Analysis of flower pigmentation mutants generated by random transposon mutagenesis inPetunia hybrida

The Plant Journal. 13:39-50
Fifty new flower pigmentation mutants in Petunia hybrida using endogenous transposable elements (TEs) as a mutagen were generated. Forty-six mutants displayed somatic and sporogenic instability indicating that they were caused by a TE. Phenotypic ana

Fruit ripening is characterized by dramatic changes in gene expression, enzymatic activities and metabolism. Although the process of ripening has been studied extensively, we still lack valuable information on how the numerous metabolic pathways are

Transgenes and endogenous genes are sensitive to silencing, in particular when the genes are tandemly repeated. Their expression can be transcriptionally or post-transcriptionally repressed, or both. It is remarkable that very often, two or more gene

The substitution pattern of anthocyanin pigments is a main determinant of flower color. Flavonoid 3′,5′-hydroxylase (F3′5′H) is a cytochrome P450 enzyme (Cyt P450) that catalyzes the 3′,5′-hydroxylation of dihydroflavonols, the precursors

The shape and color of flowers are important for plant reproduction because they attract pollinators such as insects and birds. Therefore, it is thought that alterations in these traits may result in the attraction of different pollinators, genetic i

Mutant analyses have given insight into the various parameters that contribute to flower colour and pattern, which is so important for pollination. One important factor is the accumulation of orange, red and purple anthocyanin pigments in the cell va

The regulatory anthocyanin loci, an1, an2, an4 and an11 of Petunia hybrida, and r and c1 from Zea mays, control transcription of different sets of target genes. Both an2 and c1 encode a MYB-type protein. This study reports the isolation of a P. hybri

Posttranscriptional silencing of chalcone synthase (Chs) genes in petunia transformants occurs by introducing T-DNAs that contain a promoter-driven or promoterless Chs transgene. With the constructs we used, silencing occurs only by T-DNA loci which

Summary To induce post-transcriptional silencing of flower pigmentation genes by homologous sense transgenes in transgenic petunias, it is not necessary for the transgenes to be highly transcribed. Even promoterless transgenes can induce silencing. H

In genetically modified plants, the introduced transgenes are sometimes not expressed. They can be silenced. Transgenes can also cause the silencing of endogenous plant genes if they are sufficiently homologous, a phenomenon known as co-suppression.
