Commercially available dry dog foods are often manufactured using extrusion cooking. Normal extrusion conditions can promote Maillard reactions involving the amino acid lysine. This non-enzymatic browning reaction occurs between a carbonyl group and an amino group in a diet. This study investigated the influence of a number of extrusion...

Different aspects of androgenesis induction have been studied in detail, but little is known about the molecular mechanisms associated with this developmental switch. We have employed macroarrays containing 1421 expressed sequence tags covering the early stages of barley zygotic embryogenesis to compare the gene expression profiles of stress...

Following abiotic stress to induce barley (Hordeum vulgare L.) androgenesis, the development of 794 enlarged microspores in culture was monitored by time-lapse tracking. In total, 11% of the microspores tracked developed into embryo-like structures (type-I pathway), 36% formed multicellular structures (type-II pathway) and 53% of the microspores...

Androgenesis represents one of the most fascinating examples of cell differentiation in plants. In barley, the conversion of stressed uninucleate microspores into embryo-like structures is highly efficient. One of the bottlenecks in this process is the successful release of embryo-like structures out of the exine wall of microspores. In the...

Germination of seeds proceeds in general in two phases, an initial imbibition phase and a subsequent growth phase. In grasses like barley, the latter phase is evident as the emergence of the embryonic root (radicle). The hormone abscisic acid (ABA) inhibits germination because it prevents the embryo from entering and completing the growth phase....

We developed an approach for relating differences in gene expression to the phenotypic variation of a trait of interest. This allows the identification of candidate genes for traits that display quantitative variation. To validate the principle, gene expression was monitored on a cDNA array with 1400 ESTs to identify genes involved in the...

The cholesterol-lowering effect observed following consumption of oats and barley is attributable to the β-glucan component of the soluble fiber fraction of these cereal grains. β-Glucan has also been reported to modulate immune activity, however, few studies have evaluated the hematological effects of β-glucan following oral exposure. In the...

The members of the 14-3-3 isoform family have been shown to be developmentally regulated during animal embryogenesis, where they take part in cell differentiation processes. 14-3-3 isoform-specific expression patterns were studied in plant embryogenic processes, using barley (Hordeum vulgare L.) microspore embryogenesis as a model system. After...

Conserved 14-3-3 proteins have been shown to play regulatory roles in eukaryotic cells, including cell cycle control and differentiation. We were interested in the possible involvement of 14-3-3 proteins in the embryogenic process of barley (Hordeum vulgare L.). Barley microspore-derived embryo development was used as a model system....

β-Glucans are water-soluble cell-wall polysaccharides consisting of (1→3,1→4)-linked β-D-glucopyranosyl monomers that comprise a considerable proportion of soluble fiber from certain grains including oats and barley. Consumption of foods containing β-glucan or β-glucan-enriched fractions prepared from these grains lower serum cholesterol...

Over the past few years the presence of p53-like proteins in plants was frequently reported, by using the monoclonal antibody Pab240. By means of protein purification and screening a cDNA library, a Pab240 cross-reacting protein and a cDNA clone were isolated from barley. Peptide- and DNA-sequence analysis identified one and the same protein: 2...

We have identified the major endo-β-l,4-xylanase (XYN-1) in the aleurone of germinating barley grain, and show that it is expressed as a precursor of Mr 61 500 with both N- and C-terminal propeptides. XYN-1 is synthesized as an inactive enzyme in the cytoplasm, and only becomes active at a late stage of germination when the aleurone ceases to...

Associations between lipoxygenases (Lox) and 14-3-3 proteins were demonstrated by two different methods. First, immunoprecipitation experiments, using isoenzyme-specific monoclonal Lox antibodies, showed that 14-3-3 proteins co-precipitate with 13-Lox, but not with the 9-Lox from barley. Second, interactions between 13-Lox and 14-3-3 were...

Recently, we have demonstrated by two different methods that lipoxgenases (LOXs) and 14-3-3 proteins form interactions in barley embryos [Holtman, Roberts, Oppedijk, Testerink, van Zeijl and Wang (2000) FEBS Lett. 474, 48-52]. It was shown by both co-immunoprecipitations and surface-plasmon resonance experiments that 13-LOX, but not 9-LOX, forms...

Expression and post-translational modification of barley 14-3-3 isoforms, 14-3-3A, 14-3-3B and 14-3-3C, were investigated using isoform-specific antibodies. Although all three isoforms were shown to be present in the cytosolic, the nuclear and the microsomal cell fractions, differences in post-translational modification were identified for the...

Two full-length lipoxygenase cDNA sequences (LoxB and LoxC) from barley (Hordeum distichum cv. L. Triumph) are described. The cDNAs share high homology with the barley LoxA cDNA. Southern blotting experiments indicate single copy numbers of the three lipoxygenase genes. RFLP mapping revealed the presence of single lipoxygenase loci. LoxA and...

The barley lipoxygenase 1 (Lox1) gene encodes a protein expressed in embryos during grain development and germination and in leaves after methyl-jasmonate (MeJA) treatment. Transient gene expression assays in germinating barley embryos were used to identify cis-regulatory elements involved in the embryo-specific expression of the Lox1 gene....

Besides the pre-existing lipoxygenase (LOX-1) present in quiescent grains, a new lipoxygenase (LOX-2) is induced in embryos of germinating barley [Holtman, W. L., Van Duijn, G., Sedee, N. J. A. and Douma, A. C. (1996) Plant Physiol. 111, 569-576]. The fact that LOX-1 and LOX-2 form different products after incubation with linoleic acid, the (9S)...
