TRANSGENIC PLANT OSEENS VERSATILE BY PRODUCTIVITY AND BY MODIFIED WOOD

摘要

1. A transgenic plant with increased productivity aspen and the modified timber and its progeny of sexual and / or asexual, resulting unique transformation act between a nucleic acid molecule encoding glutamine synthetase, and genomic DNA osiny.2. The transgenic plant according to claim 1, wherein the nucleic acid molecule is a cDNA molecule isolated from Scots pine (Pinus sylvestris L.), having the nucleotide sequence shown in SEQ ID N0:. 1.3. The transgenic plant according to claim. 1, where aspen is the representative species Populus tremula L.4. The transgenic plant according to claim 1, which exhibits one or more of the following signs of increased productivity, but not limited to:. An increased growth rate, increased biomass yield, larger leaves and increased activity of glutamine synthetase, increased nitrogen use efficiency as compared to the wild type counterpart. 5. The transgenic plant according to claim 1, which exhibits one or more of the following features wood modification, but not limited to:. Altered lignin content, altered cellulose content, modified hemicellulose content, a modified structure of lignin, modified parameters wood fibers as compared with an analogue wildtype. 6. A method for producing a transgenic plant aspen according to claim 1 comprising:.. A) Agrobacterium-mediated transformation of explants of aspen in vitro a nucleic acid molecule having the nucleotide sequence of claim 2, and b) regeneration of plants from transformed explants cells, c) identifying the nucleic acid molecule encoding a glutamine synthetase
