Condensed lignins are synthesized in poplar leaves exposed to ozone.
Poplar (Populus tremula x alba) trees (clone INRA 717-1-B4) were cultivated for 1 month in phytotronic chambers with two different levels of ozone (60 and 120 nL L(-1)). Foliar activities of shikimate dehydrogenase (EC 1.1.1.25), phenylalanine ammonia lyase (EC 4.3.1.5), and cinnamyl alcohol dehydrogenase (CAD, EC 1.1.1.195) were compared with control levels. In addition, we examined lignin con...

15 صفحه اولComparative Study of some Characteristics in Leaves and Roots of two Canola Genotypes under Lead Stress
The effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (Brassica napus L.) grown in the Hoagland solution. The growth of treated plants was inhibited under lead stress. Lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgL-1 of Pb. Hyola308 cultivar showed low biomass...
متن کاملDifferential gene expression in senescing leaves of two silver birch genotypes in response to elevated CO2 and tropospheric ozone.
Long-term effects of elevated CO(2) and O(3) concentrations on gene expression in silver birch (Betula pendula Roth) leaves were studied during the end of the growing season. Two birch genotypes, clones 4 and 80, with different ozone growth responses, were exposed to 2x ambient CO(2) and/or O(3) in open-top chambers (OTCs). Microarray analyses were performed after 2 years of exposure, and the t...
متن کاملS-Nitroso-Proteome in Poplar Leaves in Response to Acute Ozone Stress
Protein S-nitrosylation, the covalent binding of nitric oxide (NO) to protein cysteine residues, is one of the main mechanisms of NO signaling in plant and animal cells. Using a combination of the biotin switch assay and label-free LC-MS/MS analysis, we revealed the S-nitroso-proteome of the woody model plant Populus x canescens. Under normal conditions, constitutively S-nitrosylated proteins i...
