This is THE bioinfo tool we were looking for, but had to develop ourselves - amazing work, Dolly (@dollymehta.bsky.social‬)!!
A GOLD MINE if you work with post-transcriptional regulation in #chloroplast!!

My lab's very first manuscripts are out!!!!

- We identified nearly 60 conserved RNA structures in plastids #chloroplast #RNA
- We found that transcriptional response to warm temperatures in whole seedling is confounded by response at organ level #thermomorphogenesis
