Activity of elements from the tobacco cryptic promoter, tCUP, in conifer tissues

From: In Vitro Cellular & Developmental Biology | Date: March 1, 2003| Author: | Copyright information

SUMMARY

Cryptic gene regulatory elements are inactive at their native locations in the genome but are fully functional when positioned adjacent to genes in transgenic plants. Although they are widespread among diverse organisms, they have not yet been described in gymnosperms. tCUP is a strong constitutive cryptic promoter from tobacco that harbors transcriptional enhancers, a TATA-less core promoter, and a translational enhancer. tCUP is active in all conifer species tested including white spruce, white pine, Loblolly pine, larch, and Douglas fir. The tCUP enhancers are fully active in white ...
