Due to an unfortunate mistake, an incorrect version of Fig. 4 has been used in the above mentioned publication. The internal control of U6 in Fig. 4b was accidentally duplicated from Fig. 4a. The adjusted Fig. 4 with the correct U6 control is published below and should be treated as definitive by the reader.

Small RNA Northern blot verification of some of the differentially expressed miRNAs detected by deep sequencing from the three bacterial pathogen infections and the mock controls at a 6-hpi and b 14-hpi. Similar results were obtained from two biological duplicates. U6 RNA was used as a control for measuring the relative amount of the bands (shown below each panel). Imagequant software version 2.1 was used for relative amount quantification (GE Healthcare Life Sciences)
