The UV-B induced formation of thymine cis-syn cyclobutane dimer and related (6-4) photoproduct was monitored within DNA of cultured cells and plants of Arabidopsis thaliana. This was achieved using a sensitive and accurate HPLC-tandem mass spectrometry assay. It was found that the cyclobutane

BACKGROUND
Deoxyuridine triphosphate nucleotidohydrolase (dUTPase) hydrolyzes dUTP to dUMP and pyrophosphate to maintain the cellular thymine-uracil ratio. dUTPase is also a target for cancer chemotherapy. However, the mechanism defining its substrate affinity remains unclear. Sequence comparisons

Plant organelles cope with endogenous DNA damaging agents, byproducts of respiration and photosynthesis, and exogenous agents like ultraviolet light. Plant organellar DNA polymerases (DNAPs) are not phylogenetically related to yeast and metazoan DNAPs and they harbor three insertions not present in
The mutagenicity of azido derivatives of monosaccharides and alcohols and of N-(3-azido-2-hydroxypropyl) derivatives of purines and pyrimidines in Arabidopsis thaliana and in Salmonella typhimurium.

The azido derivatives of alcohols (3-azido-1,2-propandiol and 1,3-diazido-2-propanol) and monosaccharides (6-azido-6-deoxy-beta-D-glucose and 6-azido-6-deoxy-beta-D-galactose), as well as the proximal mutagenic product of sodium azide metabolism beta-azido-L-alanine, exhibited a high mutagenic
Analysis of UV-induced mutation spectra in Escherichia coli by DNA polymerase eta from Arabidopsis thaliana.

DNA polymerase eta belongs to the Y-family of DNA polymerases, enzymes that are able to synthesize past template lesions that block replication fork progression. This polymerase accurately bypasses UV-associated cis-syn cyclobutane thymine dimers in vitro and therefore may contributes to resistance

Cryptochromes use near-UV/blue light to regulate a variety of growth and adaptive process. Recent biochemical studies demonstrate that the Cryptochrome-Drosophila, Arabidopsis, Synechocystis, Human (Cry-DASH) subfamily of cryptochromes have photolyase activity exclusively for single-stranded

Reactive oxygen species (ROS) are ubiquitous DNA-damaging agents, and the repair of oxidative DNA lesions is essential to prevent mutations and cell death. Escherichia coli endonuclease III is the prototype repair enzyme for removal of oxidized pyrimidines from DNA. A database homology search

To reveal the mutation effect of low-energy ion implantation on Ambidopsis thaliana in vivo, T80II, a stable dwarf mutant, derived from the seeds irradiated by 30 keV N(+) with the dose of 80 X 10(15) ions/cm(2) was used for Random Amplified Polymorphic DNA (RAPD) and base sequence analysis. The

Methyl-CpG-binding domain 4 (MBD4) DNA glycosylase is involved in excision of spontaneous deamination products of cytosine and 5-methylcytosine in animals, but it is unknown whether related proteins perform similar functions in plants. We report here the isolation and biochemical characterization of

CONCLUSIONS
The AHAS gene family in soybean was characterized. The locus Als1 for sulfonylurea resistance was mapped and the resistant allele was characterized at the molecular level. Sulfonylurea (SU) resistance in soybean is controlled by Als1, a semi-dominant allele obtained by EMS mutagenesis

Metabolites regulate their own production by directly interacting with highly conserved regions of mRNA that are capable of forming discrete tertiary structures. Such regions of mRNA are called riboswitches. The thiamine pyrophosphate (TPP) riboswitch is the most common riboswitch in different

Arabidopsis thaliana repressor of silencing 1 (ROS1) is a multi-domain bifunctional DNA glycosylase/lyase, which excises 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) as well as thymine and 5-hydroxymethyluracil (i.e., the deamination products of 5mC and 5hmC) when paired with a guanine,
PerPlot & PerScan: tools for analysis of DNA curvature-related periodicity in genomic nucleotide sequences.

BACKGROUND
Periodic spacing of short adenine or thymine runs phased with DNA helical period of ~10.5 bp is associated with intrinsic DNA curvature and deformability, which play important roles in DNA-protein interactions and in the organization of chromosomes in both eukaryotes and prokaryotes.

To assess how evolution might have biochemically shaped DNA polymerase eta (Poleta) in plants, we expressed in Escherichia coli proteins from Arabidopsis thaliana (At), humans (Hs), and the yeast Saccharomyces cerevisiae (Sc), purified them to near homogeneity, and compared their properties.
