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)

本数据集包含OsHKT2;1与OsHKT2;4基因间区的DNA序列比对（图A），以及位于7AL、7BL与7DL染色体臂上的TaHKT2;1与TaHKT2;2基因间区的DNA序列比对（图B）。其中，PIF/Harbinger类微型反向重复转座元件（MITE）的完整序列以紫色高亮显示，CACTA类转座子“DTC_Isidor”的残迹以蓝色标注，串联重复的各基序分别以红色、黄色、绿色及深蓝色标注。OsHKT2;4与TaHKT2;2启动子区域中，带框序列代表盐激活型顺式作用调控元件及其他调控基序。（RTF 545 kb）
