智慧农业背景下的纳米智能作物构建

Construction of Nanosensor-enabled Smart Plants in the Context of Smart Agriculture

智慧农业是未来农业的发展方向之一。而通过应用纳米感应元件构建纳米智能作物则可能是智慧农业的一种实现形态。文章详细地介绍了利用纳米感应元件构建纳米智能作物的构想和工作原理,并以能特异识别葡萄糖和H_(2)O_(2)的纳米感应元件为例,简要描述了其改造后的植物可实时监测葡萄糖变化规律和不同胁迫下(强光、紫外和Flg_(22)的H_(2)O_(2)变化规律,展示了纳米智能作物应用到作物胁迫早期诊断乃至智慧农业中的良好潜力。然后,文章从物联网及5G的角度,探讨了一些把纳米智能作物整合到智慧农业中的可能方式。总之,通过纳米感应元件构建纳米智能作物将会是助力智慧农业发展的一个备选方案。

Smart agriculture is a hotspot for agricultural production in future.Nanosensor-enabled smart plant could be an option for smart agriculture.In this review,we illustrated the idea of how to use nanosensors to engineer smart plant.The studies used nanosensors which are specific to glucose and H2O2 are further described in details.The plants engineered with glucose nanosensors showed the ability to monitor the changes of leaf glucose level in a real time way.Also,the plants engineered with H_(2)O_(2)nanosensors are able to track the changes of H_(2)O_(2)level under high light,UV and Flg_(22)stresses.It showed potential to use nanosensor-enabled smart plant in early stress detection and smart agriculture.Furthermore,we discussed the possible pathways to integrate nanosensor-enabled smart plant to smart agriculture from the viewpoint of Internet of Things and 5G.Overall,nanosensor-enabled smart plant could be an approach to facilitate the development of smart agriculture.
