    • A method for deleting a region of DNA in a plant. In some embodiments, the method comprises transforming a plant with a nucleic acid molecule, wherein the nucleic acid molecule encodes one or more zinc finger nuclease(s) (ZFNs) operably linked to one or more tissue-specific promoter(s), e.g., a pollen-specific promoter. Methods include excising native genes in a plant. Accordingly, in some embodiments, ZFNs are engineered that recognize sequences that flank native plant genes. In further embodiments, ZFNs are expressed under the control of developmental stage-specific promoters, such that, for example, nucleic acid sequences are specifically excised in plants during relatively late stages of development. Nucleic acid molecules useful for carrying out disclosed methods and plants produced by the methods are included.
    • 一种删除植物中DNA区域的方法。 在一些实施方案中,所述方法包括用核酸分子转化植物,其中所述核酸分子编码与一个或多个组织特异性启动子可操作地连接的一个或多个锌指核酸酶(ZFN),例如, 花粉特异性启动子。 方法包括在植物中切除天然基因。 因此,在一些实施方案中,ZFN被设计为识别与天然植物基因相邻的序列。 在进一步的实施方案中,ZFN在发育阶段特异性启动子的控制下表达,使得例如在相对较晚的发育阶段在植物中特异性切除核酸序列。 包括用于实施所公开的方法的核酸分子和通过该方法生产的植物。

    • The subject invention provides novel amino acid sequences (including a consensus sequence) of the Avian Influenza A virus hemagglutinin protein. These newly constructed genes are designed to provide a broader spectrum of activity across the serotype family thus providing a basis for a vaccine that has broad heterologous disease protection. The novel genes have been further improved by the addition of strategic glycosylation sites into the amino acids sequences that they encode. These genes can also, optionally, be codon optimized for plant expression, inserted into the appropriate vector and cloned into plants for expression. Polypeptides produced by recombinant host cells or transgenic plants can also be used as source of antigen for the formulation of vaccines for the control of influenza in susceptible individuals. Additionally, transgenic plant material may also be used as source of antigen for the formulation of vaccines for the control of influenza in susceptible individuals.
    • 本发明提供禽流感A病毒血凝素蛋白的新型氨基酸序列(包括共有序列)。 这些新构建的基因被设计为提供跨血清型家族的更广泛的活性范围,从而为具有广泛异源疾病保护的疫苗提供基础。 通过在其编码的氨基酸序列中加入战略糖基化位点,进一步改善了这些新基因。 这些基因也可任选地优化用于植物表达的密码子,插入合适的载体中并克隆到植物中用于表达。 通过重组宿主细胞或转基因植物产生的多肽也可以用作疫苗来源,用于制定用于控制易感个体中的流感的疫苗。 另外,转基因植物材料也可以用作疫苗的来源,用于制定用于控制易感个体中的流感的疫苗。
