Effects of 24-epibrassinolide and 28-homobrassinolide on iron plaque formation and the uptake of As and Cd by rice seedlings (Oryza sativa L.) in solution culture

The effects of 24-epibrassinolide (Br24) or 28-homobrassinolide (Br28) on the formation of iron plaque (IP) and the uptake of As and Cd by rice plant are poorly understood. Thus, the current work was performed to examine the impacts of Br24/Br28 (10−8 M) application on IP formation (50 mg Fe2＋ L−1 supply) and their interactions on As and Cd accumulation in rice seedlings exposed to As (III) (0.5 mg L−1) and/or Cd (0.5 mg L−1) stresses by a...
