Monoculture Breeds Poor Social Skills

摘要

Two studies from Jarosz et al. describe how [GAR~+], a protein-based epigenetic determinant found mainly in wild yeast strains, can be activated by microbial cross-kingdom communication. With the aid of genetically and ecologically diverse bacteria, yeast can override an ancient regulatory mechanism of glucose repression, promoting both microbial diversity and lifespan extension.
