Molecular characterization and annotation of paralogous and orthologous genes in teleost early developmental stages

Abstract

Embryogenesis is one of the most critical periods for all organisms’ lifetime, during which a cascade of important processes are implemented. With an extra round of whole-genome duplication in teleosts and high paralogous gene retention rates related to development, their embryogenesis remains an appealing field for investigation. In the present thesis, the molecular basis of embryogenesis was investigated in a non-model (European seabass, Dicentrarchus labrax) and a model teleost (three-spined stickleback, Gasterosteus aculeatus). The collection of the expression profiles during early development was followed by the examination of the expression pattern of paralogous genes and their reflected role throughout embryogenesis. Moreover, the different expression profiles of miRNAs throughout early development of the two teleosts were studied. After investigating the transcriptomes it became apparent that key periods of early development are characterized by the expression of specific gene ...
