Supplementary Figure 2: Alignment of the SWEET13 promoter sequences from selected rice varieties.

Rice varieties having nucleotide variations in the PthXo2 EBE were identified using RiceVarMap v.2 (http://ricevarmap.ncpgr.cn/v2/). Two varieties were selected for each variation type as representative. Sequences of the first 400 bp of SWEET13 promoters of the selected varieties were extracted from the 3K database (http://snp-seek.irri.org/). Alignment was done using ClustalW in Geneious 11.1.5 (https://www.geneious.com). Nine variations were found in the PthXo2 EBE with frequencies ranging from 1.3% to 20.8%.
