Using two representative strains from populations of S. baltica, our results indicate transcriptional divergence can occur faster than changes in gene content, and highlight the importance of transcriptional characterization for studying bacterial speciation. Compared to investigations on genome content diversification among closely related microorganisms, the transcriptomic diversification and the ecological implications have been assessed in relatively few studies. Parkinson et al. investigated transcriptional differences among coral-associated dinoflagellate strains within one Symbiodinium clade, and revealed species-specific expression differences consistently enriched in photosynthesis-related genes, whereas strain-specific expression differences may contribute to host-symbiont genotype parings (Parkinson et al., 2016). Carreto et al. compared transcriptional profiles of environmental, clinical and laboratorial Saccharomyces cerevisiae strains during fermentation, and revealed that gene expression patterns of winemaking strains were associated with better adaptation under stress-imposing and nutrient-, especially nitrogen-limiting conditions (Carreto et al., 2011). Through investigating gene expression of two Burkholderia cenocepacia strains, one isolated as a soil dweller from an agricultural field and the other as a pathogen from a cystic fibrosis (CF) patient, in conditions mimicking those two environments, Yoder-Himes et al. showed the soil strain exhibited a…
