It is used to identify distinct cell groups in fly development and also in vertebrate development for example the "optic anlagen" is the group of cells that will become the eye in many vertebrates.

These DL expression domains corresponded to the presumptive region (carpel anlagen), where carpel primordia would initiate. Shortly after this expression, carpel primordia began to form. At this stage, DL was expressed specifically and uniformly in carpel primordia (Figures 4G to 4I). No expression was detected in the flower meristem (Figures 4E and 4F) or the ovule primordium (Figures 4G to 4I). By contrast, expression of DL was not observed in dl-sup1 mutants throughout flower development (data not shown). Thus, the expression domains of DL are restricted to the carpel anlagen and the carpel primordia, and these expression patterns of DL are consistent with its specific role in carpel development.'</DIV><DIV style="margin-top: 0px;
