Described herein are plants, plant seeds, and plants cells that are modified to express particular types of cellulose synthase enzymes (but not CesA3, CesA9, or CesA7 enzymes). Such plants, plant seeds and plant cells can be cotton, flax, hemp, jute, sisal, poplar, or eucalyptus plants, plant seeds or plant cells. The modified plants tend to grow taller, have increased cellulose synthesis, have more crystalline cellulose, have wider secondary cell walls, increased biomass, and increased mechanical strength than in a control plant without the expression cassette (e.g., a wild type or parental plant without the expression cassette).

The invention relates to nucleic acids, proteins and methods for modulating the cellulose content of plants.

Methods and materials for modulating biomass composition in plants are disclosed. For example, nucleic acids encoding biomass composition-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having altered biomass composition and plant products produced from plants having altered biomass composition.

Provided are isolated polynucleotides encoding a polypeptide at least 80% homologous to the amino acid sequence selected from the group consisting of SEQ ID NOs: 757, 456-756, 758-774, 8385-10836, and 10838-14462; and isolated polynucleotide comprising nucleic acid sequences at least 80% identical to SEQ ID NO: 377, 1-376, 378-455, and 775-8384. Also provided are nucleic acid constructs comprising same, isolated polypeptides encoded thereby, transgenic cells and transgenic plants comprising same and methods of using same for increasing yield, biomass, growth rate, vigor, oil content, fiber yield, fiber quality, abiotic stress tolerance, and/or nitrogen use efficiency of a plant.

The present invention relates to isolated polypeptides having cellulolytic enhancing activity, catalytic domains, cellulose binding domains and polynucleotides encoding the polypeptides, catalytic domains or cellulose binding domains. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides, catalytic domains or cellulose binding domains.

The present invention provides methods and compositions for targeting enzymes involved in lignin or xylan biosynthesis using genome editing nucleases to specifically reduce content in a desired plant cell type(s).

The present invention relates to a hetero-transglycosylase protein having cellulose:xyloglucan endotransglucosylase (CXE) activity in addition to mixed-linkage beta-glucan:xyloglucan endotransglucosylase (MXE) activity. The protein may comprise the amino acid sequence of any one of SEQ ID NOs: 2, 6 and 8 or a functional fragment thereof; or an amino acid sequence having at least 60% sequence identity to any one of SEQ ID NO: 2, 6 and 8, or to SEQ ID NO: 2 from amino acid 22 to 280, to SEQ ID NO: 6 from amino acid 26 to 283, or to SEQ ID NO: 8 from amino acid 29 to 287. The invention furthermore relates to an isolated nucleic acid encoding the protein described herein, a chimeric gene comprising, inter alia, the nucleic acid described herein, a vector comprising said chimeric gene, a host cell comprising said vector or said chimeric gene and an according transgenic plant. Further disclosed herein in are a method of producing a transgenic plant and a method of improving properties of cellulosic material.

Described herein are devices and methods for increasing the production of steviol glycosides, which have industrial and economic value. The steviol glycosides produced by the devices and methods disclosed herein do not require the ultra purification that is common in conventional or commercial methods and do not have a bitter aftertaste, making them better suited as flavor-enhancing N additives to food, pharmaceutical, and nutritional supplement products.

The present invention relates to isolated polypeptides having beta-xylosidase activity and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.
