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 ...

An optimized protocol for the preparation of oxygen-evolving thylakoid membranes from Cyclotella meneghiniana provides a tool for the investigation of diatom plastidic electron transport

BMC Plant Biology, 2017
Background The preparation of functional thylakoid membranes from diatoms with a silica cell wall is still a largely unsolved challenge. Therefore, an optimized protocol for the isolation of oxygen evolving thylakoid membranes of the centric diatom ...

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,

Quantifying and monitoring functional Photosystem II and the stoichiometry of the two photosystems in leaf segments: Approaches and approximations [PDF]

, 2015
Given its unique function in light-induced water oxidation and its susceptibility to photoinactivation during photosynthesis, photosystem II (PS II) is often the focus of studies of photosynthetic structure and function, particularly in environmental

Transmission electron microscopy characterisation of Spirulina bioplastics

Journal of Microscopy, EarlyView.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

Photosystems activities and polypeptide composition of Cyamopsis tetragonoloba and Vigna mungo thylakoids as affected by exclusion of solar UV radiation

Biologia Plantarum, 2010
The impacts of solar UV (280-400 nm) radiation on photosynthetic activities and polypeptide composition of thylakoids of cluster bean (Cyamopsis tetragonoloba L, UV-B sensitive) and black gram (Vigna mungo L., UV-B resistant) plants were compared.

Epitypification of Merismopedia tranquilla (Cyanobacteria) prompts phylogenetic reassessment of the genus and the description of two morphologically similar genera

Journal of Phycology, EarlyView.
Abstract The genus Merismopedia is morphologically characterized by its distinctive colony arrangement yet exhibits considerable variability among species. Recent studies suggested that Merismopedia is polyphyletic, and its most likely true lineage was provisionally placed within the Microcystaceae. However, the available molecular data for most of the

Biogenesis and origin of thylakoid membranes

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2001
Thylakoids are photosynthetically active membranes found in Cyanobacteria and chloroplasts. It is likely that they originated in photosynthetic bacteria, probably in close connection to the occurrence of photosystem II and oxygenic photosynthesis. In higher plants, chloroplasts develop from undifferentiated proplastids.

Effects of TROL Presequence Mutagenesis on Its Import and Dual Localization in Chloroplasts [PDF]

, 2018
Thylakoid rhodanase-like protein (TROL) is involved in the final step of photosynthetic electron transport from ferredoxin to ferredoxin: NADP+ oxidoreductase (FNR).
