The discovery of four genes of the Noggin family in lampreys is consistent with the hypothesis of two rounds of genomic duplications in vertebrate ancestors
Researchers from the Laboratory of Molecular Bases of Embryogenesis, together with a colleague from the Severtsov Institute of Ecology and Evolution, described for the first time four genes of the Noggin family in the oldest representatives of vertebrates - lampreys, and compared their structure, expression and some functional features with those of the known genes of this family in other vertebrates. As a result, it was concluded that the entire set of the data obtained is in the best agreement with the hypothesis of two successive rounds of duplications of the ancestral genome of invertebrates that occurred at the earliest stage of vertebrate evolution. The work was published in the new journal of Nature Publishing Group - Communications Biology. Learn more
