Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

The FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Ubiquitin and ubiquitin‐like modifications in the endoplasmic reticulum stress response

The FEBS Journal, EarlyView.
Endoplasmic reticulum (ER) stress activates various proteostasis control processes, including the unfolded protein response, ribosome‐associated quality control, and ER‐associated degradation. Ubiquitin and ubiquitin‐like modifications dynamically regulate these processes to determine cell fate, promoting adaptation or inducing cell death.

Dual IRE1 targets: Determinants of the cell fate?

The FEBS Journal, EarlyView.
IRE1 is an ER stress sensor that restores protein homeostasis through two signaling activities: XBP1s, which upregulates its target gene expression or RIDD which downregulates its target transcripts. We recently identified Dual IRE1 Targets (DIT) which are modulated by both XBP1s and RIDD activities.

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

New Phytologist, EarlyView.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Protective Effect of Curcumin on the Tight Junction Integrity and Cellular Senescence in Human Retinal Pigment Epithelium of Early Diabetic Retinopathy

Journal of Physiological Investigation
Diabetic retinopathy (DR) is a secondary complication of diabetes that can lead to visual impairment and blindness. The retinal pigment epithelium (RPE) is a monolayer of pigment cells that forms the blood–retinal barrier (BRB) via tight junction (TJ ...

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

New Phytologist, EarlyView.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

Endophytic and Rhizospheric Actinobacteria from Guiera senegalensis as Novel Sources of Glucose Isomerase under Submerged Fermentation

UMYU Scientifica Journal
Glucose isomerase (GI) is a key industrial enzyme used to convert glucose to fructose in the production of high-fructose corn syrup (HFCS). Despite the widespread application of GI, there is a growing need to explore novel and cost-effective microbial ...
