摘要： The expression of non-coding RNAs (ncRNAs) has been observed in a variety of bacteria. However, the function of ncRNAs and their regulatory targets are largely unknown, and few ncRNAs are found to be associated with bacterial virulence. The bacterial brown stripe pathogen Acidovorax oryzae (Ao) RS-1 shows a high level of condition-dependent differential expression of ncRNA, which we identified in a genome wide screen. We experimentally validated 66 differentially expressed ncRNAs using an integrative analysis of conservative genome sequences and transcriptomic data during in vivo interaction of the bacterial pathogen with the rice plant. To test the relevance of the differentially expressed ncRNAs, we chose four with different positions within the genome, and with different secondary structures and promoter activities. The results show that the overexpression of the four ncRNAs caused a significant change in virulence-related phenotypes, resistance to various environmental stresses, expression of secretion systems and effector proteins, while changing the expression of ncRNA putative target genes. We conclude that these ncRNAs are examples for the inherent regulatory roles for many of the observed ncRNAs in response to changing conditions such as host interaction or environmental adaption.
