Taking a Stab at Pierce’s Disease | Adventures in Genomics


Plants, like animals, depend on microbes to function to their fullest capacity. To understand more about plants, plant microbiomes, and plant disease, Jacques and Irene interviewed Caroline Roper from UC Riverside. Caroline’s research focuses on the relationships that perennial crop plants, like the cultivated grapevine, have with their associated microbes. Her goal is to define how the microbiome affects plant health and disease outcomes in real-world agricultural settings. In her interview, she describes how radicinin from the fungus Cochliobolus sp. inhibits Xylella fastidiosa, the causal agent of Pierce’s Disease, a devastating vascular disease that poses a great threat in grapevine cultivation.
