Technical Abstract: Phytonematodes use a stylet and secreted effectors to invade host tissues and extract nutrients to support their growth and development. The molecular function of nematode effectors is currently the subject of intense investigation. In this review, we summarize our current understanding of nematode effectors, with a particular focus on proteinaceous stylet-secreted effectors of sedentary endoparasitic phytonematodes, for which a wealth of information has surfaced in the past ten years. We provide an update on the effector repertoires of several of the most economically important genera of plant-parasitic nematodes and discuss current approaches to dissect their function. Lastly, we highlight the latest breakthroughs in effector discovery that promise to shed new light on effector diversity across the phylum Nematoda.
