Stable expression of aquaporins and hypoxia-responsive genes in adventitious roots are linked to maintaining hydraulic conductance in tobacco (<i>Nicotiana tabacum</i>) exposed to root hypoxia - Fig 2

Root porosity of adventitious (ARs) and lateral roots (LRs) (A) and hydraulic conductance (Kr, B) of tobacco plants subjected to aerated or root oxygen deprivation (hypoxia) treatments for one week, and ATP concentration of ARs and LRs (C) after two days and one week of treatment. Means ± SE (n = 4–6 for porosity test, n = 6 for Kr and n = 3 for ATP assay) are shown. Different letters above the bars indicate statistically significant differences determined by the Tukey’s test after one-way ANOVA (P ≤ 0.05).
