A rice α-amylase 3D system, which is induced sucrose starvation, has been previously reported to generate a good yield of recombinant protein in transgenic rice cell suspension culture. However, this induction system was high produced not only foreign protein but also undesirable proteins, rice α-amylase and cysteine proteinase (CysP), into the culture medium. A rice α-amylase is a dominant protein, with 43% of total secreted proteins and CysP was a major secreted protease in rice cell suspension cultures following induction via sugar depletion. Increasing the yield of recombinant proteins, protecting the produced proteins from protease, and diminishing expensive protein purification steps are important research goals in plant biotechnology. In the present study, rice amylase and CysP genes were eliminated almost completely via RNA interference (RNAi) technology to develop rice cells as a more efficient foreign protein expression system. The effects of RNA interference were characterized at both SDS-PAGE and Western blot analysis against CysP antibody and quantitative real-time RT-PCR analysis. Dependent upon the amylase and CysP ihpRNAi line, amylase and CysP decreased by approximately 90% at both the proteins and mRNA levels. However, the phenotype of ihpRNAi lines was not distinguishable from wild-type rice plants under in vitro and ex vitro growth conditions.
