Two aminopeptidase I homologs convergently contribute to pathobiology of fungal entomopathogen Beauveria bassiana via divergent physiology-dependent autophagy pathways for vacuolar targeting.

ABSTRACT:

Introduction

In yeast, the cytoplasm-to-vacuole targeting (Cvt) pathway acts as a biosynthetic autophagy-related process, in which vacuolar targeting of hydrolase is mediated by the machineries involved in the selective autophagy. However, the mechanistic insights into vacuolar targeting of hydrolases through the selective autophagy pathway still remain enigmatic in filamentous fungi.

Objectives

Our study aims to investigate the mechanisms involved in vacuolar targeting of hydrolases in filamentous fungi.

Methods

The filamentous entomopathogenic fungus Beauveria bassiana was used as a representative of filamentous fungi. We identified the homologs of yeast aminopeptidase I (Ape1) in B. bassiana by bioinformatic analyses and characterized their physiological roles by g
