A model of chloroplast growth regulation in mesophyll cells [PDF]

open access: yesarXiv, 2015
Chloroplasts regulate their growth to optimize photosynthesis. Quantitative data shows that the ratio of total chloroplast area to mesophyll cell area is constant across different cells within a single species, and also across species. Wild-type chloroplasts exhibit little scatter around this trend; highly irregularly-shaped mutant chloroplasts exhibit

Chloroplasts extend stromules independently and in response to internal redox signals

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2015
Significance Chloroplasts are critical, dynamic organelles in plant cells responsible for photosynthesis and myriad other aspects of metabolism. In recent years, plant cell biologists have increasingly focused on the formation of thin, long extensions ...

Photoinduced electron transfer across phospholipid bilayers in anaerobic and aerobic atmospheres

open access: yesAngewandte Chemie International Edition, Accepted Article.
In natural photosynthesis, light‐driven electron transfer across the thylakoid membrane enables efficient charge separation and the confinement of reaction spaces for generating NADPH and CO2 and oxidation of water. These reactions are complementary redox reactions and require different reaction conditions for optimal performance.

Not All Light Spectra Were Created Equal: Can We Harvest Light for Optimum Food‐Energy Co‐Generation?

open access: yesEarth's Future, Volume 10, Issue 12, December 2022., 2022
Abstract Humanity's growing appetites for food and energy are placing unprecedented yield targets on our lands. Chasing those ever‐expanding land intensification targets gave rise to monocultures and sharpened the divide between food and energy production groups.

Salinity Induces Granal Development in Bundle Sheath Chloroplasts of NADP-Malic Enzyme Type C4 Plants

open access: yesPlant Production Science, 2009
In NADP-malic enzyme (NADP-ME) type C4 plants, MC chloroplasts have well-developed grana, whereas BSC chloroplasts are generally characterized by highly reduced grana.

REDIdb 3.0: A Comprehensive Collection of RNA Editing Events in Plant Organellar Genomes

open access: yesFrontiers in Plant Science, 2018
RNA editing is an important epigenetic mechanism by which genome-encoded transcripts are modified by substitutions, insertions and/or deletions. It was first discovered in kinetoplastid protozoa followed by its reporting in a wide range of organisms.

Toc75‐V/OEP80 is processed during translocation into chloroplasts, and the membrane‐embedded form exposes its POTRA domain to the intermembrane space

open access: yesFEBS Open Bio, 2020
The insertion of membrane proteins requires proteinaceous complexes in the cytoplasm, the membrane, and the lumen of organelles. Most of the required complexes have been described, while the components for insertion of β‐barrel‐type proteins into the ...

Gene Similarity-based Approaches for Determining Core-Genes of Chloroplasts [PDF]

open access: yes, 2014
In computational biology and bioinformatics, the manner to understand evolution processes within various related organisms paid a lot of attention these last decades. However, accurate methodologies are still needed to discover genes content evolution. In a previous work, two novel approaches based on sequence similarities and genes features have been ...

Assessing the efficiency of ethyl acetate for lipid extraction as an alternative to the Folch method in selected marine low‐trophic species

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
The EtOAc method offers a straightforward and environmentally friendly protocol for lipid extraction, showing efficiency comparable to the Folch method, particularly in extracting lipids with high proportions of neutral lipids and free fatty acids. Abstract The recognized health benefits associated with marine omega‐3 polyunsaturated fatty acids (PUFAs)

Salinity Stress Induces Granal Development in Bundle Sheath Chloroplasts of Maize, an NADP-Malic Enzyme-Type C4 Plant

open access: yesPlant Production Science, 2006
Zea mays is an NADP-malic enzyme (ME)-type C4 plant. The C4 plants of this type are attractive species for ultrastructural and physiological studies because they possess reduced grana in bundle sheath cell (BSC) chloroplasts.
