Roots primed for better phosphate uptake Phosphate is a key resource plants, and remediating deficiency drives considerable fertilizer use. In low-phosphate conditions, roots make more root hairs, which makes them able to take up what little can be found. Wendrich et al. performed single-cell transcriptomics on the developing Arabidopsis queried resulting gene-expression atlas responses related vascular development. The authors found that signals regulating hair development began in inner...
Abstract Plant cells cannot rearrange their positions; therefore, sharp tissue boundaries must be accurately programmed. Movement of the cell fate regulator SHORT-ROOT from stele to ground has been associated with transferring positional information across boundaries. The zinc finger BIRD protein JACKDAW shown constrain movement a single layer, and other family proteins were postulated counteract JACKDAW's role in restricting action range. Here, we report that regulation requires additional...
In Arabidopsis, more than 1000 putative small signalling peptides have been predicted, but very few functionally characterized. One class of post-translationally modified is the C-TERMINALLY ENCODED PEPTIDE (CEP) family, which one member has shown to be involved in regulating root architecture. This work applied a bioinformatics approach identify members CEP family. It identified 10 additional and revealed that this family only emerged flowering plants was absent from extant primitive...
To create a three-dimensional structure, plants rely on oriented cell divisions and elongation. Oriented are specifically important in procambium cells of the root to establish different vascular types [1Dolan L. Janmaat K. Willemsen V. Linstead P. Poethig S. Roberts Scheres B.

Hormone-guided self-organization Auxin signals travel through pathways in developing or regenerating plant tissues to guide tissue formation. Hajný et al. now show that an auxin-regulated receptor turn regulates phosphorylation and thus subcellular localization of auxin transporter. Through this signaling pathway, builds the which it is transported, guiding development as goes. Science , issue p. 550
In arid and semi-arid climates, native plants have developed unique strategies to survive challenging conditions. These adaptations often rely on molecular pathways that shape plant architecture enhance their resilience. Date palms (Phoenix dactylifera) mangroves (Avicennia marina) endure extreme heat high salinity, yet the metabolic underlying this resilience remain underexplored. Here, we integrate tissue imaging with spatial metabolomics uncover shared distinct adaptive features in these...
Transcriptional networks are crucial to integrate various internal and external signals into optimal responses during plant growth development. In Arabidopsis thaliana, primary root vasculature patterning proliferation controlled by a network centred around the basic Helix-Loop-Helix transcription factor complex, formed TARGET OF MONOPTEROS 5 (TMO5) LONESOME HIGHWAY (LHW), which control cell division orientation modulating cytokinin response other downstream factors. Despite recent progress,...
Protein complex formation has been extensively studied using Förster resonance energy transfer (FRET) measured by Fluorescence Lifetime Imaging Microscopy (FLIM). However, implementing this technology to detect protein interactions in living multicellular organism at single-cell resolution and under native condition is still difficult achieve. Here we describe the optimization of labeling conditions FRET-FLIM plants. This study exemplifies procedure involving identification optimal position...
The roots of lycophytes branch through dichotomy or bifurcation, during which the root apex splits into two daughter roots. This is morphologically distinct from lateral (LR) branching in extant euphyllophytes, with LRs developing along axis at different distances apex. Although process bifurcation poorly understood, such knowledge can be important, because it may represent an evolutionarily ancient strategy that recruited to form new stem cells meristems. In this study, we examined...
In the Arabidopsis root, growth is sustained by meristem. Signalling from organiser cells, also termed quiescent centre (QC), essential for maintenance and replenishment of stem cells. Here, we highlight three publications founder concept cell niche in a pioneer unravelling regulatory modules governing specification maintenance, as well tissue patterning root meristem: Ben Scheres. His research has tremendously impacted plant field. We have selected Scheres legacy, which can be considered...
Abstract Growth regulation tailors plant development to its environment. A showcase is growth adaptation gravity, where shoots bend up and roots down. This paradox based on different responses the phytohormone auxin, which promotes cell expansion in shoots, while inhibiting it via a yet unknown cellular mechanism. Here, by combining microfluidics, live imaging, genetic engineering phospho-proteomics Arabidopsis thaliana , we reveal how auxin inhibits root growth. We show that activates two...
