We show that the CK receptors AHK3 and AHK4 of Arabidopsis thaliana are essential for symptom development, and that the CK perception machinery is induced upon infection, underlining its central role in the symptomatology. Three classical CKs [ isopentenyladenine, trans-zeatin, and cis-zeatin (cZ)] and their 2-methylthio (2MeS)-derivatives were identified by CK profiling of both the pathogenic R. fascians strain D188 and its nonpathogenic derivative D188-5. However, the much higher CK levels in strain D188 suggest that the linear plasmid is responsible for the virulence-associated production. All R. fascians CKs were recognized by AHK3 and AHK4, and, although they individually provoked typical CK responses.
