The EGFR pathway in Drosophila has become a model for understanding how signaling pathways are regulated with the precision that is necessary to control their multiple developmental and physiological roles (Shilo, 2003).
The multiple post-developmental roles for Rho in C. elegans demonstrate that RhoA signaling pathways continue to be used post-developmentally and the resulting phenotypes provide an opportunity to further study post-developmental Rho signaling pathways using genetic screens.
Our computational expression analyses suggest that many maize Hsf genes play functional developmental roles in multiple tissues.
The IRX genes, including IRX3 and IRX5, play complex and overlapping developmental roles in multiple tissues and organs [ 45, 46].
33 BvMYB genes (44%) were expressed in all samples analysed, which suggested that these BvMYBs play regulatory roles at multiple developmental stages.
A significant and somewhat surprising finding from this screen is the discovery that the CED-3 caspase has non-apoptotic roles in multiple developmental processes.
Most AtPP2C genes (84%) and OsPP2C genes (72%) were expressed in more than 2 tissues examined, suggesting that most PP2Cs in plants play functional roles at multiple developmental processes, and only a few members act in tissue-specific biological processes.
Genes targeted by those differentially expressed miRNAs (i.e. miR156, miR164, miR167, miR397, miR1861, and miR1867) were recognized to play roles in multiple developmental and signaling pathways related to plant hormone homeostasis and starch accumulation.
In soybean, only a small number (23 of 244; 9%) of the analyzed MYBs were constitutively expressed in all of the four tissues tested, which suggested that GmMYBs play regulatory roles at multiple developmental stages.
