Hypertrophy is linked to transcriptional cytokinin responses during Phtheirospermum infection in different host genotypes. (A) ARR5 expression relative to Arabidopsis ACT7 in shoots of host plants was quantified by qRT-PCR at 11 dpi of n = 3–7 independent experiments. (B) qRT-PCR expression analysis of host genes regulated by cytokinin relative to ACT8 in Col-0 (gray) and ahk3,4 (black) root segments above haustorium attachment sites at 11 dpi and control experiments (n = 3). All graphs show mean expression ± SD with ***P < 0.001; **P < 0.01; *P < 0.05, P > 0.05 was considered not significant (ns) by using a Student’s t test.
