Fig. 1

a Distribution of SNPs and DEGs between NIL_Rf4 and NIL_rf4. From inner circle to the outer circle, the first and the second circles indicate the distribution of SNPs within exons and genome, respectively. In the third circle, the green dots represent up-regulated transcripts in NIL_Rf4, while the red dots represent down-regulated transcripts. b SNP index graphs of the NIL_Rf4 (yellow lines) and NIL_rf4 (black lines)
