Anatomical variations along the leaf axis modulate photosynthetic responses of sorghum and maize under different water availabilities

Plant Biology, EarlyView.
The middle part of C4 leaves is more anatomically and photochemically drought‐adapted than the apex or base. Water limitation did not negatively effect leaf anatomy and photosynthesis in sorghum, but reduced gas exchange and the thickness of leaf tissues in maize.

Improvement of succinate production from methane by combining rational engineering and laboratory evolution in Methylomonas sp. DH-1

Microbial Cell Factories
Recently, methane has been considered a next-generation carbon feedstock due to its abundance and it is main component of shale gas and biogas. Methylomonas sp. DH-1 has been evaluated as a promising industrial bio-catalyst candidate.

Laying the Foundation for Crassulacean Acid Metabolism (CAM) Biodesign: Expression of the C4 Metabolism Cycle Genes of CAM in Arabidopsis

Frontiers in Plant Science, 2019
Crassulacean acid metabolism (CAM) is a specialized mode of photosynthesis that exploits a temporal CO2 pump with nocturnal CO2 uptake and concentration to reduce photorespiration, improve water-use efficiency (WUE), and optimize the adaptability of ...

Bacterial- and plant-type phosphoenolpyruvate carboxylase isozymes from developing castor oil seeds interact in vivo and associate with the surface of mitochondria.

The Plant Journal, 2012
Phosphoenolpyruvate carboxylase (PEPC) from developing castor oil seeds (COS) exists as two distinct oligomeric isoforms. The typical class-1 PEPC homotetramer consists of 107-kDa plant-type PEPC (PTPC) subunits, whereas the allosterically desensitized ...

Pyruvate Carboxylase in Macrophages Aggravates Atherosclerosis by Regulating Metabolism Reprogramming to Promote Inflammatory Responses Through the Hypoxia‐Inducible Factor‐1 Signaling Pathway

Advanced Science, Volume 12, Issue 29, August 7, 2025.
This study investigates the role of macrophage pyruvate carboxylase (PC) in atherosclerosis (AS) demonstrating that PC upregulation in macrophages promotes metabolism reprogramming to enhance inflammatory responses via the HIF‐1 signaling pathway.

The PEP—pyruvate—oxaloacetate node as the switch point for carbon flux distribution in bacteria: We dedicate this paper to Rudolf K. Thauer, Director of the Max-Planck-Institute for Terrestrial Microbiology in Marburg, Germany, on the occasion of his 65th birthday [PDF]

, 2017
In many organisms, metabolite interconversion at the phosphoenolpyruvate (PEP)-pyruvate-oxaloacetate node involves a structurally entangled set of reactions that interconnects the major pathways of carbon metabolism and thus, is responsible for the ...

Which way does the citric acid cycle turn during hypoxia? The critical role of alpha-ketoglutarate dehydrogenase complex [PDF]

, 2013
The citric acid cycle forms a major metabolic hub and as such it is involved in many disease states involving energetic imbalance. In spite of the fact that it is being branded as a "cycle", during hypoxia, when the electron transport chain does not ...

An INS‐1 832/13 𝛽‐Cell Proteome Highlights the Rapid Regulation of Fatty Acid Biosynthesis in Glucose‐Stimulated Insulin Secretion

PROTEOMICS, Volume 25, Issue 15, Page 13-26, August 2025.
ABSTRACT Pancreatic beta cells secrete insulin in response to rising glucose levels, a process known as glucose‐stimulated insulin secretion (GSIS). Here, we acquire proteomes of rat pancreatic INS‐1 832/13 beta cells that were short‐term stimulated with 11 different glucose concentrations from 0 to 20 mM, quantifying the response of 3703 proteins ...

C3 Compound Metabolism in the Thermoacidophilic Methanotroph Methylacidiphilum fumariolicum SolV

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Terrestrial and oceanic geothermal areas emit substantial amounts of small hydrocarbons. The thermoacidophilic verrucomicrobial methanotroph Methylacidiphilum fumariolicum SolV, isolated from the Solfatara volcano, was shown to grow on 2‐propanol and acetone using steady‐state continuous cultures.
