TILLING is an effective reverse genetics technique for Caenorhabditis elegans

Background TILLING (T argeting I nduced L ocal L esions i n G enomes) is a reverse genetic technique based on the use of a mismatch-specific enzyme that identifies mutations in a target gene through heteroduplex analysis. We tested this technique in Caenorhabditis elegans, a model organism in which genomics tools have been well developed, but limitations in reverse genetics have restricted the number of heritable mutations that have been identified.
