|The AGL15 MADS-box gene is highly expressed in developing embryos, specifically in the embryo proper. We did not detect AGL15 RNA in the suspensor cells.||
|We first detected AGL15 RNA
(yellow) at the 8-cell stage of embryo development, as shown below.
The next images show the embryo at the dermatogen stage. Notice the strong uniform accumulation of AGL15 RNA throughout the embryo, and the lack of expression in the suspensor.
This uniform expression of AGL15 RNA is maintained throughout embryo development and seedling germination.
