daucus glaber/proline

The effect of tryptophan on the biosynthesis of proline has been investigated. Cells of Daucus carota grown in B5 medium supplemented with 5×10(-4)M tryptophan acquired the ability to grow in the presence of inhibitory concentrations of azetidine-2-carboxylic acid, an analog of proline. When trp was

The E1 promoter fragment (-249 to -203) is one of three auxin-response elements (AuxREs) in the soybean (Glycine max L.) GH3 promoter (Z.-B. Liu, T. Ulmasov, X. Shi, G. Hagen, T.J. Guilfoyle [1994] Plant Cell 6: 645-657). Results presented here further characterize and delimit the AuxRE within the

A novel, highly hydrophobic, glycine- and proline-rich peptide was characterized in the ovary of the desert locust, Schistocerca gregaria. The peptide was detected as one of the major peaks in a chromatographic separation of an acidic methanolic extract of 50 mature ovaries. Electrospray mass

The effect of proline analogs on peptidyl proline hydroxylation has been studied in vivo using aerated root slices of Daucus carota. One analog, 3,4-dehydroproline, acted at micromolar concentrations to rapidly and selectively inhibit peptidyl proline hydroxylation. A structurally altered

Serine and proline, when added in a wide range of concentrations to Daucus carota cultures during pre-growth in the presence of 2,4-D(2,4-dichlorophenoxyacetic acid), extended in time and quantity the mitotic divisions and stimulated significantly the number of embryos regenerated when the hormone

Arabinogalactan proteins (AGPs) are secreted or membrane-associated glycoproteins that have been operationally defined as binding to [beta]-glucosyl Yariv artificial antigen, being rich in arabinose and galactose, and containing high levels of alanine, serine, and hydroxyproline. Using an anti-AGP

The application of triazole fungicides is a common practice in the cultivation of carrot (Daucus carota L.) plants. It is there for seems important to test the changes that are occurring in this food crop under triazoles, the non-traditional plant growth regulators, treatments in order to identify

Five clones were isolated from five different amino acid analog-resistant Daucus carota L. var. Sativa and Nicotiana tabacum L. cv. Xanthi cell lines. The individual clones were similar in their resistance to dl-5-methyltryptophan, S-(2-aminoethyl)-l-cysteine, or azetidine-2-carboxylic acid, and in

A carrot (Daucus carota, L.) genomic clone (DcPRP1) was isolated on the basis of its homology to previously described cDNAs encoding a wound-inducible, proline-rich cell wall protein. DNA sequence analysis showed that DcPRP1 contains a single open-reading frame encoding a 235-amino acid protein that

Pulse labeling of carrot root phloem parenchyma (Daucus carota L. cv. Nantes) tissue with (14)C-proline followed by fractionation of the cytoplasmic organelles on sucrose gradients was used to determine the identity of the membranous organelles involved in the secretion of the hydroxyproline-rich

When disks of carrot (Daucus carota) phloem parenchyma are incubated for 6 days there is a 10-fold increase in cell wall hydroxyproline due to the synthesis and secretion of hydroxyproline-containing macromolecules. The synthesis of these molecules and their secretion are demonstrated by measuring

Data base (NCBI and TIGR) searches are made to retrieve protein sequences of different plant species namely Medicago truncatula, Pisum sativum, Ricinus communis, Arabidopsis thaliana, Vitis vinifera, Glycine max, Daucus carota, Oryza sativa Japonica Group, Arabidopsis lyrata subsp. lyrata,

Antiserum was raised against a synthetic nona-peptide which was predicted to have considerable homology with the unhydroxylated, unglycosylated precursor of cell wall proteins from several plants. The antiserum is able to recognize the major cell wall protein of incubated carrot (Daucus carota) root

A single glycoprotein accounts for the majority of radioactivity secreted to the cell wall when incubated carrot (Daucus carota) discs are labeled with radioactive proline or arabinose. The ferrous chelator alpha,alpha'-dipyridyl prevents the synthesis of this protein. A new proline-labeled protein

Suspension-cultured cell lines from plant species are useful for genetic engineering. However, maintenance of these lines is laborious, involves routine subculturing and hampers wider use of transgenic lines, especially when many lines are required for a high-throughput functional genomics
