478 genes regulated similarly by four ALS-inhibiting herbicides were tested for over-representation against Arabidopsis thaliana ATH1 (23,334 genes) background population by using BioMaps tool at VirtualPlant (http://virtualplant.bio.nyu.edu/cgi-bin/vpweb2/). Categories enriched at P < 0.01 are listed here. The method used to calculate P value of over-representation was hypergeometric distribution
* One gene was not assigned and hence total number of observed genes was reduced to 477
