How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2
Plant, Cell &Environment, EarlyView.ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

A proposal for climate stability on H2-greenhouse planets
, 2015 A terrestrial planet in an orbit far outside of the standard habitable zone could maintain surface liquid water as a result of H2-H2 collision-induced absorption by a thick H2 atmosphere.

Metabolic versatility in methanogens
Current Opinion in Biotechnology, 2014 Methanogenesis is an anaerobic metabolism responsible for the generation of >90% of the methane formed on Earth today, with important implications for fuels production and global warming. Although methanogenic Archaea have been cultured for over 70 years, key insights regarding electron flow and energy conservation in methanogenesis have only recently ...

Sedimentology, EarlyView.ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

Microbial co-existence and stable equilibria in a mechanistic model of enteric methane production : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Mathematics at Massey University, Manawatū Campus, New Zealand [PDF]
, 2016 Globally, 14.5% of all anthropogenic greenhouse gases come from ruminants. One of these is methane, which is produced in the rumen of ruminant animals. Feed is degraded by microbes to produce volatile fatty acids (which are absorbed by the animal) and

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria
Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Physiological Evidence for Isopotential Tunneling in the Electron Transport Chain of Methane-Producing Archaea [PDF]
, 2017 Many, but not all, organisms use quinones to conserve energy in their electron transport chains. Fermentative bacteria and methane-producing archaea (methanogens) do not produce quinones but have devised other ways to generate ATP. Methanophenazine (MPh)
