Sublethal oxytetracycline and copper exposure alters rRNA gene copy number, expression, and intragenomic polymorphism in ciliates
{{output}}
Ribosomal RNA (rRNA) genes serve as foundational markers for microbial eukaryotic diversity assessment, yet their responses to environmental stressors remain underexplored. This study examined the effects of sublethal oxytetracycline and CuCl2 on phenotypic an... ...
