Synthetic Intelligent Ranger E. coli for Nematodes.

BACKGROUND

Plant-parasitic nematodes which are ususlly too tiny to catch sight of, cause serious losses to agricultural crops worldwide. And over 5000 species of 200 genus can parasitize the roots, stems, leaves, flowers, buds and seeds of manifold plants widely.

BAIT & KILLER

In our project, we designed three modules to attract and poison plant-parasitic nematodes. The E.coli would express attractant to allure nematodes when exposed to light, and express toxin to kill them as a result of the promoter’s reverse in the dark.

DEVICE

Assuming there is a farmland, gas diffusion model and nematodes’ movement analogue simulation are used to find the best position where the device should be placed. And a database is built to enlarge the range of our application to kill more different pests.

POLICY & PRACTICE

According to our survey, the farmer did not realize the damage of nematodes and we gave some suggestions to them. We interviewed related experts, dropped in the countryside, analyzed the soil sample, communicated with other teams and did assistance.
