摘要:
Materials and methods are provided for identifying regulatory region-regulatory protein associations and modulating expression of a sequence of interest. For example, a plant cell is provided containing a regulatory protein that can modulate expression of one or more genes involved in alkaloid biosynthesis in plants, which, in turn, can modulate the amount and/or rate of biosynthesis of one or more alkaloid compounds.
摘要:
The present invention is directed to promoter sequences and promoter control elements, polynucleotide constructs comprising the promoters and control elements, and methods of identifying the promoters, control elements, or fragments thereof. The invention further relates to the use of the present promoters or promoter control elements to modulate transcript levels.
摘要:
Disclosed are novel transgenic plant cells that include a heterologous (e.g., human) receptor polypeptide, or fragment thereof. The plant cells can be used to identify molecules (i.e., ligands) that can interact with the receptor polypeptide or fragment. The plant cells can be used to identify ligands that are endogenous to transgenic plant cells, or exogenous ligands that are applied to the plant cells. Such receptor polypeptide ligands can be used to identify novel pharmaceuticals.
摘要:
Materials and Methods for identifying lignin regulatory region-regulatory protein associations are disclosed. Materials and methods for modulating lignin accumulation are also disclosed. In addition, methods and materials for modulating (e.g., increasing or decreasing) the level of a component (e.g., protein, oil, lignin, carbon, a carotenoid, or a triterpenoid) in plants are disclosed.
摘要:
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.
摘要:
The present invention provides DNA molecules that constitute fragments of the genome of a plant, and polypeptides encoded thereby. The DNA molecules are useful for specifying a gene product in cells, either as a promoter or as a protein coding sequence or as an UTR or as a 3′ termination sequence, and are also useful in controlling the behavior of a gene in the chromosome, in controlling the expression of a gene or as tools for genetic mapping, recognizing or isolating identical or related DNA fragments, or identification of a particular individual organism, or for clustering of a group of organisms with a common trait. One of ordinary skill in the art, having this data, can obtain cloned DNA fragments, synthetic DNA fragments or polypeptides constituting desired sequences by recombinant methodology known in the art or described herein.
摘要:
Materials and methods for modulating (e.g., increasing or decreasing) lignin content in plants are disclosed. For example, nucleic acids encoding lignin-modulating polypeptides are disclosed as well as methods for using such nucleic acids to generate transgenic plants having a modulated lignin content.
摘要:
Materials and methods for identifying terpenoid regulatory region-regulatory protein associations are disclosed. Materials and methods for modulating expression of a sequence interest are also disclosed.
