Plant phosphate homeostasis is regulated by an inositol pyrophosphate signaling molecule
Featured
Phosphorus is an essential building block for nucleic acids and membranes, forms an important energy currency of the cell and can act as a signaling molecule. Soil-living organisms take up phosphorus in the form of inorganic phosphate. How cells ‘measure’ … Continue reading
Pushing and pulling nucleosomes to control transcription initiation
Featured
Chromatin remodelers are protein machines that move or eject nucleosomes from the chromatin template to regulate gene expression. Kubik et al. show how two distinct classes of remodelers, which they call « pushers » and « pullers », interact genome-wide at promoter regions to … Continue reading
A common regulatory mechanism for plant photoreceptor signaling
Featured
Plants perceive light as an important environmental cue. They sense the UV-B part of the solar spectrum through the UVR8 photoreceptor that activates acclimatory responses associated with protection against this potentially damaging radiation. UVR8 enhances the stability of the HY5 … Continue reading
Michel Milinkovitch and Robbie Loewith receive an ERC Advanced Grant
Featured
The aim is to identify the drivers of Life’s morphological complexity and diversity, and to understand how TORC1 regulates, and is regulated by, vacuolar membrane tension. Continue reading
Seeds inherit memories from their mother
