Responses of Populus deltoides × Populus nigra ( Populus × euramericana ) clone I - 214 to high zinc concentrations
• We hypothesized that poplar can be useful for the extraction of zinc (Zn) from contaminated soils and water. However, the physiological response and the base of tolerance of poplar plants to this heavy metal are little known. • Plants of Populus deltoides × P . nigra ( P. × euramericana ) I-214 clone were grown in glasshouse and treated with three different Zn concentrations (1, 100 and 1000 ...
متن کاملRunning title: Multi-locus polymorphism in Populus tremula Keywords: demography, linkage disequilibrium, nucleotide polymorphism, Populus tremula Multilocus patterns of nucleotide polymorphism and the demographic history of Populus tremula
I have studied nucleotide polymorphism and linkage disequilibrium using multilocus data from 77 fragments, with an average length of fragments 550 bp, in the deciduous tree Populus tremula (Salicaceae). The frequency spectrum across loci showed a modest excess of mutations segregating at low frequency and a marked excess of high frequency derived mutations at silent sites, relative to neutral e...
متن کاملGenetic Modification of Lignin in Hybrid Poplar (Populus alba × Populus tremula) Does Not Substantially Alter Plant Defense or Arthropod Communities
Lignin impedes access to cellulose during biofuel production and pulping but trees can be genetically modified to improve processing efficiency. Modification of lignin may have nontarget effects on mechanical and chemical resistance and subsequent arthropod community responses with respect to pest susceptibility and arthropod biodiversity. We quantified foliar mechanical and chemical resistance...
متن کاملChemical responses to modified lignin composition in tension wood of hybrid poplar (Populus tremula x Populus alba).
The effect of altering the expression level of the F5H gene was investigated in three wood tissues (normal, opposite and tension wood) in 1-year-old hybrid poplar clone 717 (Populus tremula × Populus alba L.), containing the F5H gene under the control of the C4H promoter. Elevated expression of the F5H gene in poplar has been previously reported to increase the percent syringyl content of ligni...
متن کاملGC-MS analysis of compounds extracted from buds of Populus balsamifera and Populus nigra.
The composition of hexane and ether extracts from buds of two poplar species (Populus balsamifera and P. nigra) was investigated by GC-MS method. In hexane extracts, 54 "neutral" compounds were recorded. The greatest amounts of them are sesquiterpenes and n-alkanes. Among 56 components of ether extracts, many aliphatic acids and hydroxyacids were detected. However, the main fraction consists of...
