Tissue-Specific Expression of CEK4 by Histochemical GUS Staining of ProCEK4:CEK4-GUS cek4-1/-.

(A) to (F) Time-course GUS staining profile of germinating seeds. Seeds were stratified in sterile water for 1 d and then placed on Murashige and Skoog agar plates. Seeds upon imbibition ([A] and [B]), 1 d after imbibition (upon planting on a Murashige and Skoog plate) (C), 1 d after plating (D), 2 d after plating (E), and 3 d after plating (F).

(G) Five-day-old seedling.

(H) Ten-day-old seedling.

(I) Trichomes on the cotyledon of a 10-d-old seedling.

(J) Joint between roots and shoots.

(K) Branch of lateral roots.

(L) Root tip.

(M) A whole rosette of a bolting plant.

(N) An inflorescence stem.

(O) An inflorescence.

(P) Flowers at different developmental stages.

(Q) Developing siliques.

Bars = 500 μm in (A) to (L), 5 mm in (M) to (O), and 1 mm in (P) and (Q).
