alcohol dehydrogenase/arabidopsis thaliana

Nucleotide variation at the alcohol dehydrogenase locus (Adh) was studied in the outcrossing Arabidopsis lyrata, a close relative of the selfing Arabidopsis thaliana. Overall, estimated nucleotide diversity in the North American ssp. lyrata and two European ssp. petraea populations was 0.0038, lower

Although considerable research and speculation have been directed toward understanding a plant's perception of gravity and the resulting gravitropic responses, little is known about the role of gravity-dependent physical processes in normal physiological function. These studies were conducted to

Proper exchange of atmospheric gases is important for normal root and shoot metabolism in plants. This study was conducted to determine how restricted air supply affects foliar carbohydrates, while using the marker enzyme alcohol dehydrogenase (ADH) to report on the oxygenation status of the

Arabidopsis thaliana provides an excellent experimental plant system for molecular genetics because of its remarkably small genome size, near absence of dispersed middle repetitive DNA, and short life cycle. We have cloned and determined the nucleotide sequence of a single-copy gene from A. thaliana

We designate a region of the alcohol dehydrogenase locus (Adh) of the weedy crucifer, Arabidopsis thaliana, as "hypervariable" on the basis of a comparison of sequences from ecotypes Columbia and Landsberg. We found eight synonymous and two replacement mutations in the first 262 nucleotides of exon

The vascular tissue of roots performs essential roles in the physical support and transport of water, nutrients, and signaling molecules in higher plants. The molecular mechanisms underlying the function of root vascular tissue are poorly understood. In this study, we analyzed the expression pattern

In plant cells, many stresses, including low oxygen availability, result in a higher production of reactive oxygen species (ROS) and reactive nitrogen species (RNS). These molecules can lead to redox-dependent post-translational modification of proteins Cys residues. Here, we studied the effect of

Several mutants have been isolated at the Arabidopsis thaliana (L.) Heynh. alcohol dehydrogenase (ADH) gene locus using allyl alcohol selection on ethyl methanesulfonate (EMS)-mutagenized seeds. Eleven mutants were isolated in the ADH1-A electrophoretic allele, and 21 in the ADH1-S allele. These

mRNA encoding alcohol dehydrogenase (ADH) increases in etiolated seedlings and leaves of Arabidopsis thaliana (L.) Heynh. upon exposure to low temperature. The analysis of this response after water stress and abscisic acid (ABA) treatments in Arabidopsis wild type and ABA-deficient and -insensitive

A major goal currently in Arabidopsis research is determination of the (biochemical) function of each of its approximately 27,000 genes. To date, however, 12% of its genes actually have known biochemical roles. In this study, we considered it instructive to identify the gene expression patterns of

Zymograms of Arabidopsis alcohol dehydrogenase (ADH; EC 1.1.1.1) show a unique anodal migrating band. Three electrophoretic variants were identified among geographical races and designated slow (S), fast (F), and superfast (A), according to their mobility on Tris-citrate starch gels. In plants ADH

Alcohol dehydrogenase (ADH, EC 1.1.1.1) plays important roles in the metabolism of alcohols and aldehydes. They are often subjected to conformational changes that are critical for the enzymatic activity and have received intensive investigation for horse liver ADH. However, for the large plant ADH

Alcohol dehydrogenases (ADH) catalyze the interconversion between alcohols and aldehydes with the reduction of nicotinamide adenine dinucleotide (NAD(+)) to NADH. In this study, for the first time we report an over-expression and purification strategy for the Arabidosis thaliana ADH (AtADH), and
