TL;DR: Observations suggest that the Arabidopsis bHLH proteins have the potential to participate in an extensive set of combinatorial interactions, endowing them with the capacity to be involved in the regulation of a multiplicity of transcriptional programs.

TL;DR: The results suggest a role for PIF1 and other PIFs in transducing light signals to regulate PSY gene expression and carotenoid accumulation during daily cycles of light and dark in mature plants.

TL;DR: It is demonstrated that by directly targeting a common promoter cis-element (G-box), HY5 and PIFs form a dynamic activation-suppression transcriptional module responsive to light and temperature cues that provides a simple, direct mechanism through which environmental change can redirect transcriptional control of genes required for photosynthesis and photoprotection.

TL;DR: Basic helix-loop-helix (bHLH) transcription factors represent a family of proteins that contain a bHLH domain, a motif involved in binding DNA.

TL;DR: One of the seven disrupted genes displaying a significant mutant phenotype, the basic helix-loop-helix factor–encoding PHYTOCHROME-INTERACTING FACTOR3-LIKE1 gene, was found to be necessary for rapid light-induced expression of the photomorphogenesis- and circadian-related PSEUDO-RESPONSE REGULATOR9 gene, indicating a regulatory function in the early phy-induced transcriptional network.
