The black currant ( L.), a member of the Saxifragaceae family's genus, has gained consumer and grower acceptance due to its high nutritional value and economic potential. However, powdery mildew, the primary leaf disease affecting black currants, significantly impacts growers and the industry. Developing varieties highly resistant to powdery mildew is currently considered the most scientifically sound solution. However, the black currant's physiological and disease resistance mechanisms post-infection by powdery mildew remain understudied, thereby impeding further breeding efforts. Therefore, this study aimed to elucidate the pathogenesis of powdery mildew in various susceptible varieties, post-infection physiological changes, and molecular mechanisms related to powdery mildew. This was achieved through phenotypic observation, physiological data analysis, transcriptomic analysis, and qRT-PCR-mediated gene expression analysis.
黑加仑（学名：Ribes nigrum L.），虎耳草科茶藨子属成员，因其高营养价值和经济潜力而获得消费者和种植者的认可。然而，白粉病作为影响黑加仑的主要叶片病害，对种植者和该行业产生了重大影响。培育对白粉病具有高度抗性的品种目前被认为是最科学合理的解决方案。然而，黑加仑在感染白粉病后的生理和抗病机制仍未得到充分研究，从而阻碍了进一步的育种工作。因此，本研究旨在阐明白粉病在各种易感品种中的发病机制、感染后的生理变化以及与白粉病相关的分子机制。这是通过表型观察、生理数据分析、转录组分析和qRT-PCR介导的基因表达分析来实现的。
