Fungal Tip Growth

fungal tip growth model Fungal Tip Growth Characterization of cytoplasmic Ca2+ has identified at least two mechanisms associated with the process of hyphal growth. One involves Ca2+ influx at the growing tip (Saprolegnia). The other involves internal generation of a tip-high Ca2+ gradient (Neurospora). In both cases, a tip-high Ca2+ gradient is required for hyphal growth. Our most recent model of Ca2+ regulation and ion transport during Neurospora hyphal growth is shown. We are now exploring the role of turgor in hyphal tip growth. Movie of Neurospora crassa tip growth [22.4 MB]
