Cyst nematodes are obligate biotrophs that induce the formation of a hypertrophied and hypermetabolic syncytial-feeding site in roots of the host plants. Cytokinin signaling is activated at the site of infection and contributes significantly to the formation of syncytium. Here, we describe a protocol for visualizing cytokinin signaling activation in Arabidopsis upon infection with cyst nematode Heterodera schachtii using promoter reporter lines, TCSn:GFP and ARR5:GUS.
