Additional file 2: Figure S2. of A comparative gene analysis with rice identified orthologous group II HKT genes and their association with Na+ concentration in bread wheat

DNA Sequence alignment of the OsHKT2;1-OsHKT2;4 intergenic region (A) and TaHKT2;1-TaHKT2;2 intergenic region on 7AL, 7BL and 7DL (B). The complete sequence of PIF/Harbinger type MITE is highlighted in purple, remnants of a CACTA type transposon “DTC_Isidor” in blue and individual motifs of tandem duplications are in red, yellow, green and dark blue. Boxed sequences represent salt activated cis-acting regulatory elements and other regulatory motifs in the OsHKT2;4 and TaHKT2;2 promoter regions. (RTF 545 kb)
