FOUR NEW SPECIES OF ACANTHOBOTHRIUM (CESTODA: TETRAPHYLLIDEA) FROM THE WHIPTAIL STINGRAY DASYATIS BREVIS IN THE GULF OF CALIFORNIA, MEXICO
TLDR
Examination of the spiral intestines of 29 whiptail stingrays from 6 sites in the Gulf of California, México in 1993 and 1996 resulted in the discovery of 4 new species of Acanthobothrium, the first record of either of these genera of onchobothriid tapeworms from the gulf of California.
Molecular evolution of glutamine synthetase II: Phylogenetic evidence of a non-endosymbiotic gene transfer event early in plant evolution
TLDR
Phylogenetic evidence suggests GSIIB in Chloroplastida evolved by HGT, possibly after the divergence of the primary endosymbiotic lineages, and the isoenzymes may have evolved via different evolutionary processes.
MOLECULAR EVOLUTION OF GLUTAMINE SYNTHETASE II AND III IN THE CHROMALVEOLATES 1
TLDR
The evolutionary history of the GS gene families within the algae is complex with evidence for the presence of orthologous and paralogous sequences, ancient and recent gene duplications, gene losses and replacements, and the potential for both endosymbiotic and lateral gene transfers.
Molecular Evolution of Nitrogen Assimilatory Enzymes in Marine Prasinophytes
TLDR
The results show that genes encoding the nitrogen-assimilating enzymes in Micromonas and Ostreococcus have been differentially lost and as well as recruited from different evolutionary lineages, suggesting that the regulation of nitrogen assimilation in prasinophytes will differ from other green algae.
