Figure 1. Expression of AtCRT1a, CRT1b and CRT3.

Figure 1

Expression patterns of the AtCRT1a, CRT1b, and CRT3 genes assessed through promoter:GUS constructs. The GUS expression is indicated by blue colour. A to C. Six-day-old seedlings expressing GUS-constructs for AtCRT1a (A), CRT1b (B), and CRT3 (C). Root tip images for the different lines are represented as inserts. Arrows indicate expression in the root tips. D to F. Floral tissues from five week-old plants expressing GUS-constructs for AtCRT1a (D), CRT1b (E), and CRT3 (F). Arrows indicate GUS activity in the pollen. G to I. Two-day-old seedlings expressing GUS-constructs for AtCRT1a (G), CRT1b (H), and CRT3 (I). Arrows indicate GUS activity in the roots. J to L. Etiolated six-day-old seedlings expressing GUS-constructs for AtCRT1a (J), CRT1b (K), and CRT3 (L). Inserts indicate GUS expression in the cotyledons. M to O. Rosette leaves from four-week-old plants expressing GUS-constructs for AtCRT1a (M), CRT1b (N), and CRT3 (O). P and Q. Senescing leaves (from eight-week-old plants) expressing GUS-constructs for AtCRT1a (P), and CRT3 (Q).
