Xanthomonas sRNA

In molecular biology, Xanthomonas sRNA are small RNAs which have been identified in various species of the bacterium Xanthomonas.

Analysis of the plant pathogen Xanthomonas campestris pv. vesicatoria revealed expression of seven cis-encoded antisense RNAs (asX1-asX7) and 15 intergenic sRNAs (sX1 - sX15). Some of these sRNAs are only found in Xanthomonas, some are also expressed in other bacteria.[1] One of these sRNAs, sX12, contributes to virulence.[1]

Several sRNAs have also been identified in Xanthomonas campestris pathovar campestris.[2] One of these sRNAs, sRNA-Xcc1, may be involved in virulence.[3]

Computational analysis predicts 63 sRNAs in Xanthomonas oryzae pathovar oryzae, expression of 8 of these has been experimentally confirmed. Expression of three of these is Hfq-dependent.[4]
