But because it's a model plant, we were able to do all sorts of fun and insightful follow-up experiments!
- Varying the lifespan with growth conditions
- Profiling young organs that initiated in older plants
- Genetic dissection of mechanisms, including an epigenetic age-less mutant!

In this study, we found that despite its short life-span, the model plant Arabidopsis shows some pretty remarkable dynamic changes to the epigenetic landscape during organ aging. These changes are not unlike the changes that happen to methylation in some parts of the human genome over decades

Aging drives a program of DNA methylation decay in plant organs Plants display a wide range of life spans and aging rates. Although dynamic changes to DNA methylation are a hallmark of aging in mammals, it is unclear whether similar molecular signatures reflect ra...

Absolutely delighted that our paper on epigenetic dynamics during plant aging is out today in Science!

Chromatin state

This website is extensive, and you can download the original tracks pretty easily: systemsbiology.cau.edu.cn/chromstates/

For ATAC-seq Jacobsen lab has a nice paper with all the methyltransferase mutants as well

This is a closeup image of wheat plants in a disease trail nursery. There are yellow streaks on the otherwise healthy and green leaves caused by bacterial leaf streak

Tough day for small grains research in the Twin Cities. Myself and four scientist colleagues have all been let go from the USDA because we haven't completed our 3 year probationary period - effectively gutting the Cereal Disease Lab.
Taking a few days to be sad before I think about what comes next.

Update: This ***NSF-funded*** study is now published in MBE. Today more than ever, I'm appreciative of what all the people at NSF do to support our science. Let's fight to support them.
