Cell polarity is an ancient organizing principle across kingdoms. As in animal epithelial cells, plant cells asymmetrically distribute proteins to establish functionally distinct membrane domains. In ...

Multicellular development is tightly coupled to the polarization of individual cells, which partitions polar proteins along the cell cortex and can control asymmetric cell division, anisotropic growth...

BR synergizes with cytokinin to enhance WUS activity for SAM maintenance and prevents SAM arrest by repressing FRUITFUL.

Small molecules produced by TIR (Toll-interleukin-1 receptor) domains are essential for plant immune signaling. A central TIR-derived signal is 2'cADPR, a cyclic ADP-ribose (ADPR) molecule that is gen...

Cold Spring Harbor Laboratory Meetings & Courses -- a private, non-profit institution with research programs in cancer, neuroscience, plant biology, genomics, bioinformatics.

The plant cell wall regulates development through spatiotemporal modulation of its chemical and mechanical properties. Pectin methylesterification is recognized as a rheological switch controlling wal...

Brassinosteroids are essential plant hormones that play a central role in regulating growth, development, and stress responses. Their impact on plant architecture and productivity makes them attractiv...

A positional and developmentally regulated cell cycle duration gradient exists in the root meristem whereby the G1 phase is very long close to the stem cell niche. This relies on the interplay of PLET...

For sexually reproducing organisms to pass on their genetic information, progeny must successfully establish. Various life history strategies have evolved, using either dispersal of large numbers of p...

During morphogenesis of multicellular organs, cells acquire distinct identities that meet specific functional requirements. Epidermal identity is widely considered essential for plant morphogenesis du...

A cross-species single-cell atlas highlights a core subset of cell-type foundational genes associated with major vascular plant cell types, enabling the identification of hidden cell types and the dev...

Cryo-focused ion beam scanning electron microscopy (cryo-FIBSEM) has become essential for preparing electron-transparent lamellae from cryo-plunged and high-pressure frozen specimens. However, targeti...

When building an organ, adjacent cells coordinate to form topologically stable junctions by integrating mechanosensitive signaling pathways. Positioni…

A grafting-based approach combined with modeling uncovers how root system architecture is shaped by the distinct yet essential contributions of the shoot and root through brassinosteroid signaling.

Membrane contact sites (MCSs) serve a critical role in intracellular communication, particularly between organelle membranes, enabling direct molecular transfer. Less clear is the role MCSs play in…

Fougère, Grison et al. show that the ER–Golgi intermediate compartment (ERGIC) in plants is a tubulo-vesicular network marked by MEMBRIN proteins that is largely Golgi-independent. The plant ERGIC mat...

Plant intercellular communication is regulated via tubular ER-PM membrane contact through PI4P and MCTP protein tethers.

Plants grow complex root systems to extract unevenly distributed resources from soils. Spatial differences in soil moisture are perceived by root tips, leading to the patterning of new root branches t...

Di Fino et al. analyzed the biomechanical properties of the cell wall in the Arabidopsis root and found that xylem pole pericyclic cell walls are more flexible than outer cell walls. This flexibility ...

Nature Communications - Auxin is a universal regulator of plant growth and development. The authors report the origin and evolutionary history of the key DNA-binding transcription factors mediating...

Brassinosteroid (BR) phytohormones operate at both the cellular and organ levels, and impart distinct transcriptional responses in different cell types and developmental zones, with distinct effects o...

Oriented cell divisions are crucial for determining the overall morphology and size of plants, but what controls the onset and duration of this process remains largely unknown. Here, we identified a s...
