Resurrect Bio has developed a technique for improving the immune system of crops using gene editing. They plan to use this technique to create sugar beet lines that are resistant to an aphid that spreads virus yellows, which can cause crop yields to decrease by up to 50%. The project will consist of three parts: defining the aphid's virulence proteins, decrypting the sugar beet's immune hubs, and determining which virulence proteins from the aphid are subverting the crop's natural defense response. The success of the project will allow Resurrect Bio to identify the specific immune receptors needed to make sugar beet resistant to the aphid. Targeted editing of these genes by plant breeding companies would allow farmers to reduce the use of pesticides, whilst increasing the yield of their crops.

Resurrect Bio 开发了一种利用基因编辑来改善作物免疫系统的技术。他们计划利用这项技术培育能够抵抗传播黄化病毒的蚜虫的甜菜品系，这种蚜虫会导致作物产量下降高达 50%。该项目将由三个部分组成：定义蚜虫的毒力蛋白，解密甜菜的免疫中枢，以及确定蚜虫的哪些毒力蛋白正在破坏作物的自然防御反应。该项目的成功将使 Resurrect Bio 能够识别出使甜菜对蚜虫产生抗性所需的特定免疫受体。植物育种公司对这些基因进行有针对性的编辑将使农民减少农药的使用，同时提高农作物的产量。
