WOODY PLANTS HAVING IMPROVED GROWTH CHARACTERISTICS AND METHOD FOR MAKING THE SAME USING TRANSCRIPTION FACTORS

摘要

An extensive analytical platform for selecting genes with a possible commercial phenotype from a large group of candidate genes identified using tools in bioinformatics, data from EST sequencing and DNA array is disclosed. Methods are disclosed for producing a transgenic plant having an increased growth compared to its wild type by altering in the plant the level of a gene product of at least one gene specifically expressed during different phases of wood formation. This may be done with transgenic methods or by specific crossing methods. Plant cells or plant progeny and wood having modulated gene expression are also disclosed. A DNA construct with a nucleotide sequence for a gene producing a transgenic plant having an increased growth compared to its wild type and a plant cell or plant progeny having the DNA construct are also disclosed.

主权项

1. A method of producing a tree having a modulated growth and/or biomass compared to its wild type, said method comprising transforming said tree with a nucleic acid comprising a promoter operably linked to a polynucleotide encoding a functional gene product comprising a polypeptide sequence selected from the group consisting of SEQ ID NO: 14-23, 25, 26, and 116-134, and variants thereof comprising a conservative substitution, wherein an increased level of the functional gene product results in a modulated growth and/or biomass in said tree.
