Research Abstract

A number of ion transporters are involvedin uptake of nutrients from roots and gas exchange of stomata that are vital for higher plants to grow. Potassium channel is one of requisite channels that function on maintenance of ratio of potassium to sodium in salt-stressed plants. Environmental stresses induce oxidative stress to damage physiological function of plant cells. However, cellular mechanisms remain to be clarified. In this study, we examined effects of reactive oxygen species and aldehydes on plant potassium channels.
