Quercus robur leaf transcriptomes. Quercus robur strain:DF159

The root-rot pathogen Phytophthora quercina is a key determinant of oak decline in Europe. Microcuttings of pedunculate oak Quercus robur undergo an alternating rhythm of root and shoot growth. Inoculation of mycorrhizal (Piloderma croceum) and nonmycorrhizal oak roots with P. quercina was performed during two growth phases, that is, root flush (RF) and shoot flush (SF). Gene expression of source leaves in RF and sink leaves in SF were analyzed by RNA sequencing to investigate the oak's gene expression response to the root-rot pathogen, and how it is modified by the interaction with an ectomycorrhizal fungus.
