Complementing model species with model clades

Area of Science:

• Plant evolutionary biology
• Genomics and phylogenomics
• Model organism research

Background:

• Model species are crucial for plant science advancements.
• Phylogenetic resolution of land plants is continually improving.
• Integrating model species utility with broader taxonomic groups offers new research avenues.

Purpose of the Study:

• To promote the use of Arabidopsis thaliana as a model species for the Brassicales order.
• To establish a 'model clade' by connecting Arabidopsis genetic resources to other Brassicales species.
• To explore trait evolution and diversification across the Brassicales using genomics and phylogenomics.

Main Methods:

• Utilizing genomics and phylogenomics to analyze trait evolution.
• Connecting genetic and functional resources of Arabidopsis thaliana to related species.
• Comparative analysis of Brassicales-wide traits within the context of Arabidopsis and Brassicaceae.

Main Results:

• Demonstrates the potential to extend the scope of model species research across larger taxonomic groups.
• Highlights the utility of genomics and phylogenomics in bridging evolutionary studies with model organism resources.
• Provides a framework for understanding trait diversification within the Brassicales order.

Conclusions:

• Establishing a 'model clade' for Brassicales enhances research capabilities beyond a single model species.
• Genomic and phylogenomic approaches are key to understanding evolution in diverse plant groups.
• Recommends building global networks to support future research in the Brassicales order.
