15 صفحه اولGibberellic Acid Regulates Chalcone Synthase Gene Transcription in the Corolla of Petunia hybrida.
The pigmentation of Petunia hybrida corollas is regulated by gibberellic acid (GA(3)). It controls the increase of flavonoid enzyme levels and their corresponding mRNAs. We have used an in vitro culture system for corollas to study the regulatory role of GA(3) in the expression of flavonoid genes. By determining steady-state mRNA levels, we show that the accumulation of chalcone synthase (chs) ...
متن کاملCharacterization of the Flavonoids from Petunia ×hybrida Flowers Expressing the A1 Gene of Zea mays
The flavonoids from flowers of transgenic Petunia ×hybrida Vilm. plants containing the Al gene from Zea mays L. were characterized. The A1 gene encodes the enzyme dihydroflavonol reductase and was introduced into a mutant petunia defective for this gene. Control, nontransgenic plants produced flowers that contained ≈ 50 ng anthocyanin/ 100 mg tissue dry weight. Anthocyanin distribution was 63% ...
متن کاملThe S-Ribonuclease Gene of Petunia hybrida
To determine the ability of isolated S-locus promoter sequences to direct organ-specific gene expression, we used microprojectile bombardment to introduce chimeric S-allele/&glucuronidase genes into different tissues of Petunia hybrida for transient expression. Histochemical staining showed that S-locus/B-glucuronidase fusions were expressed in pistil, ovary, and petal tissue. No expression of ...
