A Phase‐Separated SR Protein Reprograms Host Pre‐mRNA Splicing to Enhance Disease Susceptibility

Advanced Science, EarlyView.
This study identifies SR30, a splicing factor, as a negative regulator of tomato immunity. During Phytophthora infestans infection, the elevated SR30 forms nuclear condensates to suppress the alternative splicing (AS) of defense‐related genes in a phase separation manner.

Spectroscopic Observations of the Recurrent Symbiotic Nova V407 Cyg During 2001 - 2009

Open Astronomy, 2012
We analyze the results of our spectroscopic monitoring of V407 Cyg in 2001–2009. the slow decline in optical brightness connected with the evolution of a Z And-type outburst (maximum in 1998) was observed in 2001–2003.

An X-Ray Jet from a White Dwarf - Detection of the Collimated Outflow from CH Cygni with Chandra

, 2004
Most symbiotic stars consist of a white dwarf accreting material from the wind of a red giant. An increasing number of these objects have been found to produce jets.

Genomes of coral dinoflagellate symbionts highlight evolutionary adaptations conducive to a symbiotic lifestyle

Scientific Reports, 2016
Despite half a century of research, the biology of dinoflagellates remains enigmatic: they defy many functional and genetic traits attributed to typical eukaryotic cells.

Hosts and Commensal Bacteria Synergistically Antagonize Opportunistic Pathogens at the Single‐Cell Resolution

Advanced Science, EarlyView.
In the tripartite‐species model, Drosophila larvae stimulate lactate production through excreting digestion enzymes. S. marcescens population senses a cue of lactate and tends to diverge into virulent and reduced virulence subclusters with remarkable heterogeneity to metabolize carbon metabolism and counter colonization resistance, giving a fitness ...

Differential gene expression analysis of symbiotic and aposymbiotic Exaiptasia anemones under immune challenge with Vibrio coralliilyticus

Ecology and Evolution, 2019
Anthozoans are a class of Cnidarians that includes scleractinian corals, anemones, and their relatives. Despite a global rise in disease epizootics impacting scleractinian corals, little is known about the immune response of this key group of ...

Ionization structure of hot components in symbiotic binaries during active phases

, 2012
During active phases of symbiotic binaries, an optically thick medium in the form of a flared disk develops around their hot stars. During quiescent phases, this structure is not evident.

Bacteroides Fragilis‐Derived Outer Membrane Vesicles Deliver MiR‐5119 and Alleviate Colitis by Targeting PD‐L1 to Inhibit GSDMD‐Mediated Neutrophil Extracellular Trap Formation

Advanced Science, EarlyView.
Bacteroides fragilis‐derived outer membrane vesicles deliver miR‐5119 and alleviate colitis by targeting PD‐L1 to inhibit GSDMD‐mediated neutrophil extracellular trap formation. Abstract Inflammatory bowel disease (IBD) results from a breakdown in the symbiotic relationship between the intestinal commensal microflora and the mucosal immune system.

The X-Ray Evolution of the Symbiotic Star V407 Cyg During its 2010 Outburst

Open Astronomy, 2012
We present a summary of Swift and Suzaku X-ray observations of the 2010 nova outburst of the symbiotic star, V407 Cyg. the Suzaku spectrum obtained on day 30 indicates the presence of the supersoft component from the white dwarf surface, as well as ...

Discovery in IC10 of the farthest known symbiotic star

, 2008
We report the discovery of the first known symbiotic star in IC10, a starburst galaxy belonging to the Local Group, at a distance of ~750kpc. The symbiotic star was identified during a survey of emission-line objects.
