  • Patent number: 11041164
    Abstract: The present disclosure provides methods for increasing drought resistance and heat resistance of a plant. The methods encompass expression of at least one heat shock protein (HSP) from the group consisting of HSP40, HSP60 or HSP70 together with a phosphoenolpyruvate carboxylase (PEPC) comprising an aspartic acid (D) at a position that corresponds to the position 509 of SEQ ID NO: 4, in the plant. In comparison to a plant not manipulated in this manner, the disclosed, genetically-modified, plants display improved drought resistance and heat resistance. Also provided are plants that can be obtained by the method according to the invention, and nucleic acid vectors to be used in the described methods.

  • Patent number: 10246719
    Abstract: This disclosure provides genetically modified plants having desirable levels of sugar release and syringyl/guaiacyl (S/G) ratio; methods of genetically modifying plants to modulate sugar release and S/G ratio; and uses of such plants. The inventors have determined that genetic modification of a laccase gene (LAC2) from Populus, encoded by locus Potri.008G064000 resulted in transgenic Populus trees with changes in syringyl/guaiacyl ratios as well as altered sugar release phenotypes. Plants with altered sugar release, and S/G ratio, based on modulation of the expression or activity of the LAC2 gene, have divergent uses including pulp and paper production, and biofuel and bioproducts production.

  • Patent number: 10227601
    Abstract: This disclosure provides genetically modified plants having desirable levels of sugar release, cellulose content and reduction of recalcitrance; methods of genetically modifying plants to modulate sugar release, cellulose and lignin contents; and uses of such plants. The inventors have determined that genetic modification of PdDUF266A from Populus, encoded by locus Potri.011G009500 resulted in transgenic Populus trees with changes in lignin and cellulose content as well as altered sugar release phenotypes. Plants with altered sugar release, cellulose and lignin content, based on modulation of the expression or activity of the PdDUF266A gene, have diverse uses including pulp and paper production, and biofuel and bioproducts production.

  • Publication number: 20040187176
    Abstract: The invention provides methods for improving plant agronomic traits by altering the expression or activity of plant G-protein alpha and beta subunits that are GPA1 or AGB1 orthologs. The invention also provides such transgenic plants with improved agronomic traits. One embodiment of the invention includes methods for modulating the expression or activity of a plant G-protein beta subunit that is an AGB1 ortholog to alter one or more of the following: the time to reach and duration of flowering, fruit yield, root biomass, seed size, seed shape, plant size, and the number of stem branches. The present invention also encompasses methods for modulating the expression or activity of a plant G-protein alpha subunit that is a GPA1 ortholog to alter one or more of the following: the duration of flowering, fruit and seed yield, plant size, seed size, and seed shape.
