Summary for non-specialists: Science paper on epigenetics

Published on: June 21, 2012

One of the things I wanted to do on this blog was to highlight recent plant science journal articles, and when I found back-to-back papers on Arabidopsis research in Science I thought they would be a good place to start.

But when I started to read, I realised the obvious – my cell wall biochemistry background will be no help at all when trying to understand other areas of plant science research. But I still want to highlight high-impact articles like this on the blog, so I decided to have a Summary for non-specialists series. Please feel free to comment if I’ve got something horribly wrong, and of course if anyone would like to provide a Summary by a Specialist that would be great!

Highlighted article

Qian et al., June 2012. A Histone Acetyltransferase Regulates Active DNA Demethylation in Arabidopsis. Science 336: 1445-1447

Prior to this research, little was known about the regulation of DNA methylation, or how DNA and histone modifications were related. Here, Qian et al. define a process in which histone modification is an essential part of DNA methylation. This research opens the door to deeper understanding of the regulation and mechanism of DNA modification, and possible manipulation of epigenetic mechanisms.
