Phytochrome signaling in the nucleus can activate expression of photosynthesis-associated genes in plastids. Here Yang et al. show that NCP is a dual-targeted protein that promotes phytochrome B localization to photobodies in the nucleus while ...

Synthetic Toll‐Like Receptors for Control of Innate Immunity With Far‐Red Light
Synthetic Toll‐like receptors (TLRs) are engineered by replacing their natural sensing regions with a far‐red‐light‐responsive module from a bacterial phytochrome. These synthetic receptors enable light‐controlled regulation of immune signaling in mammalian cells.

Light is both the main source of energy and a key environmental signal for plants. It regulates not only gene expression but also the tightly related processes of splicing and alternative splicing (AS).

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

Phytochrome-controlled level of growth substances in etiolated oat seedlings
Irradiation with red light of coleoptiles and leaves of etiolated oat seedlings, causing photoconversion of phytochrome mainly into Pfr, leads to the release of free auxins and free gibberellins from conjugated forms.

Immunocytochemical Localization of Phytochrome [PDF]
An immunocytochemical assay, which localizes phytochrome in situ , indicates that this plant chromoprotein is associated with both nuclei and plastids, in addition to the cytoplasm. In an etiolated oat shoot, phytochrome is most abundant just behind the apex of the coleoptile, where it is ...

Multi‐trait genome‐wide association mapping identifies a central hub regulator, COLD AND CATECHINS REGULATOR 1 (CCR1), and its excellent natural allele variation, coordinately enhancing cold tolerance and promoting catechins biosyntheis. CsCCR1 interacts with CsCBF1/3 and is transcriptionally activated by CsLUX and CsKUA1 to promote catechins ...

QM/MM Benchmarking of Cyanobacteriochrome Slr1393g3 Absorption Spectra
Cyanobacteriochromes are compact and spectrally diverse photoreceptor proteins that are promising candidates for biotechnological applications. Computational studies can contribute to an understanding at a molecular level of their wide spectral tuning ...

Germination of Ceratopteris richardii spores is initiated by light and terminates 3-4 days later with the emergence of a rhizoid. Early studies documented that the photoreceptor for initiating this response is phytochrome.

Phytochrome Immunoaffinity Purification [PDF]
We have developed a phytochrome immunoaffinity purification procedure that yields undegraded oat (Avena sativa L., cv. Garry) phytochrome of greater than 98% purity within 2 hours when starting with a brushite-purified preparation. Immunoaffinity-purified phytochrome, except for its greater purity, is indistinguishable from conventionally purified ...
