From: Transcriptomic analysis of Verbena bonariensis roots in response to cadmium stress
Enrichment of Cd in plants. a Cd content in plant shoots. b Cd content in plant roots. c Total Cd content in Verbena bonariensis. A total of 50 mg/kg (T1), 100 mg/kg (T2), 200 mg/kg (T3), 300 mg/kg (T4), and 400 mg/kg (T5) were set up for 5 Cd concentrations. Standard error of the mean for three repetitions is represented by the error bars. The different letters above the bars indicate the significant difference at P < 0.05 among the different treatments.
