Cell type boundaries organize plant development
In plants the dorsoventral boundary of leaves defines an axis of symmetry through the centre of the organ separating the top (dorsal) and bottom (ventral) tissues. Although the positioning of this boundary is critical for leaf morphogenesis, how the boundary is established and how it influences development remains unclear. Using live-imaging and perturbation experiments we show that leaf orient...
متن کاملCell-cell interactions during plant development.
The large body of information that has come from genome sequencing projects has demonstrated that plants and animals have many sequences in common, suggesting that they have either co-opted the same molecules for different purposes, or that they utilize similar mechanisms (Reuzeau and Pont-Lezica 1995; Clark 1996). One might expect many housekeeping tasks, such as regulation of the cell cycle, ...
متن کاملCentrosomes: Coiled-Coils Organize the Cell Center
The centrosome serves as a structural context for cytoplasmic organization. Recent studies on mutants of the nematode worm Caenorhabditis elegans have provided new insight into the framework to which microtubules and key regulators of centrosome behavior are anchored.
متن کاملEditorial: Plant Single Cell Type Systems Biology
The molecular responses of a plant to a stress and the molecular profiles of plant organs during their development and differentiation are the reflection of the contribution from different cell types composing the plant and the organs. Hence, a major limitation to understanding plant cellular and molecular responses in different cells is the multicellular complexity of the plant or organs used ...
متن کاملAsymmetric cell division in plant development.
Plant embryogenesis creates a seedling with a basic body plan. Post-embryonically the seedling elaborates with a lifelong ability to develop new tissues and organs. As a result asymmetric cell divisions serve essential roles during embryonic and postembryonic development to generate cell diversity. This review highlights selective cases of asymmetric division in the model plant Arabidopsis thal...
