| − | <p>Our modeling can be divided into four parts. Firstly, in order to enable our project to be applied in life, we design a device placed in soil, which can attract and kill nematodes by modified engineering bacteria inside. Secondly, assuming there is a farmland, we take advantage of nematodes’ movement analogue simulation to find the best position where the device should be placed and the best concentration of attracting substance. Thirdly, according to this concentration, we obtain the best size of the device by calculating. At last, we establish a database to enlarge applied range of our method to kill other pests. We would appreciate that new synthetic biological and environment-friendly methods can be shared and improved with the science researchers all over the world.</p>

| − | We found two kinds of toxic proteins that can kill nematodes specially—Bace16 and MpL—through reviewing literatures which confirmed the function of poison nematodes of these two proteins. We found the gene sequence of bace16(AAV3D0845) and the cDNA sequence of MpL(GeneBank accession number HQ449739) from the Genebank, and optimized the coded sequences in E.coli.

| − | <br/>We enlarge cultivated the standard LS expression bacteria (E.coli-BW2513-psb1c3) and expressed the objective produce (in contrast with empty vector). We did SDS-PAGE under the protocol mentioned above (reserve the homogenate as protein sample), no significant difference observed between the bands.

| − | <br/>In addition, the differences between bands of BW25113 and BL21 was obvious when run SDS-PAGE together whereas the objective band of BW25113 cannot be ensured.

Also, we changed the concentration of L-Ara and increased the concentration of running gel to 15% when running SDS-PAGE. Still, we failed to observe objective band at all the supernatant of bacterium, homogenate and supernatant of ultrasonic broken cells.

We extracted proteins to do SDS-PAGE, again finding no sign of rMpL expression.

| − | <p> 1. Place a glass funnel (d = 10~15 cm) on the funnel stand linked with about 10cm rubber tube which is furnished with a flatjaw pinchcock.
| + | |

| − | <p>2. Cut the soil sample into matchstick shape. Package 10 g(wet weight) with gauze and put it into the funnel, and then add water to immersion the sample.

| + | |
| − | <p>3. After 4~24 hr, nematodes leave the plant tissue and swim in the water and ultimately precipitate at the bottom due to their gravity and hydrotaxis.
| + | |
| − | </p>
| + | |
| − | <p>4. Open the flatjaw pinchcock, adopt about 5~15 mL liquid sample from the bottom which obtains most active nematodes of the soil sample. Check under the stereoscope and count nematodes, or centrifugate(1500 r) first and check the precipitation if the nematodes are too few.
