Promoter Activity of At MPB2C in Arabidopsis.
(A) to (E) Seedling and flower tissues of ProAtMPB2C:GUS plants stained for GUS activity.
(A) to (C) The promoter drives GUS production in the vasculature of cotyledons (A), tissue associated with leaf primordia, and apical meristem (B) and carpels (C).
(D) Weak GUS activity in ovules of ProAtMPB2C:GUS plants.
(E) Root tips of wild-type (control) and ProAtMPB2C:GUS plants.
(F) RT-PCR of At MPB2C and Actin as a control. Note the very low levels of At MPB2C transcripts relative to Actin in wild-type Arabidopsis Col-0 plants.
