An auxin-driven polarized transport model for phyllotaxis
Recent studies show that plant organ positioning may be mediated by localized concentrations of the plant hormone auxin. Auxin patterning in the shoot apical meristem is in turn brought about by theExpand

Developmental Patterning by Mechanical Signals in Arabidopsis
A central question in developmental biology is whether and how mechanical forces serve as cues for cellular behavior and thereby regulate morphogenesis. We found that morphogenesis at the ArabidopsisExpand

Alignment between PIN1 Polarity and Microtubule Orientation in the Shoot Apical Meristem Reveals a Tight Coupling between Morphogenesis and Auxin Transport
Imaging and computational modeling of the Arabidopsis shoot meristem epidermis suggests that biomechanical signals coordinately regulate auxin efflux carrier distribution and microtubule patterningExpand

WUSCHEL protein movement mediates stem cell homeostasis in the Arabidopsis shoot apex.
WUSCHEL (WUS) is a homeodomain transcription factor produced in cells of the niche/organizing center (OC) of shoot apical meristems. WUS specifies stem cell fate and also restricts its own levels byExpand

Subcellular and supracellular mechanical stress prescribes cytoskeleton behavior in Arabidopsis cotyledon pavement cells
Although it is a central question in biology, how cell shape controls intracellular dynamics largely remains an open question. Here, we show that the shape of Arabidopsis pavement cells creates aExpand

Modeling Auxin Transport and Plant Development
The plant hormone auxin plays a critical role in plant development. Central to its function is its distribution in plant tissues, which is, in turn, largely shaped by intercellular polar transportExpand

Signaling from maize organ primordia via FASCIATED EAR3 regulates stem cell proliferation and yield traits
Shoot apical meristems are stem cell niches that balance proliferation with the incorporation of daughter cells into organ primordia. This balance is maintained by CLAVATA–WUSCHEL feedback signalingExpand

Plant stem cell maintenance involves direct transcriptional repression of differentiation program
In animal systems, master regulatory transcription factors (TFs) mediate stem cell maintenance through a direct transcriptional repression of differentiation promoting TFs. Whether similar mechanismsExpand

A Cell-Based Model for Quorum Sensing in Heterogeneous Bacterial Colonies
We use a cell-based model of growing bacterial microcolonies to investigate a quorum-sensing mechanism at a single cell level. Expand

Modeling the organization of the WUSCHEL expression domain in the shoot apical meristem
MOTIVATION The above-ground tissues of higher plants are generated from a small region of cells situated at the plant apex called the shoot apical meristem. Expand
