The Hidden Architects: Nitric Oxide and Redox Dynamics in Plant Stem Cell Homeostasis

BioEssays, EarlyView.
This review highlights the dynamic interplay between nitric oxide (NO) and reactive oxygen species (ROS) in regulating plant stem cell renewal and differentiation. NO and ROS integrate intrinsic factors like epigenetic and hormonal signals with extrinsic cues, including environmental stress and nutrient‐TOR signaling, to maintain meristem function and ...

Antiaging, Wound‐Healing Properties and Chemical Characterization of Crude Hydroalcoholic Extract and Fractions of Myrcia neoobscura

Chemistry &Biodiversity, EarlyView.
ABSTRACT The aim of this study was to characterize the phytochemical profile and potential antiaging and wound‐healing activities of 70% hydroalcoholic crude extract (CHE) from Myrcia neoobscura leaves and its fractions—insoluble (IF), ethyl acetate (EAF), and aqueous (AF)—for use in phytocosmetics for skin application.

Response of date palm offshoots (Phoenix dactylifera L.) to the foliar spray of salicylic acid and citric acid under salinity conditions

Folia Oecologica, 2022
Antioxidants enhance the salt tolerance of date palms. A field experiment was carried out on date palm offshoots to improve the salt tolerance of the Sayer cultivar. Salicylic acid and citric acid (500 and 1,000 ppm) were used.

Abscisic Acid Transport in Human Erythrocytes [PDF]

Journal of Biological Chemistry, 2015
Abscisic acid (ABA) is a plant hormone involved in the response to environmental stress. Recently, ABA has been shown to be present and active also in mammals, where it stimulates the functional activity of innate immune cells, of mesenchymal and hemopoietic stem cells, and insulin-releasing pancreatic β-cells.

Development and Recent Advances in SLIPT‐PM: A Chemogenetic Platform for Manipulating Signaling at the Plasma Membrane

ChemBioChem, EarlyView.
SLIPT‐PM enables the translocation of tag‐fused proteins from the cytoplasm to the plasma membrane using a synthetic self‐localizing ligand. This user‐friendly system permits reversible control of diverse signaling pathways. This concept article highlights the key features and current applications of SLIPT‐PM as a powerful tool in chemical and ...

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

METTL5‐mediated 18S rRNA m6A modification enhances ribosome assembly and ABA response in Arabidopsis

iMeta, EarlyView.
METTL5 catalyzes the N6‐methyladenosine (m6A) methylation at A1771 in 18S rRNA, a modification essential for its association with the ribosomal protein RPL24A, facilitating the assembly of 80S ribosome. This facilitates the translation of mRNAs encoding the detoxifying glutathione S‐transferase (GST) enzymes, thereby maintaining normal reactive oxygen ...
