On the Cover: Cyst nematodes infect plant roots and induce the formation of a feeding site (syncytium) from which the nematodes feed. The cover image shows female cyst nematodes (dark ovals) that have induced a large syncytium (swollen areas) in Arabidopsis roots. Normal roots are visible in the background. The update by Gheysen and Mitchum [2019;179(4):1212-1226] provides an overview on how plant-parasitic nematodes modulate phytohormone and peptide hormone pathways for the establishment of feeding sites.
