"Plant-parasitic nematodes (PPNs) secrete an array of molecules that can lead to their detection by or promote infection of their hosts. However, the function of these molecules in plant cells is often unknown or limited to phenotypic observations. Similarly, how plant cells detect and/or respond to these molecules is still poorly understood. Here, we highlight recent advances in mechanistic insights into the molecular dialogue between PPNs and plants at the cellular level. New discoveries reveal a) the essential roles of extra- and intracellular plant receptors in PPN perception and the manipulation of host immune- or developmental pathways during infection and b) how PPNs target such receptors to manipulate their hosts. Finally, the plant secretory pathway has emerged as a critical player in PPN peptide delivery, feeding site formation and non-canonical resistance."
