Phycobilisomes

Light energy harvesting structures attached to the THYLAKOID MEMBRANES of CYANOBACTERIA and RED ALGAE. These multiprotein complexes contain pigments (PHYCOBILIPROTEINS) that transfer light energy to chlorophyll a.

1.	Starvation 10/31/2008 - "The enormous macromolecular phycobilisome antenna complex (>4 MDa) in cyanobacteria and red algae undergoes controlled degradation during certain forms of nutrient starvation. " 03/01/1994 - "We have developed a visual screen to obtain mutants unable to degrade their phycobilisomes upon nutrient starvation. " 01/01/2007 - "Here we study the effect of inactivation of dspA (an nblS homologue) and an nblR-like gene on phycobilisome degradation in Synechocystis sp. PCC 6803, under nitrogen starvation. " 12/01/2004 - "This corroborates studies on the sequential degradation of phycobilisomes upon nitrogen starvation. " 12/21/2021 - "We developed a genetic modification system for this strain and generated a ΔnblA mutant that exhibited resistance to phycobilisome degradation upon nitrogen starvation. "
2.	Hypochromic Anemia (Chlorosis) 11/21/2008 - "Phycobilisome degradation leads to a color change of the cells from blue-green to yellow-green, referred to as bleaching or chlorosis. " 02/05/2001 - "Phycobilisome degradation is an ordered proteolytic process, visible by a color change of the cyanobacterial cell from blue-green to yellow-green (chlorosis). " 07/01/2012 - "After 12 h, cell growth decreased and chlorosis started with degradation of the nitrogen-rich phycobilisomes. " 02/24/2006 - "Cyanobacterial light-harvesting complexes, the phycobilisomes, are proteolytically degraded when the organisms are starved for combined nitrogen, a process referred to as chlorosis or bleaching. " 09/01/2002 - "The nblA family of genes encodes for small proteins necessary for the ordered degradation of phycobilisomes under certain stress conditions, a process known as chlorosis. "
3.	Rupture 01/01/2017 - "Transmission electron microscopy (TEM) micrographs of trichomes evidenced the gas vesicles rupture but also revealed a rearrangement of thylakoids and more visible phycobilisomes were observed. " 01/01/1981 - "Rhodoplast envelope rupture appeared to be accompanied by phycobilisome loss from the thylakoids."
4.	Ganglion Cysts (Ganglion) 01/01/1998 - "Immunogold localization showed that there was a statistically significant occurrence of the red algal phycobilisome pigment r-phycoerythrin within these rhodoplast digestive vacuoles, but not in other compartments of this cell type (endoplasmic reticulum, mitochondria, nucleus) or in other tissues (abdominal ganglion).
