WebBlumeria graminis f.sp. hordei (syn. Erysiphe graminis f.sp. hordei). Control of B. graminis in barley is mainly achieved by fungicide treatment, but it is a problem to obtain effective control as the fungal population has the potential to develop tolerance against most used fungicides (De Waard et al., 1993). Alternatively, WebIn contrast with oomycetes, little is known about effector functions in true fungi. We used a bioinformatics pipeline to identify Blumeria effector candidates (BECs) from the obligate biotrophic barley powdery mildew pathogen, Blumeria graminis f. sp. hordei (Bgh). BEC1-BEC5 are expressed at different time points during barley infection.
