The RALF1 peptide-FERONIA complex phosphorylates the endosomal sorting protein FREE1 to attenuate abscisic acid signaling.

The receptor-like kinase FERONIA (FER), together with its ligand rapid alkalinization factor 1 (RALF1) peptide, plays a crucial role in regulating stress responses, including its involvement in modulating abscisic acid (ABA) signaling. FER has been shown to activate ABA insensitive 2 in the cytoplasm, leading to the suppression of ABA signaling. However, its regulation of nucleus events in the ABA response remains unclear.

The FERONIA-RESPONSIVE TO DESICCATION 26 module regulates vascular immunity to Ralstonia solanacearum.

Some pathogens colonize plant leaves, but others invade the roots, including the vasculature, causing severe disease symptoms. Plant innate immunity has been extensively studied in leaf pathosystems; however, the precise regulation of immunity against vascular pathogens remains largely unexplored. We previously demonstrated that loss of function of the receptor kinase FERONIA (FER) increases plant resistance to the typical vascular bacterial pathogen Ralstonia solanacearum.

Osteoinductive micro-nano guided bone regeneration membrane for in situ bone defect repair.

Background: Biomaterials used in bone tissue engineering must fulfill the requirements of osteoconduction, osteoinduction, and osseointegration. However, biomaterials with good osteoconductive properties face several challenges, including inadequate vascularization, limited osteoinduction and barrier ability, as well as the potential to trigger immune and inflammatory responses. Therefore, there is an urgent need to develop guided bone regeneration membranes as a crucial component of tissue engineering strategies for repairing bone defects.

ZIF-8 induced hydroxyapatite-like crystals enabled superior osteogenic ability of MEW printing PCL scaffolds.

ZIF-8 may experience ion-responsive degradation in ionic solutions, which will change its initial architecture and restrict its direct biological use. Herein, we report an abnormal phenomenon in which ZIF-8 induces large hydroxyapatite-like crystals when soaked directly in simulated body fluid. These crystals grew rapidly continuously for two weeks, with the volume increasing by over 10 folds.

A unique van Hove singularity in kagome superconductor CsVTaSb with enhanced superconductivity.

Van Hove singularity (VHS) has been considered as a driving source for unconventional superconductivity. A VHS in two-dimensional (2D) materials consists of a saddle point connecting electron-like and hole-like bands. In a rare case, when a VHS appears at Fermi level, both electron-like and hole-like conduction can coexist, giving rise to an enhanced density of states as well as an attractive component of Coulomb interaction for unconventional electronic pairing.
