Scientists have sought to restore the ecology and utility of this tree species by adding resistance through genetic engineering. For the backstory listen to <a href="https://www.talkingbiotechpodcast.com/009-saving-the-american-chestnut-lettuce-history-and-modern-improvement/">Episode 9 (2015) of this podcast series</a>. This week’s interview is with graduate student Erik Carlson. Erik <a href="https://bsppjournals.onlinelibrary.wiley.com/doi/full/10.1111/mpp.13165">recently published a paper i</a>n Molecular Plant Pathology that describes a new regulatory control of the gene that confers resistance to Chestnut Blight. We discuss the background of the project, where the project stands, and the regulatory environment of repatriating a forest with engineered trees.<br>
