Fig. 2: bZIP49S, but not bZIP49L, negatively regulates salt tolerance in poplars.

a Phenotypes comparison of 60-day-old WT, bZIP49Lox, bZIP49Sox, and bzip49cr mutant plants under control and 100 mM NaCl conditions. b–e Measurement of chlorophyll content (b), Fv/Fm (c), K+ content (d), and Na+ content (e) under normal and salt stress conditions. f–i Net K+ (f, h) and Na+ (g, i) fluxes in the root meristem and elongation zone measured using NMT. Box plots show the median (center line), the 25th and 75th percentiles (box bounds), and whiskers extending to 1.5 times the interquartile range (IQR). Dots represent outliers beyond the whiskers. n = 12 biological replicates. Line and bar charts show time course flux data and mean ± SE values (n = 3 biological replicates). Different letters indicate significant differences (P < 0.05, two-way ANOVA; P values are shown in Source Data file). Source data are provided as a Source Data file.
