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 ...
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 ...
