6 problemsLichen morphogenesis
A yellow lichen on bark has organized layers built by organisms with separate genomes. What makes its fungus and alga assemble that shared body?
Paulinella protein import
A Paulinella amoeba carries a photosynthetic compartment descended from a bacterium. It makes essential proteins outside that compartment—how do those proteins cross its inner membrane to work inside?
Arbuscule maintenance
Does nutrient delivery by a fungal branch inside a root influence how long the plant maintains it?
Coral bleaching
Heat stress can disrupt the partnership between corals and their photosynthetic symbionts. Which cellular pathways cause symbiont loss in different conditions?
Eukaryogenesis
Complex cells with nuclei descended from simpler ancestors. How did their internal compartments, mitochondria, and distinctive cellular organization come together?
