Low temperature-inducible wheat WCS120 gene promoter

摘要

The Wcs120 gene encodes a highly abundant protein which appears to play an important role during cold acclimation of wheat. To understand the regulatory mechanism controlling its expression at low temperature (LT-responsiveness), the promoter region has been characterized. The data indicate the involvement of putative enhancer elements, negative and positive regulatory regions in the transcriptional regulation of this gene. Further, the promoter was found to be cold-inducible in different freezing tolerant and sensitive monocot and dicot species, suggesting that universal transcription factors responsive to LT may be present in all plants. Therefore this promoter could be used to drive the genes needed for LT tolerance in sensitive species.
