Turnover-synthesis of chloroplast DNA in developing chloroplasts [PDF]

Journal of Bacteriology, 1978
The mechanism for the turnover-synthesis of chloroplast DNA in the absence of net synthesis during the chloroplast maturation in Euglena gracilis was determined. DNA synthesis was measured by incorporation of32Pi into chloroplast DNA. The density label, 15N, was incorporated to examine the mechanism of turnover-synthesis. The newly synthesized segments

A Plastid RNA Polymerase-Associated Protein Is Involved in Early Chloroplast Development in Rice

Agronomy, 2023
Plastid-encoded RNA polymerase (PEP) regulates the expression of chloroplast genes involved in photosynthesis and chloroplast development in rice. The PEP-associated protein (PAP) PAP7/pTAC14 is essential for the formation of the PEP complex.

PPR647 Protein Is Required for Chloroplast RNA Editing, Splicing and Chloroplast Development in Maize. [PDF]

Int J Mol Sci, 2021
Chloroplasts play an essential role in plant growth and development. Any factors affecting chloroplast development will lead to abnormal plant growth. Here, we characterized a new maize mutant, albino seedling mutant 81647 (as-81647), which exhibits an ...

Proteomic Responses of Dark-Adapted Euglena gracilis and Bleached Mutant Against Light Stimuli

Frontiers in Bioengineering and Biotechnology, 2022
Euglena gracilis (E. gracilis) has secondary endosymbiotic chloroplasts derived from ancient green algae. Its chloroplasts are easily lost under numerous conditions to become permanently bleached mutants.

Chloroplast dismantling in leaf senescence [PDF]

, 2021
In photosynthetic plant cells, chloroplasts act as factories of metabolic intermediates that support plant growth. Chloroplast performance is highly influenced by environmental cues.

Disruption of a Rice Chloroplast-Targeted Gene OsHMBPP Causes a Seedling-Lethal Albino Phenotype

Rice, 2020
Background Chloroplast development is coordinately regulated by plastid- and nuclear-encoding genes. Although many regulators have been reported to be involved in chloroplast development, new factors remain to be identified, given the complexity of this ...

PIF3 is a repressor of chloroplast development [PDF]

Proceedings of the National Academy of Sciences, 2009
The phytochrome-interacting factor PIF3 has been proposed to act as a positive regulator of chloroplast development. Here, we show that the pif3 mutant has a phenotype that is similar to the pif1 mutant, lacking the repressor of chloroplast development PIF1, and that a pif1pif3

Image_3_Stromal Protein Chloroplast Development and Biogenesis1 Is Essential for Chloroplast Development and Biogenesis in Arabidopsis thaliana.TIF [PDF]

, 2022
Although numerous studies have been carried out on chloroplast development and biogenesis, the underlying regulatory mechanisms are still largely elusive. Here, we characterized a chloroplast stromal protein Chloroplast Development and Biogenesis1 (CDB1).

A shared mucosal gut microbiota signature in primary sclerosing cholangitis before and after liver transplantation

Hepatology, EarlyView., 2022
In this study of the gut mucosal microbiota in primary sclerosing cholangitis (PSC), we found consistent microbiota features associated with PSC and recurrent PSC, PSC with inflammatory bowel disease and a persistent gut dysbiosis after liver transplantation Abstract Background and Aims Several characteristic features of the fecal microbiota have been ...
