Abstract
Pretreatment with pertussis toxin or microinjection of guanosine-5′-(3-thiotriphosphate) (GTP-γ-S) into guard cells in peeled epidermis of Commelina commuais L. promoted stomatal opening under subsaturating white light. Guanosine-5′-(2-thiodiphosphate) (GDP-β-S) and adenosine-5′-(3-thiotriphosphate) (ATP-γ-S) did not change stomatal aperture under identical conditions. These results indicate that G proteins may be involved in the regulation of stomatal opening.
