Abstract excerpt
The Antirrhinum majus transposon Tam3 undergoes low temperature-dependent transposition (LTDT). Growth at 15 degrees C permits transposition, whereas growth at 25 degrees C strongly suppresses it. The degree of Tam3 DNA methylation is altered somatically and positively correlated with growth temperature, an exceptional epigenetic system in plants. Using a Tam3-inactive line, we show that methylation change...
