Light: an indicator of time and place
To grow and develop optimally, all organisms need to perceive and process information
from both their biotic and abiotic surroundings. A particularly important environmental cue is …

Molecular interaction between COP1 and HY5 defines a regulatory switch for light control of Arabidopsis development
LH Ang, S Chattopadhyay, N Wei, T Oyama, K Okada… - Molecular cell, 1998 - cell.com
Arabidopsis COP1 acts as a light-inactivable repressor of photomorphogenic development,
but its molecular mode of action remains unclear. Here, we show that COP1 negatively …

[HTML][HTML] PIF4, a phytochrome‐interacting bHLH factor, functions as a negative regulator of phytochrome B signaling in Arabidopsis
Plants sense and respond to red and far‐red light using the phytochrome (phy) family of
photoreceptors. However, the mechanism of light signal transduction is not well defined …

Direct targeting of light signals to a promoter element-bound transcription factor
Light signals perceived by the phytochrome family of sensory photoreceptors are transduced
to photoresponsive genes by an unknown mechanism. Here, we show that the basic helix …

Phytochromes control photomorphogenesis by differentially regulated, interacting signaling pathways in higher plants
▪ Abstract In this review the kinetic properties of both phytochrome A and B measured by in
vivo spectroscopy in Arabidopsis are described. Inactivation of phyA is mediated by …
