  • Publication number: 20120034658
    Abstract: Disclosed are methods for obtaining blue anthocyanin pigments and compositions including such pigments. This blue anthocyanin is present at an acidic pH (where anthocyanins are most stable) and may be used as a natural color additive. The methods can include cultivating a plant callus from a plant capable of producing anthocyanin in which the callus is treated with a blue anthocyanin-generating agent at a concentration sufficient to generate callus with blue anthocyanin pigments. The method can also include recovering the blue anthocyanin pigments from the culture. In an example, the blue anthocyanin-generating agent is ammonium molybdate.

  • Publication number: 20050203033
    Abstract: Flavonoids are obtained from plants that overexpress an ANT1 gene compared to wild-type plants. The plant may be a transgenic plant that contains a transformation vector that causes the overexpression of ANT1. Alternatively, the plant can be selectively bred to have an allele of or mutation in an endogenous ANT1 gene that causes the overexpression of ANT1 compared to plants lacking the allele or mutation.

  • Publication number: 20020157130
    Abstract: The present invention provides a method for identifying and characterizing genes, the modified expression of which is associated with a desired trait in a fruit-bearing plant. The method includes the steps of: transforming plant cells with a plant cell expression vector comprising an element which functions to enhance gene expression and has the ability to integrate into the plant genome in a manner effective to enhance expression of native plant genes, selecting transformed plant cells, regenerating transformed plant cells to yield mature plants, selecting plants having a desired trait, identifying, isolating and characterizing genes the transcription of which has been enhanced and confirming the contribution of the modified expression of each identified gene to the desired trait.
