Mediator Subunit18 Controls Flowering Time and Floral Organ Identity in Arabidopsis
Figure 2
(A–D) Longitudinal sections of wild type show MED18 mRNA detected in (A) developing seed, (B) inflorescence meristem, floral meristem and sepals, (C, D) petal, stamen, and carpel primordia. (E) Transverse section of a wild type flower shows MED18 mRNA expression in all floral organs. (F) MED18 mRNA sense strand control showing no non-specific hybridization. Numbers in B–D and F indicate flower stages; IM in B and F indicates inflorescence meristem. Scale bars: 100 µm in B–F and 25 µm in A.
