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].
