OsCPK12-OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice. [PDF]
Adv Sci (Weinh)OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.

SYNTHESIS OF CHLOROPLAST DNA IN ISOLATED CHLOROPLASTS [PDF]
The Journal of Cell Biology, 1968 Chloroplasts isolated from Euglena gracilis incorporated both tritiated thymidine 5'-triphosphate and tritiated deoxyadenosine 5'-triphosphate into an acid-stable fraction. The incorporation was dependent on the presence of all four deoxynucleoside triphosphates and was sensitive to treatment with deoxyribonuclease and actinomycin D.

A ‘foldosome’ in the chloroplast? [PDF]
Plant Signaling & Behavior, 2009 The proper functioning of many cytosolic proteins involved in signal transduction depends on protein folding steps carried out cooperatively by a multichaperone complex containing the Hsp90 and Hsp70 machineries. We have recently found that also in the chloroplast the Hsp90 and Hsp70 machineries form a multichaperone complex, although chloroplast Hsp90

Traffic, 2007 Chloroplasts are descendants of cyanobacteria and divide by binary fission. Several components of the division apparatus have been identified in the past several years and we are beginning to appreciate the plastid division process at a mechanistic level.

Reactive Oxygen Species Signaling Pathways: Arbiters of Evolutionary Conflict?
Oxygen, 2022 In the history of life, cooperation between biological units has led to increased complexity, e.g., eukaryotic cells and multicellular organisms. Cooperation requires limiting the gains of “defectors” in favor of the cooperative higher-level unit.

The formation of homogentisate in the biosynthesis of tocopherol and plastoquinone in spinach chloroplasts [PDF]
, 1982 Homogentisate is the precursor in the biosynthesis of -tocopherol and plastoquinone-9 in chloroplasts. It is formed of 4-hydroxyphenylpyruvate of the shikimate pathway by the 4-hydroxyphenylpyruvate dioxygenase.

The journey of preproteins across the chloroplast membrane systems
Frontiers in Physiology, 2023 The photosynthetic capacity of chloroplasts is vital for autotrophic growth in algae and plants. The origin of the chloroplast has been explained by the endosymbiotic theory that proposes the engulfment of a cyanobacterium by an ancestral eukaryotic cell

Journal of Lipid Research, 1967 The formation of chloroplasts in dark-grown cells of Euglena gracilis was induced by exposing the cells to constant illumination. Following a lag, the cells accumulated chlorophyll and galactosyl diglycerides simultaneously at almost linear rates.The ...

Blue Light Receptor PHR2-Mediated Spectrum Antiviral Immunity. [PDF]
Adv Sci (Weinh)Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.
