Elevated ascorbate protects Arabidopsis from stress-induced morphogenetic responses caused by pyrene (PYR). (a) Reduction of the growth of the aerial tissue in WT, while high-AsA lines grow normal in the presence of PYR. PYR inhibits leaf expansion (b) and reduces the amount of root hairs (c) in WT, but does not affect high-AsA lines (GLOase data shown here). Seeds were germinated on MS medium and then transferred to MS plus PYR for 14 d. Images were collected 3 wk after sowing. (d) Effect of PYR on root length of the wild type and transgenic lines grown on agar plates plus PYR for 19 d. Data are means ± SD of 50 biological replicates. (e) Total AsA content of seedlings grown under PYR stress. Data are means ± SD of 5 biological replicates (each replicate containing five seedlings). The proportion of reduced ascorbate was 95% or higher of the total AsA. *Indicates significant differences between WT and high-AsA lines (t-test, P=0.05).
