    • Plant tissue specific gene expression by way of repressor-operator complexes, has enabled outcomes including, without limitation, male sterility and engineered plants having root-specific gene expression of relevant proteins to clean environmental pollutants from soil and water. A mercury hyperaccumulation strategy requires that mercuric ion reductase coding sequence is strongly expressed. The actin promoter vector, A2pot, engineered to contain bacterial lac operator sequences, directed strong expression in all plant vegetative organs and tissues. In contrast, the expression from the A2pot construct was restricted primarily to root tissues when a modified bacterial repressor (LacIn) was coexpressed from the light-regulated rubisco small subunit promoter in above-ground tissues. Also provided are analogous repressor operator complexes for selective expression in other plant tissues, for example, to produce male sterile plants.
    • 通过阻遏物 - 操作复合物的植物组织特异性基因表达,已经实现了包括但不限于雄性不育和具有相关蛋白质的根特异性基因表达的工程植物从而清除土壤和水中的环境污染物的结果。 水银超累积策略要求汞强反应酶编码序列强烈表达。 肌动蛋白启动子载体,A2pot,被设计成含有细菌lac操纵子序列,在所有植物营养器官和组织中指示强表达。 相比之下,当修饰的细菌阻遏物(LacIn)从地上组织中的光调节的rubisco小亚基启动子共表达时,来自A2pot构建体的表达主要限于根组织。 还提供了用于在其他植物组织中选择性表达的类似的阻遏物操纵子复合物,例如产生雄性不育植物。

    • The present disclosure provides methods, recombinant DNA molecules, recombinant host cells containing the DNA molecules, and transgenic plant cells, plant tissue and plants which contain and express at least one antisense or interference RNA specific for a thiamine biosynthetic coding sequence or a thiamine binding protein or a thiamine-degrading protein, wherein the RNA or thiamine binding protein is expressed under the regulatory control of a transcription regulatory sequence which directs expression in male and/or female reproductive tissue. These transgenic plants are conditionally sterile; i.e., they are fertile only in the presence of exogenous thiamine. Such plants are especially appropriate for use in the seed industry or in the environment, for example, for use in revegetation of contaminated soils or phytoremediation, especially when those transgenic plants also contain and express one or more chimeric genes which confer resistance to contaminants.

    • The present invention provides nucleic acid sequences encoding a metal ion resistance protein, which are expressible in plant cells. The metal resistance protein provides for the enzymatic reduction of metal ions including by not limited to divalent Cu, divalent mercury, trivalent gold, divalent cadmium, lead ions and monovalent silver ions. Transgenic plants which express these coding sequences exhibit increased resistance to metal ions in the environment as compared with plants which have not been so genetically modified. Transgenic plants which are resistant to organomercurials including alkylmercury compounds, among others, are provided by the further inclusion of plant-expressible organomercurial lyase coding sequences. Furthermore, these transgenic plants which have been genetically modified to express the metal resistance coding sequences of the present invention can participate in the bioremediation of metal contamination via the enzymatic reduction of metal ions. Transgenic plants resistant to organomercurials can further mediate remediation of alkylmercury compounds in the environment by causing the freeing of mercuric ions and the reduction of the ionic mercury to the less toxic elemental mercury.
