Phototropin-like LOV domains form a cysteinyl-flavin adduct in response to blue light but show considerable variation in output signal and the lifetime of the photo-adduct signaling state.

The discovery of LOV domains. Early genetic work on non-phototropic hypocotyl (nph) mutants in Arabidopsis thaliana 18 suggested that NPH1 (subsequently named PHOTOTROPIN 1 (PHOT1)) is the ...

Phototropin responds to blue light and regulates starch storage by activating or deactivating PMSK1, a protein that controls starch synthesis. Blue light reduces starch accumulation, while red ...

1) Phototropin receptors in the guard cells of stomata receives blue light; 2) Signal transmission by BLUS1, BHP and PP1 (proposed signaling components); 3) Activation of the plasma membrane ...
