High level transgenic expression of soybean (Glycine max) GmERF and Gmubi gene promoters isolated by a novel promoter analysis pipeline

摘要

BackgroundAlthough numerous factors can influence gene expression, promoters are perhaps the most important component of the regulatory control process. Promoter regions are often defined as a region upstream of the transcriptional start. They contain regulatory elements that interact with regulatory proteins to modulate gene expression. Most genes possess their own unique promoter and large numbers of promoters are therefore available for study. Unfortunately, relatively few promoters have been isolated and characterized; particularly from soybean (Glycine max).
