Novel model organisms and proteomics for a better biological understanding

Area of Science:

• Evolutionary biology
• Systems biology
• Proteomics

Background:

• Traditional model organisms like Escherichia coli and Saccharomyces cerevisiae are valuable but limited for complex research.
• Advancements in multi-omics technologies allow comprehensive molecular event capture across diverse organisms.
• Unanswered biological questions necessitate more complex systems, including biodiversity and host-microbe interactions.

Purpose of the Study:

• To re-evaluate the concept of model organisms in the context of modern multi-omics technologies.
• To highlight the emergence and importance of holobionts for studying integrated biological systems.
• To explore the potential of comparative evolutionary proteomics in understanding organismal diversity and adaptation.

Main Methods:

• Review and synthesis of current multi-omics technologies and their impact on biological research.
• Conceptual framework development for holobionts as integrated research systems.
• Application of comparative evolutionary proteomics for cross-species protein diversity analysis.

Main Results:

• Multi-omics technologies enable a holistic view of molecular events, challenging the limitations of traditional model organisms.
• Holobionts offer a unified approach to study host-microorganism interactions and ecosystem dynamics.
• Comparative evolutionary proteomics provides insights into protein diversity across Bacteria, Archaea, and Eukarya.

Conclusions:

• The concept of model organisms needs re-evaluation; integrated systems like holobionts are essential for complex biological questions.
• Comparative evolutionary proteomics is a powerful tool for identifying key molecular players under environmental stress.
• This approach aids in developing sustainable solutions for challenges like pollution, pathogens, and climate change.
