In agreement, the auxin-response reporter DR5 fusion was detected in Rhizobium infected root hairs as well as the auxin-responsive GH3.1 gene, suggesting a role for auxins in epidermal infections (Breakspear et al., 2014; Laplaze et al., 2015) (Figures 1 and 2). The gene discussed is TNFRSF10B; the disease is infection.
