Abstract

The opening of stomata in plants in response to blue light is driven by the plasma membrane H+-ATPase in guard cells. To evaluate the activation of the H+-ATPase in vivo, we can use H+-pumping by guard cells in response to blue light and fusicoccin. To do this, it is required to prepare a large amount of guard cell protoplasts and measure H+-pumping in the protoplasts. It is also necessary to determine the protein amount of H+-ATPase. In this protocol, we describe the procedures required for these preparations and measurements.

Background

The opening of stomata in response to blue light is driven by membrane hyperpolarization mediated through H+-pumping across the plasma membrane in guard cells (Assmann et al., 1985; Shimazaki et al., 1986), and is brought about by the plasma membrane H+-ATPase (Kinoshita and Shimazaki, 1999). The H+-ATPase generates an electrochemical gradient across the membrane, and provides the energy required for numerous secondary transports in plant cells. However, it is not easy to measure the activity of H+-ATPase in vivo. Taking advantage of the blue light-sensitive properties of guard cells, our method makes it possible to measure H+-pumping as an in vivo H+-ATPase activity using Arabidopsis guard cell protoplasts (Ueno et al., 2005). Together with H+-ATPase quantification by Western blot (Yamauchi et al., 2016), this method allows comparing H+-ATPase activity under different conditions or mutant backgrounds.
