ProteomicsThe Paulinella chromatophore N-terminome
The cercozoan amoeba Paulinella chromatophora contains photosynthetic organelles - termed chromatophores - that evolved from a cyanobacterium ~100 million years ago, independently from plastids in plants and algae. Despite its more recent origin, at least one third of the chromatophore proteome cons...

ProteomicsCephalopod Chromatophore Proteomics
using the first annotated squid chromatophore proteome together with microscopy, we identified likely biochemical components of this reflective coloration as structural reflectin proteins distributed in cells that completely envelop each chromatocyte. Within the chromatocytes, where the pigment mole...

ProteomicsMetabolic and genetic integration of the chromatophore
The cercozoan amoeba Paulinella chromatophora contains photosynthetic organelles - termed chromatophores - that evolved from a cyanobacterium independently from plastids in plants and algae. Despite the more recent origin of the chromatophore, it shows tight integration into the host cell. It import...

TranscriptomicsConserved and lineage-specific mechanisms drive chromatophore differentiation in reptiles
We employed single-cell RNA sequencing using the 10X Genomics platform to study chromatophore development in reptilian embryonic skin. Pigment cells have been well characterized in fish, but little is known about their development in reptiles. We analyzed dorsal skin from corn snakes and bearded dra...

MetabolomicsGenetic mapping and molecular mechanism behind color variation in the Asian vine snake

BACKGROUND: Reptiles exhibit a wide variety of skin colors, which serve essential roles in survival and reproduction. However, the molecular basis of these conspicuous colors remains unresolved.

RESULTS: We investigate color morph-enriched Asian vine snakes...

ProteomicsProteome of an early evolutionary stage photosynthetic organelle in the amoeba Paulinella chromatophora
The endosymbiotic acquisition of mitochondria and plastids >1 Ga ago profoundly impacted eukaryote evolution. Early stages of organelle integration however remain poorly understood. The amoeba Paulinella chromatophora contains more recently established cyanobacterium-derived photosynthetic organelle...
