    • Constructs and methods are provided for expressing peptides derived from eukaryotic organisms in plant plastids. Constructs have a promoter functional in a plant plastid, a DNA sequence encoding a peptide derived from an eukaryotic organism and a transcription termination region. Other elements include a selectable marker for selection of plant cells comprising a plastid expressing the marker and DNA regions of homology to the genome of the plastid and optionally a ribosome binding site joined to the promoter. By methods using such constructs high levels of eukaryotic peptides, such as mammalian proteins, are produced in a plant cell by growing plant cells under conditions whereby the DNA encoding sequences are expressed to produce eukaryotic peptide in said plastid.
    • 提供构建体和方法用于表达在植物质体中衍生自真核生物的肽。 构建体在植物质体中具有功能的启动子,编码来自真核生物的肽的DNA序列和转录终止区。 其他元件包括用于选择植物细胞的选择性标记,其包括表达标记的质体和与质体的基因组同源的DNA区以及任选的与启动子连接的核糖体结合位点。 通过使用这种构建体的方法,通过在条件下培养植物细胞,在植物细胞中产生高水平的真核肽,例如哺乳动物蛋白质,由此DNA编码序列被表达以在所述质体中产生真核肽。
