Evolutionary dynamics of an epigenetic switch in a fluctuating environment
Adaptation and survival in fluctuating environments is an evolutionary challenge faced by organisms. Epigenetic switches (bistable, molecular systems built from self-reinforcing feedback loops) have been suggested as a mechanism of bet-hedging and adaptation to fluctuating environments. These epigenetic systems are capable of spontaneously switching between phenotypes in the absence of DNA muta...
متن کاملHistory of plant tissue culture.
Plant tissue culture, or the aseptic culture of cells, tissues, organs, and their components under defined physical and chemical conditions in vitro, is an important tool in both basic and applied studies as well as in commercial application. It owes its origin to the ideas of the German scientist, Haberlandt, at the beginning of the twentieth century. The early studies led to root cultures, em...

متن کاملThe alc-GR system: a modified alc gene switch designed for use in plant tissue culture.
The ALCR/alcA (alc) two-component, ethanol-inducible gene expression system provides stringent control of transgene expression in genetically modified plants. ALCR is an ethanol-activated transcription factor that can drive expression from the ALCR-responsive promoter (alcA). However, the alc system has been shown to have constitutive expression when used in plant callus or cell suspension cult...
