Claim 1biological rolesupports2005Source 1DOI PubMed

Arabidopsis cryptochromes CRY1 and CRY2 have a role in the regulation of stomatal opening.

Quoted textsource-backed

Here, we report a previously uncharacterized role for Arabidopsis CRY and COP1 in the regulation of stomatal opening.

Claim 2genetic interactionsupports2005Source 1DOI PubMed

PHOT1 and PHOT2 are not solely responsible for blue light-induced stomatal opening because the phot1 phot2 double mutant still responds to blue light, whereas the cry1 cry2 phot1 phot2 quadruple mutant hardly responds.

Quoted textsource-backed

stomata of the phot1 phot2 double mutant responded to blue light, but those of the cry1 cry2 phot1 phot2 quadruple mutant hardly responded

Claim 3genetic perturbation phenotypesupports2005Source 1DOI PubMed

The cry1 cry2 double mutant shows reduced blue light response in stomata.

Quoted textsource-backed

Stomata of the cry1 cry2 double mutant showed reduced blue light response

Claim 4overexpression phenotypesupports2005Source 1DOI PubMed

CRY1-overexpressing plants show a hypersensitive stomatal response to blue light.

Quoted textsource-backed

those of the CRY1-overexpressing plants showed hypersensitive response to blue light

Claim 5pathway ordersupports2005Source 1DOI PubMed

COP1 likely acts downstream of CRY and PHOT signaling pathways in stomatal opening regulation.

Quoted textsource-backed

COP1 is a repressor of stomatal opening and likely acts downstream of CRY and PHOT signaling pathways

Claim 6pathway relationshipsupports2005Source 1DOI PubMed

CRY functions additively with PHOT in mediating blue light-induced stomatal opening.

Quoted textsource-backed

These results indicate that CRY functions additively with PHOT in mediating blue light-induced stomatal opening
