Spatially structured yeast communities: Understanding structure formation and regulation with omics tools.

Area of Science:

• Microbiology and Cell Biology
• Mycology
• Biophysics

Background:

• Single-celled yeasts exhibit multicellular behaviors, forming structured populations such as colonies and biofilms.
• These populations can be single-species or mixed-species, involving cooperation with other microorganisms.
• Within these structures, yeast cells coordinate development, interact, and differentiate into specialized subpopulations.

Purpose of the Study:

• To summarize current knowledge on yeast multicellular structures and cell interactions.
• To highlight the adaptive strategies employed by yeast subpopulations.
• To identify future research directions for understanding yeast multicellularity.

Main Methods:

• Review of omics tools (genomics, transcriptomics, proteomics, metabolomics).
• Integration of specialized cell separation techniques.
• Application of in situ microscopy for observing cellular processes.
• Analysis of extracellular matrix contributions.

Main Results:

• Omics and microscopy have revealed key processes and cell interactions in yeast biofilms and colonies.
• Cellular differentiation allows adaptation to nutrient deficiency and protection from external factors.
• Extracellular matrix plays a role in protecting the overall population.

Conclusions:

• Current understanding of yeast multicellular structures is incomplete.
• Integrated multi-omics approaches are crucial for future research.
• Further emphasis on analyzing specialized, differentiated cell subpopulations is needed to unravel the complexity of yeast communities.
