Fig. 6. Tec29 is necessary to delay endoreplication in the salivary glands. There are more BrdU-labeled nuclei in the invaginated gland labeled with FKH antibody (green) at early stage 12 in Tec29^K00206 compared with w¹¹¹⁸ (A,B, arrowhead) and also ventrally in the salivary placodes at mid stage 12 (arrowhead, compare E with F). In addition, there are more BrdU labeled nuclei in Tec29^K00206chic²²¹ embryos compared with Tec29^K00206 alone at early stage 12 (C) and at mid stage 12 (G). BrdU labeling in Tec29^K00206tsr^K05633 is similar to Tec29^K00206 embryos (D,H). (I,J) Delaying endoreplication by driving UAS-CycE using prd-GAL4 in Tec29^K00206 embryos rescues the long salivary gland phenotype of Tec29^K00206 embryos (arrows).
