Overexpression of GmWRKY172 reduced Cd accumulation in the shoots of soybean. (A, B) Phenotypes of soybean transgenic lines (OX4-7, OX6-2, OX9-5) and WT under normal or Cd-treated conditions. OX refers to GmWRKY172 overexpression. The chlorophyll contents of each plant were measured under normal (C) or Cd-treated (D) conditions (n = 30). Cd contents in the shoot (E) and root (F) of WT and transgenic lines were measured after 25 days of Cd treatment. (G) The root-to-shoot translocation factor of Cd (ratios of shoot/root Cd contents) in the WT and transgenic lines. Data are expressed as mean ± SD, n = 3 (E–G). Different letters indicate statistical significance determined by one-way analysis of variance and Duncan’s test (P ≤ 0.05).
