Global expression profiling to study the effect of imidazolinone herbicide treatment on Arabidopsis thaliana

Using whole genome microarray (Affymetrix ATH1) we studied the transcriptional response of Arabidopsis thaliana to imidazolinone (Arsenal) herbicde that inhibits acetolactate synthase (ALS) enzyme and thus disrupts branched chain amino acid biosynthesis. A number of genes related to amino acid, protein metabolism, growth, regulatory networks, respiratory pathways, stress, defense and secondary metabolism were altered.
