Large-scale duplication events underpin population-level flexibility in tRNA gene copy number in Pseudomonas fluorescens SBW25

The paper shows that Pseudomonas fluorescens SBW25 can rapidly generate tRNA gene set diversity through unstable large-scale duplications, which can preserve or alter tRNA gene copy numbers depending on selection pressure.
