Transient expression of the GmROOT promoter family, in Lima Bean cotyledons, reported as a percent of intensity obtained with the CaMV35S promoter. Below graph, images of peak expression with links to 100 h time-lapse animations of GFP expression. Expression of Root-specific promoters or any tissue-specific promoters in this target tissue (lima bean cotyledons) is normal as large amounts of DNA are introduced and expressed prior to integration.
