Gene switches have potential applications for the regulation of transgene expression in plants and animals. Recently, we have developed a two-hybrid ecdysone receptor (EcR) gene switch using chimera 9 [CH9, a chimera between helices 1-8 of Homo sapiens retinoid X receptor (HsRXR) and helices 9-12 of
The ability to regulate spatial and temporal expression of genes is a useful tool in biotechnology as well as studies of functional genomics. Such regulation can provide information concerning the function of a gene in a developmental context while avoiding potential harmful effects due to
Full understanding of mechanisms that control seed dormancy and germination remains elusive. Whereas it has been proposed that translational control plays a predominant role in germination, other studies suggest the importance of specific gene expression patterns in imbibed seeds. Transgenic plants
