Global Transcriptional Profiling of the Cyanobacterium Chlorogloeopsis fritschii PCC 9212 in Far-Red Light: Insights Into the Regulation of Chlorophyll d Synthesis
TL;DR: This study shows that Chl d synthesis is regulated by RfpABC; however, most other transcriptional changes leading to the FRL physiological state are notregulated by RFPABC; and it is shown that erythromycin induces Chld d synthesis in vivo.
In situ Dynamics of O2, pH, Light, and Photosynthesis in Ikaite Tufa Columns (Ikka Fjord, Greenland)-A Unique Microbial Habitat.
TL;DR: In situ O2 measurements, as well as underwater variable chlorophyll fluorescence measurements of photosynthetic activity, demonstrated high levels of oxygenic photosynthesis in this extreme gradient environment with strong irradiance-driven O2 dynamics ranging from anoxia to hyperoxic conditions in the ikaite matrix, albeit the local formation of gas bubbles buffered the day-night dynamics of O2 in the tufa columns.

TL;DR: A variety of cyanobacterial species, phylogenically distant from each other, seems to use a Chl f antenna in far-red environments, such as under dense biomats, in colonies, or under far- red LED light.

Excitation energy transfer and electron-vibrational coupling in phycobiliproteins of the cyanobacterium Acaryochloris marina investigated by site-selective spectroscopy.
TL;DR: Excitation energy transfer and electron-vibrational coupling in PBPs have been investigated by selectively excited fluorescence spectra and reveal a rich spectral substructure implying that the respective PCB chromophores are bound to different protein environments.

Spectral signatures of five hydroxymethyl chlorophyll a derivatives chemically derived from chlorophyll b or chlorophyll f
TL;DR: The spectral features and chromatographic properties of these modified Chls are important for identifying potential intermediates in the biosynthesis of Chls such as Chl f and Chl d and for identification of any new Chls in nature.

A PROPOSED STRUCTURE FOR CHLOROPHYLL d

TL;DR: In this paper, a 2-desvinyl-2-formyl-chlorophyll-a was identified and its probable identity with chlorophyll d was discussed in detail.

FURTHER EVIDENCE OF THE RELATION BETWEEN 2-DESVINYL-2-FORMYL-CHLOROPHYLL-a AND CHLOROPHYLL-d
TL;DR: Results provide further evidence that chlorophyll-d is 2-desvinyl-2-formyl-chlorophyll -a, and all thalli of Rhodomela larix yielded chlorophylla but in extremely small amounts.

Chlorophyll d, a green pigment of red algae
TL;DR: Red algae (Rhodophyta) are sharply distinguished from all other plants with respect to anatomy, life history, and the occurrence of certain proteinaceous pigments, and whether or not this distinct,iveness is reflected byThe chlorophylls of several marine species of red algae are investigated.
Four Universal Forms of Chlorophyll a
TL;DR: The red absorption band measured at -196 C in a variety of chloroplast preparations with four major component curves representing forms of chlorophyll a having peaks at 661.
