PcOSM have shown significant inhibitory activity against <i>P. capsici</i>, which is one of the most devastating pathogens infecting chilli crops [1].  Also, it has shown inhibitory activity against other fungal pathogens as <i>Fusarium oxysporum</i> [3]. Several experiments suggest that the mechanism of action of this osmotin is membrane permeabilization due to the positive charge of the osmotin [3]. Also, it has been hypothesized that the fungal inhibition shown by osmotin is due to the induction of ROS production [1].

This peptide has also attracted attention as it has shown similarity in functionality to adibonectin, making it also a molecule with therapeutic potential [1, 3, 4]. In addition, it has shown neuroprotective activity and has shown anti-atherosclerotic effects in rat studies [5, 6].

PcOSM: An osmotin from Piper colubrinum (An antimicrobial peptide)

This osmotin (PcOSM) is a plant defense protein with a molecular weight of ~25 kDa. PcOSM belongs to pathogenesis related-5 (PR-5) family, which is accumulated in response to both biotic and abiotic stresses [1]. This osmotin has exhibited significant inhibitory activity against the oomycete pathogen Phytophthora capsici. This peptide is able to inhibit fungal growth through inhibition of hyphal growth, spore germination, spore lysis, and reduction in viability of spore [2].
