Space and epigenetic inheritance determine inter-individual differences in siderophore gene expression in bacterial colonies

The paper tracks gene expression of siderophore synthesis genes in Pseudomonas aeruginosa colonies to identify sources and functional roles of cellular heterogeneity.

Enforced specialization fosters mutual cheating and not division of labour in the bacterium Pseudomonas aeruginosa

This study shows that enforced specialization in Pseudomonas aeruginosa leads to mutual cheating rather than division of labour under iron limitation.

From heterogeneity to homogeneity: coordination of siderophore gene expression among clonal cells of the bacterium Pseudomonas aeruginosa

The paper uses microscopy to study siderophore gene expression in Pseudomonas aeruginosa, finding initial heterogeneity that becomes homogenized with increasing cell density and a shift in siderophore usage.
