Cardiolipin increases in chromatophores isolated from Rhodobacter sphaeroides after osmotic stress: structural and functional roles

open access: yesJournal of Lipid Research, 2009
Chromatophores isolated from cells of Rhodobacter sphaeroides exposed to hypertonic solutions were enriched in cardiolipin (CL). Because CL levels are raised by increasing the incubation time of R.

Basonuclin-2 requirements for zebrafish adult pigment pattern development and female fertility.

open access: yesPLoS Genetics, 2009
Relatively little is known about the generation of adult form. One complex adult trait that is particularly amenable to genetic and experimental analysis is the zebrafish pigment pattern, which undergoes extensive remodeling during post-embryonic ...

Incidence of the thermal transition in the range of 45-5°C in chromatophores present in the wings of Schistocerca americana [version 1; peer review: 1 approved, 2 approved with reservations]

open access: yesF1000Research, 2019
The variation of the color intensity of the chromatophores present in the wings of Schistocerca americana was analyzed by exposing 31 specimens to thermal transitions within the range of 45 - 5 °C.

Protein translocons in photosynthetic organelles of Paulinella chromatophora

open access: yesActa Societatis Botanicorum Poloniae, 2014
The rhizarian amoeba Paulinella chromatophora harbors two photosynthetic cyanobacterial endosymbionts (chromatophores), acquired independently of primary plastids of glaucophytes, red algae and green plants.

Energy conversion in Purple Bacteria Photosynthesis [PDF]

open access: yes, 2011
The study of how photosynthetic organisms convert light offers insight not only into nature's evolutionary process, but may also give clues as to how best to design and manipulate artificial photosynthetic systems -- and also how far we can drive natural
