(a–f) Growth-related features of wild-type (WT) and d10 and d17 mutant plants exposed to different concentrations of sodium arsenate (Na₂AsO₄; 0, 125 and 250 μM As^V). Shoot phenotypes were recorded on day 3 (a) and day 5 (b) of As^V treatments. Shoot height (c), shoot dry weight (d), and the levels of total chlorophylls (e) and carotenoids (f) were assessed on day 5 of As^V treatments. (g) Relative expression of D10 and D17 genes was examined in the shoots of WT on day 3 of As^V treatments. Represented numerical data are the means with standard errors (n = 4 biological repeats). Significant differences (p < 0.05) among the treatments are denoted by distinct alphabetical letters according to a least significant difference test. Student’s t-test (** p < 0.01) was conducted to identify significant variations among 0, 125 and 250 μM As^V treatments (g). Chls, chlorophylls; DW, dry weight; FW, fresh weight.
