The avocado fruit () has become a significant fruit in the human diet for its nutritional properties. However, the seed is a source of bioactive molecules and has been poorly utilized. Previously, we reported that the PaSn gene is expressed in the avocado seeds, a cysteine-rich antimicrobial peptide (GASA/Snakin), and demonstrated its antibacterial activity. In this work, we report the recombinant production of PaSn in the system and evaluate its antifungal activity against plant and human pathogen fungi. The recombinant peptide showed antifungal activity at 200 μg/mL against phytopathogens and and human pathogens and . Our results demonstrate the usefulness of a prokaryotic expression system for avocado antimicrobial peptide production. In conclusion, the snakin PaSn could be helpful in the control of postharvest avocado and other fruits' fungal diseases and human fungal pathogens.

Fungal contamination in drinking water has garnered considerable attention over the past few decades, especially considering the detrimental consequences of pathogenic fungal species on both human and animal health. The formation of biofilms by certain species is a considerable factor contributing to the emergence of severe fungal infections. This research was designed to isolate and identify fungi, particularly those capable of forming biofilms from 150 samples of drinking water sourced from various locations.

Background: Development of novel chiral antifungal agents for effective control of plant pathogens is urgently needed. In this study, a series of pyrazol-5-yl-benzamide derivatives containing chiral oxazoline moiety were rationally designed and developed based on molecular docking.
Results: The in vitro antifungal assay results indicated that compounds (rac)-4h (R = Et), (S)-4 h (R = S-Et) and (R)-4 h (R = R-Et) exhibited remarkable antifungal activities against Valsa mali with median effective concentration (EC) values of 0.

Emerging evidence indicates that autophagy is tightly connected to the endocytic pathway. Here, we questioned the role of presenilins (PSENs 1 and 2), previously shown to be involved in autophagy regulation, in the secretion of small endocytic-originating extracellular vesicles known as exosomes. Indeed, while wild-type cells responded to stimuli promoting both multivesicular endosome (MVE) formation and secretion of small extracellular vesicles (sEVs) enriched in canonical exosomal proteins, PSEN-deficient cells were almost unaffected to these stimuli.
