CucCAP scientists use multiplex system to monitor virus threats to melon crops

Featured Article

Multiple aphid- and whitefly- transmitted viruses are an increasing threat to melon production in the southwestern United States.  Often plants are infected by a mixture of different viruses, posing challenges for disease management and efforts to develop resistant varieties.  To help address this problem the Wintermantel lab in Salinas CA developed a multiplex single-step RT-PCR method to simultaneously test and differentiate among the among the different viruses.  Sampling of melon production regions in California and Arizona found that different combinations of viruses were dominant in fall vs. spring seasons, providing important information for disease management in areas impacted by cucurbit yellowing viruses.
