PanSYMRK ectopic expression induces spontaneous nodulation in Parasponia andersonii. (A, B) Bright-field A and green fluorescent image B of P. andersonii A. rhizogenes-transformed roots expressing GFP and PanSYMRK under control of the pLjUBI1 promoter showing spontaneously formed nodule-like structures (6 weeks post planting). C Relative gene expression of PanSYMRK in P. andersonii A. rhizogenes-transformed roots containing an empty vector (EV) or pLjUBI1:PanSYMRK (n = 3). D Longitudinal section of a spontaneously formed nodule-like structure visualizing cortical and pericycle cell divisions
