Roots of host plants elicit a local change in morphology in the hyphae of arbuscular mycorrhizal fungi, prior to the formation of appressoria. The elicited hyphae switch from their original branching pattern and apical dominance to differentiate in a new irregular, septate branching pattern with reduced inter-hyphal spacing. The extensive hyphal development associated with roots of host plants was shown to be due to the differential growth pattern described, and to precede the further cascade of events leading to appressorium formation and the development of a functional symbiosis.
在附着胞形成之前，宿主植物的根会引发丛枝菌根真菌菌丝形态的局部变化。被引发的菌丝从其原来的分支模式和顶端优势转变为以一种新的不规则、有隔膜的分支模式进行分化，菌丝间间距减小。与宿主植物根系相关的广泛菌丝发育被证明是由于上述不同的生长模式所致，并且先于导致附着胞形成和功能性共生体发育的一系列后续事件。
