Breakthrough Technologies Characterization of a Tobacco Bright Yellow 2 Cell Line Expressing the Tetracycline Repressor at a High Level for Strict Regulation of Transgene Expression
Manipulating the expression of a transgene in transient and stable transformed cells is a requirement for many functional analyses. We have investigated the use of the tetracycline-dependent gene expression system developed by Gatz et al. (1992) in tobacco (Nicotiana tabacum L. cv Bright Yellow 2 [BY2]) cells, the most widely used plant cell culture. We have selected a BY2 cell line, named BY2-...

متن کاملCell cycle regulation of the tobacco ribonucleotide reductase small subunit gene is mediated by E2F-like elements.
Ribonucleotide reductase (RNR) is a key enzyme involved in the DNA synthesis pathway. The RNR-encoded genes are cell cycle regulated and specifically expressed in S phase. The promoter of the RNR2 gene encoding for the small subunit was isolated from tobacco. Both in vivo and in vitro studies of the DNA-protein interactions in synchronized BY2 tobacco cells showed that two E2F-like motifs were ...
متن کاملGenetic engineering of yellow betalain pigments beyond the species barrier
Betalains are one of the major plant pigment groups found in some higher plants and higher fungi. They are not produced naturally in any plant species outside of the order Caryophyllales, nor are they produced by anthocyanin-accumulating Caryophyllales. Here, we attempted to reconstruct the betalain biosynthetic pathway as a self-contained system in an anthocyanin-producing plant species. The c...
متن کاملA New Reporter Gene Technology: Opportunities and Perspectives
The paper summarizes the current status of the reporter gene technology and their basics. Reporter gene technology is widely used to monitor cellular events associated with gene expression and signal transduction. Based upon the splicing of transcriptional control elements to a variety of reporter genes, it “reports” the effects of a cascade of signaling events on gene expression inside cells. ...
