Identification of P. sojae Avr1b sRNAs. a The abundance distribution of Avr1b sRNA reads homologous to the ORF region. The sense sRNA reads (above the x-axis) are highlighted in red, and the antisense sRNA reads (below the x-axis) are highlighted in blue. b The position distribution of Avr1b reads homologous to the ORF region. The red arrows indicate Avr1b-siRNA molecules, and the blue arrow that spans two red reads is Avr1b-asRNA. The sRNA reads and reference gene sequences are all from P. sojae strain P6497. The position and length of sRNA reads are drawn in scale. c The size distribution of Avr1b-siRNAs
