InnerPlant is an agtech company that engineers plant DNA to turn them into “living sensors”. When plants glow a certain color, this signals that it is stressed from lack of water, pests, or nutrient deficiencies. This helps farmers spot stressed plants much more quickly than they normally would be able to, and therefore have a better chance of mitigating crop loss.
Last week, The Spoon was given a virtual zoom tour of the InnerPlant facilities and shown the glowing plants under lasers. The company had examples of the two plant species it is currently working with, tomatoes and Arabidopsis. The colored light is not visible to the human eye, so Roderick Kumimoto, the Chief Science Officer of InnerPlant, used different laser pointers to demonstrate the glow. In the field, farmers use InnerPlant’s augmented reality system to photograph with an iPhone or iPad to detect glowing plants.
As you can see, the engineered plants look just like the regular non-engineered plants in normal lighting. Turn the lights off and point a laser at them, the engineered tomato and Arabidopsis plants have a yellow, red-orange, and green glow.
To create the living sensor plants, InnerPlant adds a fluorescent protein (which is safe for human consumption) into the plant’s DNA. Different colors signal different problems. If the farmer is using satellites or drones to view the plants from above, then up to three colors can be detected. From a ground-level view, upwards of seven to eight colors can be seen.
The companies first products are tomato and Arabidopsis plants that signal if they are under attack by fungus or pests. Currently, the company is working on commercializing InnerSoy plants. After that, they plan to develop cotton and corn versions of their glowing plants.
