Expression pattern of the full-size BvNHX1 promoter. a Scheme of full-size BvNHX1 promoter structure. Upstream promoter sequence, 5′ UTR, and intron are marked in gray, black and white, respectively. Nucleotides are numbered in according to the translation start ATG start sequence. b–i Arabidopsis plants expressing the 2,487 bp BvNHX1::GUS constructs were grown under non-stressed conditions. Histochemical staining of GUS was performed as described in “Materials and methods”. b Shoot of soil grown plant. c Section of a mature leaf. d Close-up of the edge of the leaf shown in (c). e Primary roots. f Root hairs. g Emerging lateral root. h Flower. i Silique
