Towards a critical understanding of the photosystem II repair mechanism and its regulation during stress conditions
Photosystem II (PSII) is vulnerable to high light (HL) illumination resulting in photoinhibition. In addition to photoprotection mechanisms, plants have developed an efficient PSII repair mechanismExpand

ZEBRA-NECROSIS, a thylakoid-bound protein, is critical for the photoprotection of developing chloroplasts during early leaf development.
The zebra-necrosis (zn) mutant of rice (Oryza sativa) produces transversely green/yellow-striped leaves. The mutant phenotype is formed by unequal impairment of chloroplast biogenesis beforeExpand

Loss-of-function of OsSTN8 suppresses the photosystem II core protein phosphorylation and interferes with the photosystem II repair mechanism in rice (Oryza sativa).
STN8 kinase is involved in photosystem II (PSII) core protein phosphorylation (PCPP). To examine the role of PCPP in PSII repair during high light (HL) illumination, we characterized a T-DNAExpand

Age-dependent changes in the functions and compositions of photosynthetic complexes in the thylakoid membranes of Arabidopsis thaliana
Photosynthetic complexes in the thylakoid membrane of plant leaves primarily function as energy-harvesting machinery during the growth period. However, leaves undergo developmental and functionalExpand

Dependence of reaction center-type energy-dependent quenching on photosystem II antenna size.
The effects of photosystem II antenna size on reaction center-type energy-dependent quenching (qE) were examined in rice plants grown under two different light intensities using both wild type andExpand

A Nitrogen-Fixing Subunit Essential for Accumulating 4Fe-4S-Containing Photosystem I Core Proteins1[OPEN]
Loss-of-function mutants of a chloroplastic nitrogen-fixation-subunit-U-type protein showed decreased accumulation of 4Fe-4S-containing photosystem I core proteins. Nitrogen-fixation-subunit-UExpand

Developmental stage-dependent differential gene expression of superoxide dismutase isoenzymes and their localization and physical interaction network in rice (Oryza sativa L.)
Superoxide dismutase (SOD) isoenzymes are essential for scavenging excess reactive oxygen species in living organisms. So far, expression pattern of SOD isoenzymes genes along leaf development plusExpand

Chloroplastic iron-sulfur scaffold protein NFU3 is essential to overall plant fitness
ABSTRACT A previous study showed that Nitrogen-Fixing-subunit-U-type protein NFU3 may act an iron-sulfur scaffold protein in the assembly and transfer of 4Fe-4S and 3Fe-4S clusters in theExpand

A Paradigm of Reactive Oxygen Species and Programed Cell Death in Plants
Plants are continuously exposed to a large variety of biotic and abiotic stresses during their successive stages of development [1-4]. Living organisms have different endogenous strategies toExpand

Production of superoxide from Photosystem II in a rice (Oryza sativa L.) mutant lacking PsbS
BackgroundPsbS is a 22-kDa Photosystem (PS) II protein involved in non-photochemical quenching (NPQ) of chlorophyll fluorescence. Rice (Oryza sativa L.) has two PsbS genes, PsbS1 and PsbS2. However,Expand
