Fig. 1 in Zinc uptake and HMA4 activity are required for micro- and macroelement balance in tobacco (Nicotiana tabacum)

Fig. 1. (a) Relative element contents of HMA4-impaired plants compared with their controls. HMA4 RNAi plants in cv.#1 background were compared with their WT controls (n = 3 replicates each), and HMA4 double-mutant plants in cv. #3 background were compared with their null-segregant controls (n = 4). The elements were measured in dry weight of lower leaves of plants grown under greenhouse conditions. The error bars depict the 0.95 confidence interval (CI) corrected according to Satterthwaite approximation. (b) Pictures of representative plants of each group (sticker size = 11.9 cm).
