Overexpression of constitutive activation mutant of PtRabE1b confers salt tolerance in poplar. a Construction of a constitutively activation mutant of PtRabE1b at Q74L. b, c Growth status of wild type and two PtRabE1b(Q74L) overexpression lines (#11 and #13) under salt stress (0 mM, 50 mM and 100 mM NaCl). d-f Root number, average root length and total root length (n = 12). g Expression of selected co-expressed genes of PtRabE1b in wild type and PtRabE1b(Q74L) overexpression lines #11 and #13 under salt stress. Bars represent the mean ± SE of three independent experiments. * and ** represent significant differences at P < 0.05 and P < 0.01 compared with WT plants, respectively
