를 도입하는 실험을 벼와 잔디에서 실시하였다. 잔디는 수정 후 3주된 미숙배에서 캘러스를 유도하였으며, 2.4-D가 1 mg/L 함유된 액체 MS배지로 옮겨 진탕배양한 것을 electroporation 실험에 이용하였다. 벼는 20 mm 정도의 미숙화서 유래의 캘러스를 액체 N
To develop simple and efficient transformation methods of monocotyledonous plane, electroporation-mediated delivery of DNA into intact embryogenic cell clumps was investigated in zoysiagrass and rice. Calli of zoysiagrass, induced from 3-week-old immature embryos, were suspension-cultured in MS basic medium supplemented with 1.0 mg/t 2.4-D and used for elechuporation. Calli, derived from immature inflorescences of 20 mm lenth of rice, were also suspension-cultured on N6 basic medium supplemented with 1.0 mg/L 2.4-D. Suspension-cultured embryogenic cell clumps were electroporated in liqid MS medium added with a Plasmid DNA (30
