The overview of the miRNAs changes in IR24 and IRBB5. (A) Principle component analysis of detected miRNAs in small RNA sequencing data. Green, blue and red box denotes samples at 0, 8 and 24 h after treatment with Xoo strain PXO86 in IR24, respectively. Similarly, green, blue and red dot denotes samples at 0, 8 and 24 h after treatment with Xoo strain PXO86 in IRBB5, respectively. The samples at different time point have three biological replicates. (B–D) Venn diagrams of up-regulated differentially expressed miRNAs (DE miRNAs) in IRBB5 and/or IR24 after PXO86 strain infection. (E–G) Venn diagrams of down-regulated DE miRNAs in IRBB5 and/or IR24 after PXO86 strain infection.
