We attempted to overexpress chalcone synthase (CHS) in pigmented petunia petals by introducing a chimeric petunia CHS gene. Unexpectedly, the introduced gene created a block in anthocyanin biosynthesis. Forty-two percent of plants with the introduced CHS gene produced totally white flowers and/or patterned flowers with white or pale nonclonal sectors on a wild-type pigmented background; none of hundreds of transgenic control plants exhibited such phenotypes. Progeny testing of one plant…

Cosuppression of Tobacco Chalcone Synthase Using Petunia Chalcone Synthase Constructs Results in White Flowers

Results indicate that cosuppression of the tobacco chs gene can occur using the equivalent Petunia gene, and demonstrate a linkage between the expression level of chs mRNA, cyanidin content, and flower color in transgenic tobacco plants.

Flavonoid genes in petunia: addition of a limited number of gene copies may lead to a suppression of gene expression.

The similarity between the sense transformants and regulatory CHS mutants suggests that this mechanism of gene silencing may operate in naturally occurring regulatory circuits.

Post-transcriptional silencing of chalcone synthase in petunia using a geminivirus-based episomal vector.

In white-spotted flower tissue, steady-state ChsA mRNA levels were downregulated but rates of RNA transcription were unaffected, suggesting that the phenotype resulted from post-transcriptional gene silencing of the endogenous and episomal ChSA genes.

Chalcone synthase as a reporter in virus-induced gene silencing studies of flower senescence

The results indicate the value of VIGS with tandem constructs containing CHS as reporter and a target gene as a tool for examining the function of floral-associated genes.

Tandemly arranged chalcone synthase A genes contribute to the spatially regulated expression of siRNA and the natural bicolor floral phenotype in Petunia hybrida.

It is shown that Picotee and Star petunias carry the same short interfering RNA (siRNA)-producing locus, consisting of two intact CHS-A copies, PhCHS- a1 and PhCHs-A2, in a tandem head-to-tail orientation, indicating that the bicolor floral phenotype is caused by the spatially regulated post-transcriptional silencing of both chalcone synthase A genes.

Co-suppression in transgenicPetunia hybrida expressing chalcone synthase A (chsA)

GUS histochemical staining analysis showed that co-Suppression occurred specifically during the development of flowers and co-suppression required the mutual interaction of endogenous genes and transgenes.

Epigenetic inactivation of chalcone synthase-A transgene transcription in petunia leads to a reversion of the post-transcriptional gene silencing phenotype.

Transcription run-on assays confirmed that the production of white flowers is caused by post-transcriptional gene silencing (PTGS), and indicated that transgene transcription is repressed in the revertant plants, providing evidence that induction of PTGS depends on the transcription rate.

Suppression of O-methyltransferase gene by homologous sense transgene in quaking aspen causes red-brown wood phenotypes

The results support the notion that the occurrence of sense cosuppression depends on the degree of sequence homology and endogene expression.

Flower color modification of Petunia hybrida commercial varieties by metabolic engineering

The results clearly indicate the usefulness of metabolic engineering of the flavonoid biosynthetic pathway to modify flower color.

Dominant inheritance of white-flowered and herbicide-resistant traits in transgenic gentian plants

The results clearly showed that these two traits are inherited dominantly as linked traits in the T1 progeny, suggesting that these transgenic plants are useful resources for production of white-flowered gentians.

An anti-sense chalcone synthase gene in transgenic plants inhibits flower pigmentation

It is shown that constitutive expression of an 'anti-sense' chalcone synthase gene in transgenic petunia and tobacco plants results in an altered flower pigmentation due to a reduction in levels of both the messenger RNA for the enzyme and the enzyme itself.

It is hypothesized that the DNA modification results in nonfunctional elements in plants that contain both modified and unmodified elements, suggesting that the modification can occur in a progressive manner.

Reversible methylation and inactivation of marker genes in sequentially transformed tobacco plants

Surprisingly, both the methylation and inactivation of T‐DNA‐I genes occurred only in plants containing both T‐DNAs: when self‐fertilization or backcrossing produced progeny containing only T‐ DNA‐I, expression of the genes on this T-DNA was restored and the corresponding promoters were partially or completely demethylated.

A semi‐dominant allele, niv‐525, acts in trans to inhibit expression of its wild‐type homologue in Antirrhinum majus.

Possible mechanisms for the trans‐acting effect of niv‐525 and its relationship to other examples of allelic interactions, such as transvection in Drosophila melanogaster, are discussed.

A binary plant vector strategy based on separation of vir- and T-region of the Agrobacterium tumefaciens Ti-plasmid

The interaction of two compatible plasmids, one containing the vir-region, the other carrying the T-DNA on a wide host-range replicon are reported, which allows introduction of the manipulated T- DNA into plant cells.

The high efficiency, approximately equal to 10-fold greater than that observed using current methods without enrichment procedures, is obtained by using a DNA template containing several uracil residues in place of thymine, which is applied to mutations introduced via both oligonucleotides and error-prone polymerization.
