Characterization of gene structure around GmST1 genomic region. (A) Schematic summary of different gene prediction models around GmST1 genomic region. Black bars represent exons, gray bars are untranslated regions (5′-UTR and 3′-UTR), and lines represent introns in their expected gene models. Primer positions (P1 through P6) are indicated in response to different gene prediction models. (B) GmST1 and Gm0063×00341 expression pattern analysis in soybean leaf tissues. RT-PCR was conducted using primer pairs corresponding to GmST1 and Gm0063×00341, respectively. Total RNA was isolated from the salt treated and untreated leaves of soybean varieties WF-7 and Union. (C) Prediction and experimental RT-PCR products around GmST1 genomic region.
