    • The invention provides a system for monitoring the bioavailability and/or toxicity of contaminants in the environment. The system includes plant biosensors that indicate the presence of contaminants, such as, for example, volatile organics or heavy metals, using an in situ monitoring approach. The plant biosensors are genetically engineered to exhibit a change in color phenotype under the control of promoter elements that are selectively responsive to the presence of a particular contaminant. The plant biosensing system provides a cost-effective approach to monitoring large and remote territories with high-spatial resolution. The transgenic plants can also be placed at strategic locations, before, during and after remedial activities at a site.
    • 本发明提供了一种监测环境中污染物的生物利用度和/或毒性的系统。 该系统包括使用原位监测方法指示污染物(例如挥发性有机物或重金属)的存在的植物生物传感器。 植物生物传感器被遗传工程化以在选择性地响应特定污染物的存在的启动子元件的控制下表现出颜色表型的变化。 植物生物传感系统提供了一种具有成本效益的方法来监测具有高空间分辨率的大型和偏远地区。 转基因植物也可以在一个地点的补救活动之前,之中和之后的战略地点放置。
