Woody plants having improved growth characteristics and method for making the same using transcription factors

摘要

The present invention pertains to a novel and 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. An aspect of the invention provides methods of producing a transgenic plant having an increased growth compared to its wild type. The method comprises 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. Further aspects of the invention provide a plant cell or plant progeny and wood having modulated gene expression according to the invention. Other aspects pertain a DNA construct comprising a nucleotide sequence of the invention and a plant cell or plant progeny comprising the DNA construct.

主权项

1. A method of producing a tree having an increased 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 having at least 95% sequence identity to SEQ ID NO: 24, wherein said increased level of the functional gene product results in an increase in growth and/or biomass in said tree.
