The perception of light signals by the phytochrome family of photoreceptors has a crucial
influence on almost all aspects of growth and development throughout a plant's life cycle …

Phytochromes are bilin-binding photosensory receptors which control development over a
broad range of environmental conditions and throughout the whole plant life cycle. Light …

Phytochrome B (phyB) is a plant photoreceptor that forms a membraneless organelle called
a photobody. However, its constituents are not fully known. Here, we isolated phyB …

Chloroplasts are best known for their role in photosynthesis, but they also allow nitrogen and
sulphur assimilation, amino acid, fatty acid, nucleotide and hormone synthesis. How …

Chloroplasts evolved from an ancient cyanobacterial endosymbiont more than 1.5 billion
years ago. During subsequent coevolution with the nuclear genome, the chloroplast …

The developmental program by which plants respond is tightly controlled by a complex
cascade in which photoreceptors perceive and transduce the light signals that drive …

Chloroplasts produce singlet oxygen (1O2), which causes changes in nuclear gene
expression through plastid-to-nucleus retrograde signaling to increase plant fitness …

Warm temperature is postulated to induce plant thermomorphogenesis through a signaling
mechanism similar to shade, as both destabilize the active form of the photoreceptor and …

Communication between cellular compartments is vital for development and environmental
adaptation. Signals emanating from organelles, so-called retrograde signals, coordinate …

Light initiates chloroplast biogenesis in Arabidopsis by eliminating PHYTOCHROME-
INTERACTING transcription FACTORs (PIFs), which in turn de-represses nuclear …
