The roles of three functional sulphate transporters involved in uptake and translocation of sulphate in Arabidopsis thaliana.
TLDR
Concomitant decrease of the tissue thiol content after selenate treatment was consistent with the suggested role of glutathione (GSH) as a repressive effector for the expression of sulphate transporter genes.
beta-Cyanoalanine synthase is a mitochondrial cysteine synthase-like protein in spinach and Arabidopsis.
TLDR
This is the first report of the identification of CAS synthase-encoding cDNAs in a living organism and a new nomenclature for CS-like proteins in plants is also proposed.

TLDR
This work states that O-acetylserine and glutathione presumably act within the cysteine synthesis pathway as derepressor and repressor, respectively, and a unique autoregulatory mechanism that stabilizes mRNA levels has recently been proposed for the regulation of methionine synthesis.
Regulation of sulfur assimilation in higher plants: a sulfate transporter induced in sulfate-starved roots plays a central role in Arabidopsis thaliana.
TLDR
The sulfate transporter (AST68) exhibited the most intensive and specific response in roots, indicating that AST68 plays a central role in the regulation of sulfate assimilation in plants.
Modulation of Cysteine Biosynthesis in Chloroplasts of Transgenic Tobacco Overexpressing Cysteine Synthase [O-Acetylserine(thiol)-Iyase]
TLDR
The results suggested that overaccumulated foreign CSase in chloroplasts could modulate biosynthetic flow of cysteine in response to sulfur stress.
Direct evidence for anthocyanidin synthase as a 2-oxoglutarate-dependent oxygenase: molecular cloning and functional expression of cDNA from a red forma of Perilla frutescens.
TLDR
It is shown that anthocyanidins are formed in vitro through 2-oxoglutarate-dependent oxidation of leucoanthocyanIDins catalyzed by the recombinant ANS and subsequent acid treatment.
Isoform-dependent Differences in Feedback Regulation and Subcellular Localization of Serine Acetyltransferase Involved in Cysteine Biosynthesis from Arabidopsis thaliana *
TLDR
The results suggest that these three SATase isoforms, which are localized in the different organelles, are subjected to different feedback regulation, presumably so as to play the particular roles for the production of OAS and cysteine in Arabidopsis cells.
Molecular biology of the plastidic phosphorylated serine biosynthetic pathway in Arabidopsis thaliana
TLDR
The results indicate that the plastidic 3-phosphoglycerate pathway plays an important role in supplying serine in non-photosynthetic tissues in plants and under environmental stresses.
Molecular Cloning and Biochemical Characterization of a Novel Anthocyanin 5-O-Glucosyltransferase by mRNA Differential Display for Plant Forms Regarding Anthocyanin*
TLDR
Several biochemical properties were similar to those reported previously for 5-GTs, includingoptimum pH,K m values, and sensitivity to inhibitors, and the identity of the cDNAs encoding 5- GT was isolated.
Structure and expression analyses of the S-adenosylmethionine synthetase gene family in Arabidopsis thaliana.
TLDR
Northern-blot analysis using gene-specific probes shows that both sam-1 and sam-2 are highly expressed in stem, root, and callus tissue, and this similar expression pattern might be mediated by the presence of three highly conserved sequences in the 5' region of both sam genes.
