Photosystem I Protein Complex (Photosystem I)

A large multisubunit protein complex that is found in the THYLAKOID MEMBRANE. It uses light energy derived from LIGHT-HARVESTING PROTEIN COMPLEXES to drive electron transfer reactions that result in either the reduction of NADP to NADPH or the transport of PROTONS across the membrane.

" 01/01/2016 - "A coordinate response to iron deficiency, which leads to dismantling of the photosynthetic electron transfer chain and in particular of photosystem I, also causes a decrease of Mac1. " 11/01/2013 - "The changes observed photosystem I activity of lettuce plants exposed to iron deficiency were investigated.

2.	Infections 01/25/2016 - "The objective of this study was to clarify the responses of photosystem I (PSI) and photosystem II (PSII) to Pst infection in tobacco leaves. " 10/15/2023 - "We found that the photosystem I (PSI) subunit (PSaC) and ATP synthase subunit α (ATPsyn-α) genes were up-regulated in the resistant cultivar following SMV-G7H and SMV-G5H infections compared to the susceptible cultivar. " 01/01/2016 - "Although the maximal quantum yield of photosystem II (PSII) and the activity of the photosystem I (PSI) complex decreased as Pst infection progressed, damage to PSI and PSII after infection was reduced under light conditions compared to dark conditions. " 09/17/1990 - "In Synechococcus sp. cells AS-1 cyanophage infection gradually inhibits the photosystem II mediated photosynthetic electron flow whereas the activity of photosystem I is apparently unaffected by the cyanophage infection. " 01/24/2022 - "Among these DEPs, key proteins involved in YongM-host interaction may be photosystem I P700 chlorophyll-a apolipoprotein, carbon dioxide concentration mechanism protein, cytochrome B, and some YongM infection lysis-related enzymes.

Tetraploidy 01/28/2015 - "nankingense, while PSAA (photosynthesis-related plastid gene representing photosystem I) and EF-1α (elongation factor-1α) were the most stable in tetraploid and hexaploid C. " 01/01/2015 - "This study was to explore leaf photosynthetic characterization with emphasis on the coordination between photosystem II (PSII) and photosystem I (PSI) in tetraploid and its autodiploid honeysuckle (TH and DH) upon salt stress (300 mM NaCl).

"
5.	Starvation 07/06/2023 - "This Pi-starvation-induced mechanism dampens both electron transport rates through photosystem I and II (ETRI and ETRII) and thus mitigates the electron-excessive stress in mesophyll cells. " 11/17/2011 - "The PSI-CP43' supercomplex of the cyanobacterium Synechocystis PCC 6803, grown under iron-starvation conditions, consists of a trimeric core Photosystem I (PSI) complex and an outer ring of 18 CP43' light-harvesting complexes. " 02/01/2007 - "IsiA, however, does seem to protect the cells from the stress generated by iron starvation, initially by increasing the size of the photosystem I antenna. " 06/07/2004 - "The cyanobacterium Synechococcus PCC 7942 grown under iron starvation assembles a supercomplex consisting of a trimeric Photosystem I (PSI) complex encircled by a ring of 18 CP43' or IsiA complexes.
