Host infection selects for sRNA variants that drive bacterial social cheating

2025-12-21

Abstract excerpt

Single-nucleotide mutations in regulatory small RNAs (sRNAs) represent a largely unexplored route to social cheating during bacterial infection. Here we show that arcZ , encoding a conserved Hfq-dependent sRNA in the plant pathogen Dickeya solani , undergoes recurrent single-nucleotide mutations during potato tuber infection. Five distinct arcZ alleles define a graded series of ArcZ functional impairment in whi...
