In epithelia, tricellular vertices are emerging as important sites for the regulation of epithelial integrity and function. Compared to bicellular contacts, however, much less is known. particular, resident proteins at were identified only occluding junctions, with none known adherens junctions (AJs). a previous study, we discovered that in Drosophila embryos, adhesion molecule Sidekick (Sdk), well-known invertebrates vertebrates its role visual system, localises level AJs.

Using the plant model Arabidopsis, relationship between day length, size of shoot apical meristem, and robustness phyllotactic patterns were analysed. First, it was found that reducing length leads to an increased meristem number alterations in final positions organs along stem. Most defects could be related altered tempo organ emergence, while not affecting spatial initiations at meristem. A correlation also phyllotaxis two accessions (Col-0 WS-4) a mutant (clasp-1), independent growth...
Cell intercalation is a key cell behaviour of morphogenesis and wound healing, where local neighbour exchanges can cause dramatic tissue deformations such as body axis extension. Substantial experimental work has identified the molecular players facilitating intercalation, but there remains lack consensus understanding their physical roles. Existing biophysical models that represent cell-cell contacts with single edges cannot study exchange continuous process, neighbouring cortices must...
Organs form with remarkably consistent sizes and shapes during development, whereas a high variability in growth is observed at the cell level. Given this contrast, it unclear how such consistency organ scale can emerge from cellular behavior. Here, we examine an intermediate scale, of clones cells Arabidopsis sepals. Each clone consists progeny single progenitor cell. At early stages, find that derived small grow faster than those large This results reduction size variability, phenomenon...

Abstract Organs form with remarkably consistent sizes and shapes during development, whereas a high variability in size growth is observed at cell level. Given this contrast, it unclear how such consistency organ scale can emerge from cellular behavior. We examine the of lineages, or groups cells that are progeny single mother cell. At early stages lineage, we find initially smaller lineages grow faster than larger ones reducing lineage size, phenomenon refer to as uniformization. In...
ABSTRACT Cell intercalation is a key cell behaviour of morphogenesis and wound healing, where local neighbour exchanges can cause dramatic tissue deformations such as body axis extension. Here, we develop mechanical model to understand active behaviours in the context an epithelial tissue. Extending existing descriptions, vertex models, junctional actomyosin cortex every modelled continuum morphoelastic rod, explicitly representing cortices facing each other at bicellular junctions.
