Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

Advanced Science, EarlyView.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Global Diversification Rates of Ferns Across Spatial and Climatic Gradients

Advanced Science, EarlyView.
Diversification rates of fern genera across the phylogeny. Abstract Geographic patterns of diversity in any group of plants are the result of the interplay of environmental conditions and the evolutionary dynamics of the respective plant group. Here, the geographic distribution of current mean diversification rates (MDR) is explored at the genus level ...

A low-cost flow cytometric assay for the detection and quantification of apoptosis using an anionic halogenated fluorescein dye

BioTechniques, 2008
We describe here a technical improvement of an established colorimetric method used to detect and measure the occurrence of apoptosis in mammalian cells during in vitro cell culture. This assay uses an anionic halogenated fluorescein dye that is taken up

Blocking Lysine Crotonylation and Aerobic Glycolysis as Targeting Strategy Against mpox Virus Replication

Advanced Science, EarlyView.
Wei et al. report that MPXV infection induces aerobic glycolysis, a process mediated by the viral protein I3 through lysine crotonylation at its K102 residue. The acetyltransferase MYST1 catalyzes the crotonylation of I3 to inhibit the ubiquitin‐mediated degradation of WDR26.
