摘要： Disclosed are methods for obtaining a natural product preparation with reduced glucosinolate contamination from a plant of Brassicaceae. The methods can include cultivating a plant callus from a plant capable of producing a desired natural product, selecting a callus with reduced glucosinolate production, and cultivating the selected callus in a liquid medium. The method can also include recovering the natural product from the culture. Also disclosed are methods for obtaining cabbage anthocyanin with reduced glucosinolate contamination. The methods can include cultivating a red cabbage plant callus with reduced glucosinolate production in a liquid medium to obtain a suspension culture and cultivating the suspension culture in a medium lacking a nitrogen source. The method can also include recovering the anthocyanin with reduced glucosinolate contamination from the culture. Finally, several specific low-glucosinolate cell lines are described.

摘要： 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.

摘要： The present invention is directed to the identification and isolation of a promoter region from a raspberry genome. The promoter is operably linked, in a native raspberry genome, to the coding region of a raspberry E4 gene. The raspberry E4 gene promoter of the invention is capable of regulating moderate level, constitutive expression of a heterologous plant gene under its control. The invention is further directed to chimeric genes, cassette vectors, kits, transgenic plants, and methods employing a raspberry E4 promoter.

摘要： 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.
