Turned on by stress. Plant retrotransposons.
All known active plant retrotransposons are largely quiescent during development but activated by stresses, including wounding, pathogen attack and cell culture. This may reflect a survival strategy based on plant biology, or retrotransposons could be the stress-induced generators of genomic diversity proposed by McClintock.
