Natural epigenetic variation in Arabidopsis

Magnus Nordborg
Gregor Mendel Institute, Vienne, Autriche

Advances in sequencing technology are finally making it possibly to investigate genetic and epigenetic variation in populations. We have characterized the genomes, DNA methylomes, and transcriptomes of over 1000 natural inbred lines of Arabidopsis. The data elude the history of the species, and provide a first glimpse into how DNA methylation varies globally, and how it may evolve. Our results suggest that much of the observed epigenetic variation has a strong genetic basis, in particular in the form of transposon variation. More surprisingly, several major trans-acting loci are identified, and there is evidence for geographic variation suggestive of selection
