What are HOX genes doing in planaria?

Our most recent preprint aims to shed some light on this puzzle

Before diving in, a brief history of past efforts to understand HOX genes in planaria is warranted

biorxiv.org/content/10.110…

@ScienceStowers @HHMINEWS @biorxivpreprint The ancestral role of HOX genes has puzzled biologists for decades, a problem that ultimately intersected with the centuries-old debate of how the segmented body plan emerged in animals

Our @ScienceStowers lab's most recent effort to understand regeneration has just been published @ScienceMagazine.

science.sciencemag.org/content/369/65…

The story began sometime in 2008 with an idea after hearing Anne Brunet @BrunetLab give a talk at my old institution @UUtah I wondered whether we could exploit the remarkable qualities of killifish, such as genetics, diapause, and rapid maturation, to study vertebrate adult regeneration?

I am on my way to @SastraUniv to receive the 2019 Obaid Siddiqi Award.

I want to pause and reflect on the fundamental contributions made by this extraordinary Indian mind and global scientist to human knowledge.

@ScienceStowers @royalsociety @theNASciences I never met Obaid, but I first learned of Dr. Siddiqi when I was learning about fine cistron (gene) mapping in college @VanderbiltU in the early 1980s from Dr. Gisela Mosig
