Plant-Parasitic Nematodes (PPNs) are a major concern for farmers and agricultural producers around the world, as they cause considerable economic losses and food insecurity worldwide. Peptides are short chains of amino acids having signaling properties, play a crucial role in various physiological processes in plants, including stress response, development, and pathogen defense. Recent studies revealed that plant-parasitic nematodes produce secreted peptide interact with plant receptor kinases and modify their activity to promote nematode infection and feeding by suppress plant immune responses to the nematodes. The CLE peptides are a family of small signaling molecules in plants they are perceived by specific receptor kinases in plant cells, triggers downstream signaling pathways to regulate plant development. The nematode secreted peptides are mimic to plant CLE peptides have been discovered in plants which are known to interact with specific receptor kinases in plant cells and trigger downstream signaling pathways that promote nematode parasitism and feeding. The identified nematode secreted peptides share similarity with plant CLAVATA3/ESR (CLE) peptides, but genomic analyses have also identified nematode secreted peptides homologous to other classes of plant peptide hormones, which are used by PPNs to counteract plant immunity. This review focuses on the recent discovery of secreted peptides by PPNs that mimic endogenous plant peptides to promote parasitism.
