Selectable Markers and Promoters for Environmentally Friendly Plant Tissue Culture Transformation
Detailed Technology Description
This DNA-based technology provides a novel, selectable marker gene and promoter for producing transgenic plants with heightened levels of tryptophan (Trp). Specifically, it includes a tobacco-derived gene for a variant of the enzyme anthranilate synthase (AS). This technology encompasses the gene (ASA2) and its promoter, and is capable of directing tissue culture-specific transcription of a downstream structural gene in plant cells. Relevant methods and transformed, regenerated plants are included in the technology.
