    • A gene amplification system based on plant viral genetic elements dramatically increases foreign protein production in plants. A safer and more economical production system for vaccines and antibodies in recombinant plants grown using agricultural practice is described. The high-level expression system uses the replicative process of a plant mastrevirus, exemplified by bean yellow dwarf virus (BeYDV). The expression system is preferably inducible to avoid interference with plant growth and development. Developmental cues, such as fruit ripening, are employed to trigger expression of the foreign protein using a tissue-specific promoter. A single, stably integrated expression cassette for foreign protein is replicated extrachromosomally in ripening fruit, forming hundreds of transcriptionally competent copies. Preferred plant hosts include tomato as a model system and soybean for production of large quantities of protein at high total protein levels.
    • 基于植物病毒遗传元件的基因扩增系统大大增加了植物中的外来蛋白质产量。 描述了使用农业实践生长的重组植物中更安全和更经济的疫苗和抗体生产系统。 高水平的表达系统使用植物重症病毒的复制过程,以豆黄矮病毒(BeYDV)为例。 表达系统优选可诱导以避免干扰植物生长和发育。 使用诸如果实成熟的发育提示来使用组织特异性启动子来引发外源蛋白的表达。 用于外来蛋白质的单一稳定整合的表达盒在成熟果实中被染色体外复制,形成数百个可转录的拷贝。 优选的植物宿主包括番茄作为模型系统,大豆用于生产高蛋白总量的大量蛋白质。
