Aminocyclopropane Carboxylic Acid Synthase Is a Regulated Step in Ethylene-Dependent Induced Conifer Defense. Full-Length cDNA Cloning of a Multigene Family, Differential Constitutive, and Wound- and Insect-Induced Expression, and Cellular and Subcellular Localization in Spruce and Douglas Fir12[W][OA]
In conifer stems, formation of chemical defenses against insects or pathogens involves specialized anatomical structures of the phloem and xylem. Oleoresin terpenoids are formed in resin duct epithelial cells and phenolics accumulate in polyphenolic parenchyma cells. Ethylene signaling has been implicated in the induction of these chemical defenses. Recently, we reported the cloning of 1-aminoc...
متن کاملDifferential Regulation of Genes Encoding Ethylene Biosynthesis Enzymes and Ethylene Response Sensor Ortholog during Ripening and in Response to Wounding in Avocados
We investigated the differential regulation of two 1-aminocyclopropane-1-carboxylate synthase (ACS) genes, one 1-aminocyclopropane-1-carboxylate oxidase (ACO) gene and one ethylene response sensor (ERS1) ortholog during ripening and in response to wounding in avocados (Persea americana Mill. ‘Bacon’). The 1-aminocyclopropane-1carboxylate (ACC) content, ACS activity and detectable expression of ...
متن کاملMolecular characterization of a transient expression gene encoding for 1-aminocyclopropane-1-carboxylate synthase in cotton (Gossypium hirsutum L.).
Ethylene performs an important function in plant growth and development. 1-aminocyclopropane-1-carboxylate (ACC) synthase (ACS), the key enzyme involved in ethylene biosynthesis, has been the focus of most ethylene studies. Here, a cotton ACS gene referred to as Gossypium hirsutum ACS1 (GhACS1), was isolated. The full-length cDNA of GhACS1 encodes for a 476-amino acid protein which harbors seve...
متن کاملP-121: Cloning and Expression of The Inosine Triphosphate Pyrophosphatase Gene Variant II in E.coli
Background Environmental and cellular inappropriate conditions can cause damages to cells nucleotide poll. Deamination and oxidation damages interfere with cell�s vital reactions. Inosine triphosphate pyrophosphatase (ITPA), an evolutionary conserved enzyme, plays a critical role in elimination of non-canonical bases. In human genome, the ITPA gene is located on chromosome 20 short arm and tran...
متن کاملExpression of hsp90 Alpha and hsp90 Beta during Xenopus laevis Embryonic Development
Background: Members of the eukaryotic Hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. Two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. In the present study, the expression of hsp90 alpha and hsp90 beta genes in Xenopus...
