Isolation and bacterial expression of a sesquiterpene synthase cDNA clone from peppermint (Mentha x piperita, L.) that produces the aphid alarm pheromone (E)-b-farnesene (insect pheromoneyplant-insect chemical communicationysynomone)
E)-b-Farnesene is a sesquiterpene semiochemical that is used extensively by both plants and insects for communication. This acyclic olefin is found in the essential oil of peppermint (Mentha x piperita) and can be synthesized from farnesyl diphosphate by a cell-free extract of peppermint secretory gland cells. A cDNA from peppermint encoding (E)-b-farnesene synthase was cloned by random sequenc...
متن کاملMercuric ion reduction and resistance in transgenic Arabidopsis thaliana plants expressing a modified bacterial merA gene.
With global heavy metal contamination increasing, plants that can process heavy metals might provide efficient and ecologically sound approaches to sequestration and removal. Mercuric ion reductase, MerA, converts toxic Hg2+ to the less toxic, relatively inert metallic mercury (Hg0) The bacterial merA sequence is rich in CpG dinucleotides and has a highly skewed codon usage, both of which are p...
متن کاملAlarm pheromone habituation in Myzus persicae has fitness consequences and causes extensive gene expression changes.
In most aphid species, facultative parthenogenetic reproduction allows rapid growth and formation of large single-genotype colonies. Upon predator attack, individual aphids emit an alarm pheromone to warn the colony of this danger. (E)-beta-farnesene (EBF) is the predominant constituent of the alarm pheromone in Myzus persicae (green peach aphid) and many other aphid species. Continuous exposur...
متن کاملThe impacts of TRR14 over-expression on Arabidopsis thaliana growth and some photosynthetic parameters
Background: TRR14 protein is a small member of a multi-gene family in Arabidopsis and is the first ones found during screening of seedlings for their resistant to the trehalose sugar.Objectives: Characterization ofTRR14 over-expressed plants with respect to morphological changes, growth and photosynthesis related parameters.Materials and methods: TRR14gene was isolated from Arabidop...
متن کاملExpression and developmental function of the 3-ketoacyl-ACP synthase2 gene in Arabidopsis thaliana.
The 3-ketoacyl-ACP synthase (KAS) II is a fatty-acid-related enzyme which catalyzes the elongation of 16:0-acyl carrier protein (ACP) to 18:0-ACP in plastids. The fatty acid biosynthesis 1-1 (fab1-1) mutant of Arabidopsis thaliana is partially deficient in its activity of Arabidopsis thaliana 3-ketoacyl-ACP synthase 2 (AtKAS2), and its phenotype has been intensively studied in connection with t...
