New Phytol 186:239-50. 2010

- The effect of stress on genome regulation and structure
Andreas Madlung
University of Puget Sound, Department of Biology, Tacoma, WA 98416, USA
Ann Bot (Lond) 94:481-95. 2004
..CONCLUSIONS: A common response to stresses may be the relaxation of epigenetic regulation, leading to activation of suppressed sequences and secondary effects as regulatory systems attempt to re-establish genomic order...

Philos Trans R Soc Lond B Biol Sci 358:1149-55. 2003
..We hypothesize that loss of epigenetic suppression of these sequences, here defined as the heterome, results in genomic instability including silencing of single-copy genes...

Am J Bot 96:1656-64. 2009
..Our results suggest that somatic aneuploidy can be tolerated in Arabidopsis polyploids, but there is no evidence that this type of aneuploidy leads to stable novel cytotypes...
