    • The present invention provides a bacterial host cell having improved cell permeability properties, the cell comprising an Orf18 gene or species homologue thereof, or a fragment or variant of the same encoding a polypeptide having the activity of the Orf18 gene product or species homologue thereof, wherein the gene, homologue, fragment or variant is under the control of an heterologous promoter (inducible or constitutively active) which permits sufficient expression of the gene, homologue, fragment or variant to increase the permeability of the cell wall. "Orf18 and the "orf18 gene" are also known as "CsiA" and the "csiA gene" respectively. In one embodiment, the host cell is a Lactococcus lactis cell in which a chromosomally-integrated Orf18 gene naturally present in the cell is inactivated. The invention further provides the use of such host cells in the production of polypeptides. In addition, the invention provides pharmaceutical compositions of the host cells and the use thereof for administering a bioactive agent to the human or animal body (for example, to the Gl tract).
    • 本发明提供具有改善的细胞渗透性的细菌宿主细胞,所述细胞包含Orf18基因或其物种同系物,或编码具有Orf18基因产物或其物种同系物的活性的多肽的片段或变体,其中 基因,同源物,片段或变体在异源启动子(可诱导或组成型活性)的控制下,其允许基因,同源物,片段或变体的足够表达以增加细胞壁的通透性。 “Orf18”和“orf18基因”也分别被称为“CsiA”和“csiA”。在一个实施方案中,宿主细胞是乳酸乳球菌细胞,其中天然存在于细胞中的染色体整合的Orf18基因被灭活 本发明还提供这种宿主细胞在多肽的制备中的用途。此外,本发明提供宿主细胞的药物组合物及其用于向人或动物体施用生物活性剂的用途(例如, Gl道)。

    • This invention relates to methods for producing, at a high frequency, transgenic plants that contain little if any vector sequences, have simple integration patterns, contain few copies of the transgene at each locus, express the transgene at all stages of development and do not exhibit transgene silencing. The method comprises introducing minimal transgene expression cassettes, which are substantially or totally devoid of vector sequences, by direct DNA transfer, preferably by particle or microprojectile bombardment. This invention also relates to transformed plant cells, the transgenic plants regenerated therefrom, and subparts of the transgenic plants produced by the methods of this invention. The invention also includes all progeny and subsequent progeny (i.e., all subsequent generations) derived from primary transformants through selfing or crossing.
    • 本发明涉及用于在高频率下生产含有少量任何载体序列的转基因植物的方法,其具有简单的整合模式,在每个基因座处含有少量拷贝的转基因,在发育的所有阶段表达转基因,并且不显示 转基因沉默。 该方法包括通过直接DNA转移,优选通过粒子或微粒轰击引入基本上或完全没有载体序列的最小转基因表达盒。 本发明还涉及转化的植物细胞,由其再生的转基因植物和通过本发明的方法生产的转基因植物的亚部分。 本发明还包括通过自交或杂交从原代转化体衍生的所有后代和随后的后代(即所有后代)。
