Percent root length colonization of wild-type hairy roots transformed with empty vector (EV), and of ein2a-2 ein2b-1 hairy roots transformed with EV, or with the carboxy terminus of EIN2B expressed under the control of the indicated promoters. Statistics: Individual data-points and mean ± SE are shown. N = 7 for EV/WT, 13 for EV/ein2a ein2b, 8 for pUbiquitin, 9 for pEpidermis, 15 for pSbtM1, 18 for pCortex, 17 for pPT4; Kruskal-Wallis test (Kruskal-Wallis H statistic = 44.55 for total, 33.90 for arbuscules, 34.63 for vesicles) with Dunn’s posthoc comparison. Asterisks denote significance: * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001.
