Changes in expansin activity and gene expression during ethylene-promoted leaflet abscission in Sambucus nigra.
During ethylene-promoted leaflet abscission in Sambucus nigra a 7-fold increase in expansin activity was detected specifically in tissues undergoing cell separation, whilst only low levels of activity were seen in adjacent non-abscising tissues. An RT-PCR strategy was used to amplify expansin fragments from a cDNA library generated from mRNA extracted from ethylene-treated leaflet abscission-zo...
متن کاملSambucus nigra (Elderberry) Monograph
Introduction Sambucus nigra, or European elder, is a tall tree-like shrub, native to Europe, Asia, and North Africa, and naturalized in the United States. Various parts of the elder have long been used in traditional medicine as a diaphoretic, diuretic, astringent, laxative, and emetic. The berries were used traditionally as a food to make elderberry wine and pies, and as a flavoring or dye. Cu...
متن کاملEthylene-induced differential gene expression during abscission of citrus leaves
The main objective of this work was to identify and classify genes involved in the process of leaf abscission in Clementina de Nules (Citrus clementina Hort. Ex Tan.). A 7 K unigene citrus cDNA microarray containing 12 K spots was used to characterize the transcriptome of the ethylene-induced abscission process in laminar abscission zone-enriched tissues and the petiole of debladed leaf explant...
متن کاملAntidepressant activities of Sambucus ebulus and Sambucus nigra.
OBJECTIVE Many pharmacological activities have been reported in Sambucus (S.) genus. The aim of present study was to investigate antidepressant activities of different parts of S. ebulus and S. nigra. MATERIALS AND METHODS Antidepressant activity of methanolic extracts were evaluated by forced swimming test (FST) and tail suspension tests (TST) in male Swiss albino mice. RESULTS Extracts sh...
متن کاملIsolation, Subtype Determination, Cloning and Expression of HBsAg Gene from an Iranian Carrier in Saccharomyces cerevisiae
The Hepatitis B Surface antigen ( HBsAg) gene was isolated from an Iranian HBeAg positive carrier by PCR. The gene was cloned in pUC19 for sequencing and pYES2 for expression in Saccharomyces cerevisiae, which pNF1 and pDF3 constructs were made respectively. The sequencing data showed that the isolated HBsAg gene shared more than 90% homology with the ayw subtype. The pDF3 was transferred into ...
