Figures & data

Figure 1. Model for the sCvt pathway function during conidial dormancy in B. bassiana. Upon maturation, conidia enter a stage of dormancy and employ autophagy to safeguard cell longevity and vitality. During germinating, autophagy participates in conidial recovery from dormancy in this fungus. BbATG8 produces two isoforms, i.e., BbAtg8-α and BbAtg8-β. BbAtg8-α meditates BbApe4 transport into the vacuole via direct physical interaction. In the vacuole, BbApe4 undergoes processing that lead to its maturation into the active form (BbApe4*).
