PLANT UNCOUPLING MITOCHONDRIAL PROTEIN 2 localizes to the Golgi
(Oxford University Press; American Society of Plant Biologists, 2023-10-11)
Mitochondria act as cellular hubs of energy transformation and metabolite conversion in most ukaryotes. Plant mitochondrial electron transport chains are particularly flexible, featuring components that ...
The Lack of Alternative Oxidase 1a Restricts in vivo Respiratory Activity and Stress-Related Metabolism for Leaf Osmoprotection and Redox Balancing Under Sudden Acute Water and Salt Stress in Arabidopsis thaliana
(Frontiers Media, 2022-05-17)
In plants salt and water stress result in an induction of respiration and accumulation of stress-related metabolites (SRMs) with osmoregulation and osmoprotection functions that benefit photosynthesis. ...
Overexpression of thioredoxin m in chloroplasts alters carbon and nitrogen partitioning in tobacco
(Oxford University Press, 2021-05-08)
In plants, there is a complex interaction between carbon (C) and nitrogen (N) metabolism, and its coordination is fundamental for plant growth and development. Here, we studied the influence of thioredoxin ...
Several geranylgeranyl diphosphate synthase isoforms supply metabolic substrates for carotenoid biosynthesis in tomato
(Wiley, 2021-02-16)
Geranylgeranyl diphosphate (GGPP) produced by GGPP synthase (GGPPS) serves as a precursor for many plastidial isoprenoids, including carotenoids. Phytoene synthase (PSY) converts GGPP into phytoene, the ...
Cytochrome c Deficiency Differentially Affects the In Vivo Mitochondrial Electron Partitioning and Primary Metabolism Depending on the Photoperiod
(MDPI, 2021-02-26)
Plant respiration provides metabolic flexibility under changing environmental conditions by modulating the activity of the nonphosphorylating alternative pathways from the mitochondrial electron transport ...
Metabolomic analyses of highbush blueberry (Vaccinium corymbosum L.) cultivars revealed mechanisms of resistance to aluminum toxicity
(Elsevier, 2020-12-02)
Aluminum (Al) is an important factor that limits plant growth under acidic soil conditions. However, several
plant species developed distinct mechanisms that limit the damage caused by high Al ...
Decreased levels of Thioredoxin o1 influences stomatal development and aperture but not Photosynthesis under non-stress and saline conditions
(MDPI, 2021-01-21)
Salinity has a negative impact on plant growth, with photosynthesis being downregulated partially due to osmotic effect and enhanced cellular oxidation. Redox signaling contributes to the plant response ...
Light signals generated by vegetation shade facilitate acclimation to low light in shade-avoider plants
(American Society of Plant Biologists, 2021-05-07)
When growing in search for light, plants can experience continuous or occasional shading by other plants. Plant proximity causes a decrease in the ratio of R to far-red light (low R:FR) due to the ...
Different Metabolic Roles for Alternative Oxidase in Leaves of Palustrine and Terrestrial Species
(Frontiers Media, 2021-11-04)
The alternative oxidase pathway (AOP) is associated with excess energy dissipation
in leaves of terrestrial plants. To address whether this association is less important
in palustrine plants, we ...
