WebMar 31, 2024 · The promoter sequences of certain CsJAZ genes lacked some types of cis-acting regulatory elements, but the expression patterns revealed that all CsJAZ genes could respond to all five treatments. For example, we could not find high temperature response-related cis -acting regulatory elements in each CsJAZ gene of tea plants. WebCis-acting elements are not part of the coding sequences of the gene they regulate: they may be near the promoter or the 5’ region of the gene, and in some cases they may be many kilobases...
Webcis-and trans- Regulatory ElementsThe lac operon includes DNA sequences that do not encode proteins, but are instead binding sites for proteins that regulate transcription of the operon. In the lac operon, these sequences are called P (promoter), O (operator), and CBS (CAP-binding site). Collectively, sequence elements such as these are called cis … WebMar 18, 2013 · The expression domain of a gene, however, is often the sum of inputs from multiple enhancers (and other cis-regulatory elements), each active in only a subset of contexts (for example, Ref. 47 ...
