Functional analysis of 150 deletion mutants in Saccharomyces cerevisiae by a systematic approach

In a systematic approach to the study of Saccharomyces cerevisiae genes of unknown function, 150 deletion mutants were constructed (1 double, 149 single mutants) and phenotypically analysed. Twenty percent of al...

Analysis of in vivo correction of defined mismatches in the DNA mismatch repair mutants msh2, msh3 and msh6 of Saccharomyces cerevisiae

We have analysed the correction of defined mismatches in wild-type and msh2, msh3, msh6 and msh3 msh6 mutants of Saccharomyces cerevisiae in two different yeast strain backgrounds by transformation with plasmid ...

Condensation of chromatin in transcriptional regions of an inactivated plant transgene: evidence for an active role of transcription in gene silencing

The chromatin structures of two epigenetic alleles of a transgene were investigated by measuring the local accessibility of transgene chromatin to endonucleases. The two epialleles represented the active, hyp...

Inactivation of gene expression in transgenic plants

In recent years more and more reports have appeared in the literature describing instabilities of gene expression in transgenic plants. Many of these instabilities, which can be classified as transcriptional o...

The transformation booster sequence from Petunia hybrida is a retrotransposon derivative that binds to the nuclear scaffold

The transformation booster sequence (TBS) from Petunia hybrida enhances transformation frequencies in P. hybrida, Nicotiana tabacum and Zea mays. TBS also stimulates homologous inter- and intramolecular recombina...

Epigenetic variants of a transgenic petunia line show hypermethylation in transgene DNA: an indication for specific recognition of foreign DNA in transgenic plants

We analysed de novo DNA methylation occurring in plants obtained from the transgenic petunia line R101-17. This line contains one copy of the maize A1 gene that leads to the production of brick-red pelargonidin p...

Epigenetic changes in the expression of the maize A1 gene inPetunia hybrida: Role of numbers of integrated gene copies and state of methylation

ThePetunia hybrida mutant RL01 is white flowering due to a genetic block in the anthocyanin pathway. The introduction of the maize Al cDNA under the control of the CaMV 35S RNA promoter leads to the production of...

Defective phosphoinositide metabolism in primary hypertension

An increase in free cytosolic calcium content has been reported in essential hypertension. Since within the membrane, the phosphoinositides participate in the control of cell calcium homeostasis, we investigat...

Synchronized tobacco protoplasts are efficiently transformed by DNA

A system for the synchronization of tobacco protoplasts was developed using aphidicolin, a mycotoxin which inhibits alpha-like DNA polymerase. Synchronized SR1 tobacco protoplasts were transformed with plasmid...
