Mechanisms explaining positional diversity of the hindlimb in tetrapod evolution

20:00 EDT 17 Aug 2017 | AAAS

(Nagoya University) Elucidating how body parts in their earliest recognizable form are assembled in tetrapods during development is essential for understanding the nature of morphological evolution. Nagoya University researchers found in eight tetrapod species that the position of the sacral vertebrae and the hindlimbs is determined by the initiation timing of Gdf11 gene expression. This will contribute to a forthcoming model explaining the coupling of spine and hindlimb positioning - a major step in fully understanding tetrapod evolution.

Gene Expression
The process of gene expression is used by eukaryotes, prokaryotes, and viruses to generate the macromolecular machinery for life. Steps in the gene expression process may be modulated, including the transcription, RNA splicing, translation, and post-tran...
