Measurement of proton-linked transport activities in pyranine loaded chloroplast inner envelope vesicles.

abstract：:High temperature promotes guard cell expansion, which opens stomatal pores to facilitate leaf cooling. How the high-temperature signal is perceived and transmitted to regulate stomatal aperture is, however, unknown. Here, we used a reverse-genetics approach to understand high temperature-mediated stomatal opening in A...
