English The growth of microorganisms in planta is often categorized based on their methods of nutrient acquisition and the physical appearance of symptoms on the host. For example, biotrophs thrive on living tissue while necrotrophic pathogens often quickly lyse cells to access nutrients. Hemibiotrophs are pathogens that initially feed on living host tissue without causing visible symptoms prior to switching to necrotrophy. During infection of wheat, the pathogen Zymoseptoria tritici undergoes a prolonged and asymptomatic phase during which it grows slowly and protects itself from host defenses prior to eliciting a strong necrotic response. However careful analyses of the asymptomatic phase indicate that the pathogen does not alter host growth, casting doubt on the biotrophic nature of this asymptomatic period. Consequently, we question whether Z. tritici is correctly defined as a hemibiotroph.
