Biochim Biophys Acta Bioenerg
. 2024 Jul;
1865(4):149495.
PMID: 39004113
Current views of O accumulation in Earth history depict three phases: The onset of O production by ∼2.4 billion years ago; 2 billion years of stasis at ∼1 % of...

FEBS Lett
. 2024 May;
598(14):1692-1714.
PMID: 38750628
Molecular oxygen is a stable diradical. All O-dependent enzymes employ a radical mechanism. Generated by cyanobacteria, O started accumulating on Earth 2.4 billion years ago. Its evolutionary impact is traditionally...

Preiner M, Xavier J, do Nascimento Vieira A, Kleinermanns K, Allen J, Martin W
Interface Focus
. 2019 Oct;
9(6):20190072.
PMID: 31641438
If life on Earth started out in geochemical environments like hydrothermal vents, then it started out from gasses like CO, N and H. Anaerobic autotrophs still live from these gasses...

Allen J, Thake B, Martin W
Trends Plant Sci
. 2019 Aug;
24(11):1022-1031.
PMID: 31447302
Cyanobacteria produced the oxygen that began to accumulate on Earth 2.5 billion years ago, at the dawn of the Proterozoic Eon. By 2.4 billion years ago, the Great Oxidation Event...

Allen J, Nield J, Krauss N
Trends Plant Sci
. 2019 Apr;
24(5):388-392.
PMID: 30930004
True to its name, light-harvesting complex II (LHC II) harvests light energy for photosystem II (PS II). However, LHC II can stray, harvesting light energy for photosystem I (PS I)...

Cell
. 2018 Jul;
174(2):256-258.
PMID: 30007415
Photosynthetic eukaryotes arose ∼1.5 billion years ago by endosymbiosis with a cyanobacterium. Algae then evolved for a billion years before one lineage finally colonized land. Why the wait? The Chara...

Protoplasma
. 2018 Jan;
255(3):937-952.
PMID: 29290041
Two-component signal transduction systems (TCSs) consist of sensor histidine kinases and response regulators. TCSs mediate adaptation to environmental changes in bacteria, plants, fungi and protists. Histidine kinase 2 (Hik2) is...

Allen J
J Theor Biol
. 2017 Apr;
434:50-57.
PMID: 28408315
Chloroplasts and mitochondria perform energy transduction in photosynthesis and respiration. These processes can be described in physico-chemical terms with no obvious requirement for co-located genetic systems, separat from those of...

Physiol Plant
. 2017 Apr;
161(1):28-44.
PMID: 28393369
In oxygenic photosynthesis there are two 'light states' - adaptations of the photosynthetic apparatus to spectral composition that otherwise favours either photosystem I or photosystem II. In chloroplasts of green...
