Morphogenesis

Morphogenesis

Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Gastrulation

Gastrulation

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Area of Science:

Developmental biology
Mathematical modeling
Synthetic biology

Background:

Periodic spatial patterning is crucial for forming repetitive structures like digits and teeth during multicellular development.
Turing patterning models, traditionally requiring at least two morphogens, form the basis for understanding these systems.

Purpose of the Study:

To investigate if a single diffusible morphogen can generate stable, long-range spatial patterns.
To explore mechanisms for enhancing pattern robustness against noise.

Main Methods:

Mathematical modeling was employed to simulate pattern formation dynamics.
Analysis of a single-morphogen system with and without intracellular feedback or on a growing cell lattice.

Main Results:

A single diffusible morphogen is sufficient to generate long-range, spatially periodic patterns.
These patterns propagate from perturbations and remain stable after the initial stimulus is removed.
Bistable intracellular feedback or a growing cell lattice enhances pattern robustness to noise.

Conclusions:

Spatial pattern formation can be achieved with a single morphogen, simplifying existing models.
This single-morphogen system provides a foundation for engineering pattern formation in synthetic developmental biology.
