DiFazio and Richard Meilan Poplars (genus Populus) have emerged as a model organism for forest biotechnology, and genetic modification (GM: asexual gene transfer) is more advanced for this genus than for any other tree. The goal of this paper is to consider the benefits expected from the use of GM poplar trees, and the most significant claims made for environmen...

chlorinated biphenyl (PC8I mixtures had been described previously. High mortality, liver damage, and edema were associated with only two of the three PCB5. Using column and gas chromatography, several compounds were identified in the diethylether fracdon of these two PCBs. A chick embryo assay confirmed the high toxicity of this fraction. Mass spectremetric and microcoulometric analyses indicat...
متن کاملBarcoding Poplars (Populus L.) from Western China
BACKGROUND Populus is an ecologically and economically important genus of trees, but distinguishing between wild species is relatively difficult due to extensive interspecific hybridization and introgression, and the high level of intraspecific morphological variation. The DNA barcoding approach is a potential solution to this problem. METHODOLOGY/PRINCIPAL FINDINGS Here, we tested the discri...
