A hot origin of dissimilatory sulfite reduction catalyzed by DsrAB in the Paleoarchean Era
mLife, Volume 5, Issue 1, Page 108-121, February 2026.Abstract Dissimilatory sulfite reduction (DSR) has been essential to microbial energy metabolism in the biogeochemical sulfur cycle since the Paleoarchean Era. However, due to the lack of an integrated assessment of geological record and genomic data, the evolutionary origin of DSR remains elusive in terms of time, habitat, and genetic basis.

Seasonal Changes in Marine Archaeal Tetraether Lipid Export Depth Linked to Net Primary Productivity
Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.Abstract Marine ammonia oxidizing archaea (AOA) produce isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) which form the basis of seawater temperature proxy TEX86. Although most studies use TEX86 for sea surface temperature (SST) reconstructions, maximum GDGT production occurs at and below the nitracline. Moreover, sedimentary GDGT‐2/GDGT‐3

Archaea, 2006 The publicly available annotated archaeal genome sequences (23 complete and three partial annotations, October 2005) were searched for the presence of potential two‐component open reading frames (ORFs) using gene category lists and BLASTP. A total of 489 potential two‐component genes were identified from the gene category lists and BLASTP.
