Abstract
The organization of the olfactory glomerular map involves the convergence of olfactory sensory neurons (OSNs) expressing the same odorant receptor (OR) into glomeruli in the olfactory bulb (OB). A remarkable feature of the olfactory glomerular map formation is that the identity of OR instructs the topography of the bulb, resulting in thousands of discrete glomeruli in mice. Several lines of evidence indicate that ORs control the expression levels of various kinds of transmembrane proteins to form glomeruli at appropriate regions of the OB. In this review, we will discuss how the OR identity is decoded by OSNs into gene expression through intracellular regulatory mechanisms.
期刊介绍：
As of January 2000, Developmental Genetics was renamed and relaunched as genesis: The Journal of Genetics and Development, with a new scope and Editorial Board. The journal focuses on work that addresses the genetics of development and the fundamental mechanisms of embryological processes in animals and plants. With increased awareness of the interplay between genetics and evolutionary change, particularly during developmental processes, we encourage submission of manuscripts from all ecological niches. The expanded numbers of genomes for which sequencing is being completed will facilitate genetic and genomic examination of developmental issues, even if the model system does not fit the “classical genetic” mold. Therefore, we encourage submission of manuscripts from all species. Other areas of particular interest include: 1) the roles of epigenetics, microRNAs and environment on developmental processes; 2) genome-wide studies; 3) novel imaging techniques for the study of gene expression and cellular function; 4) comparative genetics and genomics and 5) animal models of human genetic and developmental disorders.
genesis presents reviews, full research articles, short research letters, and state-of-the-art technology reports that promote an understanding of the function of genes and the roles they play in complex developmental processes.
