Names
Ca. Phytoplasma pruni
Abstract
Stone fruits are a multibillion-dollar industry for the United States and Canada, one that has repeatedly suffered significant economic losses due to outbreaks of the X-disease phytoplasma (‘ Candidatus Phytoplasma pruni’) over the last century. Orchards and entire production areas have been abandoned, with corresponding losses to growers, fruit packers, and consumers. The most recent outbreak, in the U.S. Pacific Northwest, resulted in an estimated $65 million (USD) loss in revenue between 201

Effect of ‘Candidatus Phytoplasma pruni’ Infection on Sweet Cherry Fruit

Citation

Names
Ca. Phytoplasma pruni
Abstract
In sweet cherry (Prunus avium), infection by ‘Candidatus Phytoplasma pruni’ results in small fruit with poor color and taste, rendering the fruit unmarketable. Yet the disease pathology is poorly understood, particularly at the cultivar level. Therefore, in this study we examined the physiological effects of Ca. P. pruni infection across a range of cultivars and locations in eastern Washington. We found that infection could be separated into early and established stages based on pathogen titer,
