Factors, particularly reactive oxygen species, that resulted in the transition of the fungus from endophyte to necrotrophic parasite and the development of disease symptoms were investigated %K Ramularia collo-cygni %K Ramularia leaf spot %K Hordeum vulgare %K hemibiotroph %K senescence %K antioxidant system %K disease susceptibility %K non-functional chloroplasts %K endophyte %K necrotroph %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5838821/
