Overexpression of S-Adenosyl-l-Methionine Synthetase 2 from Sugar Beet M14 Increased Arabidopsis Tolerance to Salt and Oxidative Stress

Overexpression of S-Adenosyl-l-Methionine Synthetase 2 from Sugar Beet M14 Increased Arabidopsis Tolerance to Salt and Oxidative Stress

The sugar beet monosomic addition line M14 is a unique germplasm that contains genetic materials from Beta vulgaris L. and Beta corolliflora Zoss, and shows tolerance to salt stress. Our study focuses on exploring the molecular mechanism of the salt tolerance of the sugar beet M14. In order to identify differentially expressed genes in M14 under salt stress, a subtractive cDNA library was gener...

A cDNA encoding S-adenosyl-L-methionine synthetase from poplar.

Adomet synthetase (EC 2.5.1.6) catalyzes the formation of Adomet, which serves as a methyl group donor in highly specific transmethylation reactions involving a11 kinds of acceptor molecules such as proteins, nucleic acids, phenylpropanoid derivatives, polysaccharides, cyclic fatty acids, etc. Adomet also plays a role in amino acid biosynthesis and polyamine biosynthesis. In plants, Adomet has ...

An S-adenosyl Methionine Synthetase (SAMS) Gene from Andropogon virginicus L. Confers Aluminum Stress Tolerance and Facilitates Epigenetic Gene Regulation in Arabidopsis thaliana

Candidate clones which conferred Al tolerance to yeast transformants (TFs) were obtained from a cDNA library derived from a highly Al-tolerant poaceae, Andropogon virginicus L. One such clone, AL3A-4, encoded an S-adenosyl methionine synthetase (SAMS) gene. A full-length cDNA was obtained by 5'-RACE, designated AvSAMS1, and introduced into Arabidopsis thaliana to investigate its biological func...

Interleukin-2 induces gamma-S-adenosyl-L-methionine synthetase gene expression during T-lymphocyte activation.

The regulation of expression of the gamma-S-adenosyl-L-methionine (AdoMet) synthetase gene was investigated in T-cells during G0/G1 transition, as well as throughout the G1 phase. Stimulation of G0 T-lymphocytes with concanavalin A induces AdoMet synthetase gene expression, starting 8 h after stimulation. Interleukin-2 (IL-2) stimulates the induction of this gene expression and AdoMet synthetas...
