The Guard cells control the openings of the stomata in plants. Their functioning is goverened by the availability of water in the plant's environment. When water is plentiful, the guard cells swell and move away from the opening. This incre...

This extensive single-cell-type proteome includes 336 proteins not previously represented in transcriptome analyses of guard cells and 52 proteins classified as signaling proteins by Gene Ontology analysis, of which only two have been previously assessed in the context of guard cell function.

ROP2 is a negative factor activated by light, with ROP2 activity leading to attenuation of the light response of guard cells. Therefore, this work describes an additional mode of regulation of stomatal aperture in the light.

The Arabidopsis genome encodes seven VSRs. In this work, the spatio-temporal expression of one of the members of this gene family, AtVSR3, was determined by RT-PCR and promoter::reporter gene fusions. AtVSR3 was expressed specifically in guard cells.
