INDEL variants identified in the regulatory regions of P. sojae genes. a Comparison of the sequence variation of regulatory regions for the Avr1b(+) and Avr1b(−). Variations in the Avr1b(+) and upstream sequences are marked in red, while that of Avr1b(−) and upstream sequences are marked in green. Avr1b-asRNA is marked in blue. R-D, the nucleotide sequence that encodes RXLR-DEER motif. b Frequency of the INDEL variants in the promoter region of P. sojae genes. The variants were called from the re-sequenced genomes of P. sojae strains P7064, P7074, and P7076, while the genome of strain P6497 was used as a reference. The 500 bp upstream sequences were regarded as the promoters for each gene. c The 9–10 bp INDEL variants are significantly enriched in the promoters of RXLR effector genes. One-sided Fisher’s exact test is used to access the significance
