Figure 4.

CYP79F2 expression patterns monitored by GUS expression from the Ds gene trap insertion in the cyp79F2-2 allele. A, GUS-staining pattern detected in the root system of a 10-d-old seedling. The picture is the composite image of the aerial part and root system from the same seedling. B to D, Staining detected in the root of a 2-week-old seedling; B, At the region above root apical meristem; C, Staining is not detectable in more mature regions of the root. D, No GUS staining is detected in the root primodium.
