The present disclosure provides methods for increasing drought resistance, salt resistance, and biomass production of a plant. The methods encompass expression of DiGeorge-Syndrome Critical Region 14 (DGCR14) gene in the plant. In comparison to a plant not manipulated in this manner, the disclosed, genetically-modified, plants display improved drought resistance and salt 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.

Methods of improving drought and salt resistance in a plant and genetically engineered plants with improved drought and salt resistance

This disclosure provides genetically modified plants, plant cells and plant tissues that show modified lignin content and/or sugar release as compared to a wild type control plant which was not genetically modified. In addition, the disclosure provides methods of regulating lignin content and sugar release in a plant. The disclosure also provides methods of producing bioproducts using the genetically modified plants of the instant disclosure.

Regulating lignin biosynthesis and sugar release in plants

The present disclosure provides genetically modified plants, plant cells and plant tissues that show reduced lignin content as compared to a control plant which was not genetically modified. In addition, the disclosure provides methods of regulating lignin content in a plant. The disclosure also provides methods of producing bioproducts using the genetically modified plants of the instant disclosure.

Loss of function alleles of PtEPSP-TF and its regulatory targets in rice

This disclosure provides methods of improving callus formation in plants. This disclosure further provides genetically engineered plants with improved callus formation.

Methods for improving callus formation and regeneration in plants

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.

Genes for enhancing drought and heat tolerance in plants and methods of use

The present disclosure is directed to methods of improving mycorrhization in a plant or plant cell. Another aspect of this disclosure is directed to a genetically modified plant or plant cell with improved mycorrhization.

Methods of improving mycorrhization in plants and genetically modifed plants with improved mycorrhization

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, encoded by locus Potri.008G064000 resulted in transgenictrees 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.

Modulating laccase enzyme to regulate cell wall biosynthesis and recalcitrance in plants

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, encoded by locus Potri.011G009500 resulted in transgenictrees 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.
