We studied the effects of low concentrations of quercetin on the contents of sugars and amino acids in ripe tomato (Lycopersicon esculentumMill.) fruits. In treated plants, the content of glucose increased by 1.5–4.5 times, whereas the total content of amino acids decreased by 1.5 times. The glucogenic amino acids, glutamic and aspartic acid, decreased most substantially, viz. by 1.7 and 1.6 times, respectively. The mechanism of the quercetin-induced enhancement of gluconeogenesis and…

Polyphenol distribution in plant organs of tomato introgression lines
TLDR
Among genotypes few differences in polyphenols were recorded on fresh weight basis; however, this seems to depend on the lower water content rather than on a higher polyphenol biosynthesis in the genotype.
Response of Tomato Fruit Quality Depends on Period of LED Supplementary Light
Light is an important environmental factor that regulates the activity of metabolism-related biochemical pathways during tomato maturation. Using LED to improve lighting conditions during the process…

Inhibition of CUTIN DEFICIENT 2 Causes Defects in Cuticle Function and Structure and Metabolite Changes in Tomato Fruit.
TLDR
Results indicate that CD2 is essential both for normal cutin and wax deposition and for proper accumulation of specific metabolites in tomato fruit.

TLDR
Quercetin and its oxidized form are shown to inhibit the electron transfer in the PS(2) acceptor and donor sites, respectively, and function as an electron donor or and electron acceptor in PS(1).

TLDR
The capabilities of peroxisomal involvement in the gluconeogenetic processes of vertebrate animals are reviewed and it is demonstrated that the participation of this organelle affords the potential of alternative pathways for the conversion of triacylglycerols to glucose, and for the Conversion of amino acids and lactate to carbohydrate.
A reassessment of glycolysis and gluconeogenesis in higher plants
TLDR
During both glycolysis and gluconeogenesis alternative enzymes are present at various steps to carry out parallel pathways; alternatives are available for utilizing nucleotide triphosphates and pyrophosphate; fructose 2,6-bisphosphate serves as a strong internal regulator; and plants use these cytoplasmic alternatives as they develop and as their environments change.

Lipid mobilization and gluconeogenesis in plants: do glyoxylate cycle enzyme activities constitute a real cycle? A hypothesis.
TLDR
Experimental evidence based on the active metabolic roles of higher plant glyoxysomes and yeast peroxisomes suggests the coexistence of two mechanisms, namely a reductase/peroxidase membrane redox chain and a malate/aspartate shuttle susceptible to transfer electrons to the mitochondrial ATP generating system.

Ion Exchange Chromatography of Amino Acids
TLDR
An apparatus for the determination of amino acids by ion exchange chromatography has a reasonable claim to being automatic, but like all other procedures thus far deit fails to go beyond analogue presentation of data.
