Figure 7.

Thiol fluxes are altered in ts-pgdh1 lines. SO₄²⁻ (A), Cysteine (Cys; B), and glutathione incorporation (C) in AP and roots of two ts-pgdh1 lines (ts-pgdh1.1 and ts-pgdh1.2) as compared with control wild type transformed with the EV. The total contents were determined by flux analysis using ³⁵S as a tracer. Plants were incubated for 4 h in medium supplemented with ³⁵SO₄²⁻, and the distribution of ³⁵S was analyzed. Data presented are means ± se (n = 5). *Significantly different to control EV (P < 0.05, Student’s t test).
