Carbon nanoparticles enhance potassium uptake via upregulating potassium channel expression and imitating biological ion channels in BY-2 cells.

ABSTRACT:

Background

Carbon nanoparticles (CNPs) have been reported to boost plant growth, while the mechanism that CNPs enhanced potassium uptake for plant growth has not been reported so far.

Results

In this study, the function that CNPs promoted potassium uptake in BY-2 cells was established and the potassium accumulated in cells had a significant correlation with the fresh biomass of BY-2 cells. The K⁺ accumulation in cells increased with the increasing concentration of CNPs. The K⁺ influx reached high level after treatment with CNPs and was significantly higher than that of the control group and the negative group treated with K⁺ channels blocker, tetraethylammonium chloride (TEA⁺). The K⁺ accumulation was not reduced in the
