Abstract
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).
Claims13
A transgenic plant, plant seed, or plant cell comprising an expression cassette comprising a promoter operably linked to a nucleic acid segment encoding a CesA protein with at least 95% sequence identity to any of SEQ ID NO:
- 3, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, or 16, wherein the plant has a longer mean fiber length of fibers in hypocotyls, roots, stems, or cotton bolls than control plants.
A method comprising cultivating a seed or plant comprising an expression cassette comprising a promoter operably linked to a nucleic acid segment encoding a CesA protein with at least 95% sequence identity to any of SEQ ID NO:
- 3, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, or 16 and harvesting biomass or fiber from the plant or from a plant grown from the seed.
