Figure 4From: Identification of functional cis-regulatory elements by sequential enrichment from a randomized synthetic DNA libraryIdentified SynCREs can mediate pathogen-responsive expression in mature Arabidopsis plants. Five week-old Arabidopsis transgenic plants carrying the indicated SynE expression constructs were challenged with the oomycete Hyaloperonospora arabidopsidis isolate Emwa (A and B) and expression of the LUC reporter gene was monitored and compared to unchallenged control plants (C and D). Images were taken 6Â hours upon application of H. arabidopsidis spores. The temporal dynamics of LUC activity under H. arabidopsidis challenge can be viewed in Additional files 9 and 10.Back to article page
