Definition
Proper noun A small, invasive, self-pollinating weed plant species with small white flowers. It is extensively used as a model organism in plant biology and genetics research, notable for being the first higher plant to have its complete genome sequence fully mapped and described.
Usage
Arabidopsis thaliana is used as the scientific name for a specific plant species. It is typically referred to in academic, scientific, and research contexts. - In formal writing, the genus name (Arabidopsis) is capitalized and the species name (thaliana) is in lowercase, and the entire name is often italicized. - In common scientific parlance, it is frequently abbreviated as Arabidopsis or simply called "thale cress."
Examples
- In a research paper: " was used to study the gene's function due to its short life cycle and fully sequenced genome."
- In a lecture: "Many fundamental discoveries in plant physiology were first made in the model organism ."
- In a news article: "Scientists using have identified a key protein involved in drought resistance."
Advanced Usage
- As a genetic model: The phrase is used to signify a standard experimental system. Example: "The pathway was characterized in before being studied in crops."
- In phylogenetic studies: Used to denote a representative of the Brassicaceae family. Example: "The evolutionary history of this gene family was traced using as a reference."
