Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

open access: yesJournal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Drought and salinity stress remodel Asian rice (Oryza sativa) leaf development through cell‐type‐specific regulatory programs

open access: yesNew Phytologist, EarlyView.
Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...

Identification and roles of Photosystem II assembly, stability, and repair factors in Arabidopsis

open access: yesFrontiers in Plant Science, 2016
Photosystem II (PSII) is a multi-component pigment-protein complex that is responsible for water splitting, oxygen evolution, and plastoquinone reduction.

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Molecular Chaperone Networks in Plants: Maintaining Proteostasis and Enhancing Stress Resilience for Crop Improvement

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Molecular chaperones play a central role in the plant proteostasis machinery by aiding the folding of nascent proteins, preventing aggregation, and repairing or degrading damaged proteins. These functions are especially essential during abiotic and biotic stress, which can destabilise cellular proteins and disrupt metabolic homoeostasis.

Tomato B cell receptor-associated protein 31 homologs enhance thermotolerance by promoting chloroplast PSBW accumulation and stabilizing the PSII–LHCII complex

open access: yesPlant Communications
B-cell receptor-associated protein 31 (BAP31) is an endoplasmic reticulum (ER) transmembrane protein in humans that regulates protein trafficking, apoptosis, and inflammatory responses to maintain cellular homeostasis. However, its role in plants remains

Quantitation of Cytochromes b559, b6, and f, and the Core Component of Photosystem I P700 in Cyanobacterial Cells

open access: yesBio-Protocol, 2016
Cytochrome (Cyt) b559, an important and essential core component of photosystem II in the photosynthetic electron transport system, is a heme-bridged heterodimer protein composed of an alpha subunit (PsbE) and a beta subunit (PsbE), and its reduced form ...

Specific association of photosystem II and light-harvesting complex II in partially solubilized photosystem II membranes. [PDF]

open access: yes, 1998
In this study, we report the structural characterization of photosystem II complexes obtained from partially solubilized photosystem II membranes. Direct observation by electron microscopy, within a few minutes after a mild disruption of the membranes ...

Daily Heat Stress Induces Donor‐Side Limitation of PSI Via Downregulation of the Cyt b6f Complex

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The rapidly warming climate is driving increasingly frequent and intense heat waves worldwide, posing major challenges to plant metabolism and growth. Despite the central role of photosynthesis in plant growth, the effects of prolonged heat stress on the primary reactions of photosynthesis remain poorly understood.
