Researchers uncover how infections combat plant immune responses

...hy CTV is capable of such destructive effects. One approach for the control of CTV in a number of labs is to genetically engineer virus-resistant citrus trees. "Our findings will help improving the efficacy of this approach, e.g., by directly targeting the CTV suppressor genes," Ding said. "Our work indicat...
