T-DNA tagging of a pathogen inducible promoter in Arabidopsis thaliana.

Summary Many events associated with the plant defence responses are regulated on the transcriptional level. Here we report the results of a promoter tagging approach to identify promoters that are induced upon pathogen attack in Arabidopsis thaliana. A line was identified in a T-DNA UidA tagged Arabidopsis library with induced GUS expression after Botrytis cinerea infection around the site of fungal infection.
