Assessing the regional conservation status of sponges (Porifera): the case of the Aegean ecoregion

open access: yes, 2018
Sponges are among the less-studied benthic invertebrates as regards their extinction risk and conservation status. Herein, we evaluate the regional conservation status of sponges in the Aegean ecoregion (Eastern Mediterranean Sea), using the IUCN Red ...

Evolution of g-type lysozymes in metazoa: insights into immunity and digestive adaptations

open access: yesFrontiers in Cell and Developmental Biology
Exploring the evolutionary dynamics of lysozymes is critical for advancing our knowledge of adaptations in immune and digestive systems. Here, we characterize the distribution of a unique class of lysozymes known as g-type, which hydrolyze key components

The largest reservoir of mitochondrial introns is a relic of an ancestral split gene [PDF]

open access: yes, 2010
In eukaryotes, introns are located in nuclear and organelle genes from several kingdoms (ref. 1-4). Large introns (0.1 to 5 kbp) are frequent in mitochondrial genomes of plant and fungi (ref.
