Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

Iron deficiency in plants: an insight from proteomic approaches

Frontiers in Plant Science, 2013
Iron (Fe) deficiency chlorosis is a major nutritional disorder for crops growing in calcareous soils, and causes decreases in vegetative growth as well as marked yield and quality losses.

HSP90C interacts with PsbO1 and facilitates its thylakoid distribution from chloroplast stroma in Arabidopsis. [PDF]

PLoS ONE, 2017
Arabidopsis plastidic HSP90C is an HSP90 family molecular chaperone that is required for chloroplast development and function. To understand the mechanism of action of HSP90C within the chloroplast, we conducted a yeast two-hybrid screening and revealed ...

Evolution of Thylakoid Structural Diversity

Annual Review of Cell and Developmental Biology
Oxygenic photosynthesis evolved billions of years ago, becoming Earth's main source of biologically available carbon and atmospheric oxygen. Since then, phototrophic organisms have diversified from prokaryotic cyanobacteria into several distinct clades of eukaryotic algae and plants through endosymbiosis events.

SIB1‐SEC23A undergo ER to chloroplast relocalization to mediate immunity in Arabidopsis thaliana

Journal of Integrative Plant Biology, EarlyView.
SEC23A mediates membrane trafficking between the endoplasmic reticulum (ER) and Golgi apparatus and interacts with the immunity protein SIGMA FACTOR‐BINDING PROTEIN1 in Arabidopsis. Under stress, both proteins relocate from the ER to chloroplasts, suppressing photosynthesis genes and enhancing defense genes.

Coniferyl aldehyde from the phenylpropanoid pathway targets pyruvate kinase in Dactylobotrys graminicola to confer sheath rot resistance in hulless barley

Journal of Integrative Plant Biology, EarlyView.
Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...

STN7 operates in retrograde signalling through controlling redox balance in the electron transfer chain

Frontiers in Plant Science, 2012
Phosphorylation of the major photosynthetic light harvesting antenna proteins by STN7 kinase balances excitation between PSII and PSI. Phosphorylation of such abundant proteins is unique, differing distinctively from conventional tasks of protein kinases

Uncovering the role of the PPR protein PHOTOSYSTEM ONE BIOGENESIS FACTOR6 in splicing chloroplast group II introns

Journal of Integrative Plant Biology, EarlyView.
The P‐class pentatricopeptide repeat (PPR) protein PHOTOSYSTEM ONE BIOGENESIS FACTOR (PBF6) forms splicing complexes with other known splicing factors to facilitate chloroplast intron splicing. PBF6 cooperates with other PPR splicing factors to promote the splicing of the same intron through forming respective splicing complexes.

Advances in high‐resolution cryo‐volume electron microscopy (cvEM) imaging for unicellular and multicellular organisms

Journal of Microscopy, EarlyView.
Abstract Cryo‐Focused Ion Beam Scanning Electron Microscopy (cryoFIB‐SEM) using samples fixed by high‐pressure freezing uniquely enables high‐resolution cryo‐volume Electron Microscope (cvEM) images of cell ultrastructure to be obtained from whole cells and complex tissues in their near native state. As the freezing process also preserves fluorescence,

Uni‐site ATP synthesis in thylakoids

FEBS Letters, 1990
Uni‐site ATP synthesis was measured with thylakoids. The membrane‐bound ATP‐synthase, CF0F1 was brought into the active, reduced state by illumination in the presence of thioredoxin, dithiothreitol and phosphate. This enzyme contains two tightly bound ATP per CFoF1. ATP was released from the enzyme when ADP was added in substoichiometric amounts during
