The paper investigates the genomic diversity and metabolic traits of Fructilactobacillus isolates from honeypot ant crop microbiomes and identifies factors contributing to their dominance.

This study shows that uni-obligate endosymbionts have lost metabolic genes present in free-living bacteria and bi-obligate endosymbionts, suggesting a stochastic ratchet model for endosymbiotic fate.

This study identifies mitochondrial efficiency as the key factor determining the Crabtree effect in yeasts by comparing Pichia kluyveri and Saccharomyces cerevisiae.

This study uses a resource allocation model to compare metabolic strategies in Saccharomyces cerevisiae under different conditions, finding increased energy costs in respiratory-deficient strains.

The paper develops a computational model of fission yeast metabolism to explore resource allocation and metabolic strategies under different glucose conditions.

The paper shows that Saccharomyces cerevisiae maintains excess glycolytic enzyme capacity under glucose-limited conditions as an adaptation to environmental nutrient fluctuations.

The paper develops a whole-cell metabolic model for yeast to predict compartment-specific proteome constraints that explain metabolic strategies under different growth conditions.
