  • TRANSGENIC PLANTS HAVING INCREASED BIOMASS
    Publication number: 20130014292
    Abstract: Methods and materials for modulating biomass levels in plants are disclosed. For example, nucleic acids encoding biomass-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased biomass levels and plant products produced from plants having increased biomass levels.

  • Methods for modifying plant characteristics
    Patent number: 7897839
    Abstract: Isolated polynucleotides, polypeptides, and transgenic plants are described. The transgenic plants can exhibit one or more altered phenotypic characteristics relative to a control plant, including increased height, increased seed weight, increased photosynthetic rates, decreased levels of campestanol, or increased levels of 6-deoxocathasterone.

  • Chimeric polypeptides
    Patent number: 6977293
    Abstract: A new class of chimeric polypeptides is disclosed that includes a transmembrane segment, an intracellular reporting segment, and an extracellular sorting segment. The novel polypeptides can be used to detect gene expression at the cellular level, and to isolate precisely those cells that are detected from organisms, organs, tissues, and mixtures of cells.
