  • Porphyrogenes peterwegii

     Pupa of the butterfly Porphyrogenes peterwegii "peering" out of its leafy nest with false eyes, which in turn mimic the eyes of a snake, thereby protecting the pupa from small feather-brained  birds.

  • Consequences of HD-ZIPIII dysregulation

    How do organisms create such complex and beautiful shapes? And how do they do it so reproducibly? Plants are an excellent system to study these questions. For instance, the HD-ZIPIII family of transcription factors are >700 million years old and regulate nearly all aspects of plant development. Consequences of HD-ZIPIII dysregulation on plant morphology are severe (pictured here). Understanding how HD-ZIPIII proteins work is a central theme of the lab.

  • Bacterial Respiratory Complex

    Structural model of a bacterial respiratory complex III: remember that when you respire, your complex III perspires to produce your body's energy.

  • Archaea

    Haloferax volcanii motility mutants stab-inoculated on a 0.3% agar motility plate. The “halos” and “rings” likely reflect the motility of this archaeon following gradients of attractant or repellent chemicals. 

  • ERK1/2 signaling pathway

     ERK1/2 signaling pathway regulates exocytosis and tumor invasion through phosphorylation of the exocyst complex. 

Biology is fundamental to our changing world. The 21st century challenge for our students, our scholars, and the greater society is to understand our place in this changing world and to create fundamental knowledge for informed policies, economies, and social structure.

Nuclear compensatory evolution driven by mito-nuclear incompatibilities

Dr. Débora Princepe
- | DRL 4C2 and via Zoom

Abstract: The mitochondrial DNA (mtDNA) plays a fundamental role in cell respiration and the maintenance of eukaryotic life. However, respiration also requires proteins encoded in the nuclear…
