Linked Claims

Claim 1binding interactionsupports2003Source 1DOIPubMed

A 14-3-3 protein binds to Vicia faba phototropins upon phosphorylation.

Quoted textsource-backed
We found that a 14-3-3 protein was bound to Vfphots upon phosphorylation
Claim 2functional rolesupports2003Source 1DOIPubMed

Vicia faba phototropins act as blue-light receptors in guard cells.

Quoted textsource-backed
We conclude that Vfphots act as BL receptors in guard cells
Claim 3generalitysupports2003Source 1DOIPubMed

Blue-light-induced binding of a 14-3-3 protein to phototropin also occurs in etiolated seedlings and leaves, suggesting it is common to phototropin-mediated responses.

Quoted textsource-backed
The binding of a 14-3-3 protein to Vfphot was found in etiolated seedlings and leaves in response to BL, suggesting that this event was common to phototropin-mediated responses.
Claim 4mechanistic modelsupports2003Source 1DOIPubMed

Phosphorylation of a serine residue between LOV1 and LOV2 followed by 14-3-3 protein binding is likely to be a key step in the blue-light response in stomata.

Quoted textsource-backed
phosphorylation of a Ser residue between LOV1 and LOV2 and subsequent 14-3-3 protein binding are likely to be key steps of BL response in stomata
Claim 5molecular eventsupports2003Source 1DOIPubMed

Blue light induces phosphorylation of Vicia faba phototropins in guard cell protoplasts.

Quoted textsource-backed
Using guard cell protoplasts, we showed that broad bean (Vicia faba) phototropins (Vfphots) were phosphorylated by BL
Claim 6site mappingsupports2003Source 1DOIPubMed

The phosphorylation sites identified for Vfphot1a and Vfphot1b are Ser-358 and Ser-344, respectively, located between LOV1 and LOV2.

Quoted textsource-backed
phosphorylation sites were determined to be Ser-358 for Vfphot1a and Ser-344 for Vfphot1b, which are localized between LOV1 and LOV2
Claim 7temporal ordersupports2003Source 1DOIPubMed

Phosphorylation of Vicia faba phototropins reaches its maximum earlier than phosphorylation of the H+-ATPase.

Quoted textsource-backed
this phosphorylation of Vfphots reached to the maximum level earlier than that of the H+-ATPase
