Dense vegetation as a natural buffer: Mitigating and decelerating drought propagation.

Effective management of soil drought requires a comprehensive understanding of drought propagation dynamics, particularly in the context of increasing vegetation. This study investigates the relationship between meteorological and soil droughts in the Red River Basin (RRB), Southwest China, using monthly Standardized Precipitation Evapotranspiration Index (SPEI) and Soil Moisture Index (SMI) data from 2000 to 2021. A novel peak backtracking method was developed to quantify key propagation metrics: propagation time (PT), triggering threshold (TR), and propagation rate (PR).

Lipid Droplet-Organized MDM2-Mediated P53 Degradation: A Metabolic Switch Governing Diet-Driven Tumor Progression.

TP53 inactivation in human cancers often results from MDM2/MDMX overexpression, yet therapeutic targeting remains challenging owing to incomplete mechanistic understanding. Lipid droplet (LD) enrichment is identified as a key trigger for MDM2-mediated p53 degradation. High-fat diet (HFD)-induced LD accumulation in tumor cells elevates LD-surface MDM2 through Cyb5r3-Myh9 interactions, which recruit cytoplasmic p53/Myh9 complexes to LDs.

The Arabidopsis NuA4 histone acetyltransferase complex is required for chlorophyll biosynthesis and photosynthesis.

Although two Enhancer of Polycomb-like proteins, EPL1A and EPL1B (EPL1A/B), are known to be conserved and characteristic subunits of the NuA4-type histone acetyltransferase complex in Arabidopsis thaliana, the biological function of EPL1A/B and the mechanism by which EPL1A/B function in the complex remain unknown. Here, we report that EPL1A/B are required for the histone acetyltransferase activity of the NuA4 complex on the nucleosomal histone H4 in vitro and for the enrichment of histone H4K5 acetylation at thousands of protein-coding genes in vivo. Our results suggest that EPL1A/B are required for linking the NuA4 catalytic subunits HISTONE ACETYLTRANSFERASE OF THE MYST FAMILY 1（HAM1) and HAM2 with accessory subunits in the NuA4 complex.
