Expression of SOS2, SOS3, and SCABP8 in Arabidopsis.

(A) Expression of SOS2, SOS3, and SCABP8 in root, stem, leaf, flower, and silique determined by 30 cycles of RT-PCR with gene-specific primers. UBQ10 was a loading control.

(B) Expression of SOS2, SOS3, and SCABP8 in Arabidopsis seedlings in response to salt stress. Error bars represent sd (n = 3).

(C) to (F) SOS2 promoter-GUS expression in 10-d-old wild-type seedling (C), stem (D), root tip (E), and flower (F).

(G) to (I) SOS3 promoter-GUS expression in 10-d-old wild-type seedling (G), root tip (H), and root (I).

(J) to (O) SCABP8 promoter-GUS expression in 10-d-old wild-type seedling (J), root tip (K), root (L), leaf (M), stem (N), and flower (O).
