RNA-seq profiling of early oak (Quercus robur) defense responses to Erysiphe alphitoides
Powdery mildew caused by Erysiphe alphitoides is a major foliar disease of European oaks. In this study, RNA sequencing was used to characterize early transcriptional responses of pedunculate oak (Quercus robur) leaves at 30 hours post inoculation with the pathogen. Detached leaves from healthy seedlings were inoculated with Erysiphe alphitoides or mock treated, and gene expression changes were analyzed to identify early defense related signaling pathways. The dataset provides a resource for understanding early host pathogen interactions in oak and for identifying candidate molecular markers associated with powdery mildew response.
