Horizontal Transfer and Gene Loss Shaped the Evolution of Alpha-Amylases in Bilaterians

open access: yesG3: Genes, Genomes, Genetics, 2020
The subfamily GH13_1 of alpha-amylases is typical of Fungi, but it is also found in some unicellular eukaryotes (e.g., Amoebozoa, choanoflagellates) and non-bilaterian Metazoa.

Brachiopod and mollusc biomineralisation is a conserved process that was lost in the phoronid–bryozoan stem lineage

open access: yesEvoDevo, 2022
Background Brachiopods and molluscs are lophotrochozoans with hard external shells which are often believed to have evolved convergently. While palaeontological data indicate that both groups are descended from biomineralising Cambrian ancestors, the ...
