Summary
This study introduces DigR, a novel, open-source software for simulating plant root systems. DigR models root architecture at the organ level, integrating environmental factors for accurate plant characterization and versatile root system simulations.
Area of Science:
- Plant Biology
- Computational Biology
- Ecology
Background:
- Existing mathematical models for root systems often lack organ-level detail and integration of environmental influences.
- Root architecture modeling has seldom incorporated environmental factors into a whole plant characterization.
Purpose of the Study:
- To develop a generic, organ-level model for root system architecture that integrates environmental influences.
- To create a user-friendly, open-source software simulator (DigR) for plant root system modeling.
Main Methods:
- A multidisciplinary approach combining field observations, architectural analysis, and mathematical modeling.
- Development of the DigR simulator within the Xplo environment, featuring a user interface for parameter input and 3-D visualization.
- Utilizing a quasi-parallel computing algorithm for simulation and enabling integration with other platforms.
Main Results:
- DigR is based on root system architectural analysis, root type classification, and 23 flexible root type parameters.
- The model accurately simulates growth, branching, mortality, and reiteration processes for diverse root architectures, including tap-root, fasciculate, and tuberous systems.
- Demonstrated versatility in simulating plastic responses to environmental constraints through plugin examples.
Conclusions:
- DigR provides a botanically accurate and generic model for root system architecture, directly linked to field measurements.
- The open-source DigR simulator offers accuracy and versatility for simulating complex root systems in both annual and perennial plants.
- The software is freely available and integrates environmental factors for comprehensive plant characterization.

The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

Archaea, one of the three domains of life, exhibit remarkable diversity and adaptability, thriving in both extreme and moderate environments. Historically, most identified archaea have been classified into two major phyla: Euryarchaeota and Crenarchaeota. However, recent molecular studies have expanded this classification to include three additional phyla: Thaumarchaeota, Nanoarchaeota, and Korarchaeota, each exhibiting unique characteristics and ecological roles.Thaumarchaeota: Mesophiles...

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
