Claim 2binding interactionsupports2016Source 1DOIPubMed

PCH1 binds phytochrome B in a red light-dependent manner.

Quoted textsource-backed
PCH1 peaks at dusk, binds phytochrome B (phyB) in a red light-dependent manner
Claim 3colocalizationsupports2016Source 1DOIPubMed

PCH1 co-localizes with phytochrome B into photobodies.

and co-localizes with phyB into photobodies.
Claim 4integrative functionsupports2016Source 1DOIPubMed

PCH1 regulates photoperiod-responsive growth by integrating the clock with light perception pathways through modulating daily phyB signaling.

Quoted textsource-backed
Thus, PCH1 is a new factor that regulates photoperiod-responsive growth by integrating the clock with light perception pathways through modulating daily phyB-signaling.
Claim 5mechanistic rolesupports2016Source 1DOIPubMed

PCH1 is necessary and sufficient to promote the biogenesis of large photobodies and maintain an active phyB pool after light exposure.
