Pathways and Characteristics of Lead Uptake and Transportation in Rhus chinensis Mill

Rhus chinensis Mill is a potential plant for phytoremediation of Pb and able to uptake copious amount Pb. However, little known about the pathways properties in this plant. Here, controlled experiments were used assess translocation R. chinensis. The whole time-kinetics divided into two stages: rapid slower accumulation, processes fitted with linear model. concentration-dependent kinetics characterized by modified Michaelis–Menten equation. Km Vmax value influx roots 19.44 14.83, respectively. Transpiration inhibitors had no significant effect on concentration root shoot. Low temperatures (4 °C) metabolic (carbonyl cyanide m-chlorophenylhydrazone 2,4-dinitrophenol) significantly reduced leaves plants. Furthermore, addition calcium ion channel protein synthesis These results show that both active passive exist In addition, plants was related channels.
