Avian eggshell biomineralization: an update on its structure, mineralogy and protein tool kit

open access: yesBMC Molecular and Cell Biology, 2021
Background The avian eggshell is a natural protective envelope that relies on the phenomenon of biomineralization for its formation. The shell is made of calcium carbonate in the form of calcite, which contains hundreds of proteins that interact with the

Fungal biomineralization

open access: yesCurrent Biology, 2021
Fungi are key organisms of the biosphere with major roles in organic-matter decomposition, element cycling, plant pathogenicity, and symbioses in aquatic and terrestrial habitats. The vast majority exhibit a filamentous, branching growth form and are aerobic chemoorganotrophs that derive carbon and energy from organic substances, and are particularly ...
