摘要：

How do plant cells accomplish a net uptake of Ca(2+) but keep the membrane potential under control? Consideration of the voltage dependence of the depolarization-activated calcium channel and hyperpolarization-activated calcium channel types, and two other major transporters in the plasma membrane, the H(+)-ATPase and I(K,out), suggests that one channel is well suited for both nutritive and signalling Ca(2+) uptake whereas the other could be limited to a signalling function.
