Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

Fission yeast bub1 is a mitotic centromere protein essential for the spindle checkpoint and the preservation of correct ploidy through mitosis [PDF]

, 1998
The spindle checkpoint ensures proper chromosome segregation by delaying anaphase until all chromosomes are correctly attached to the mitotic spindle.

TED1 Promotes the Assembly of SCFD3‐D14‐D53 to Reinforce Strigolactone Signaling in Rice

Advanced Science, EarlyView.
This study identifies TED1 as a positive regulator of strigolactones (SL) signaling in rice. The ted1 mutants display dwarfism and increased tillering with significantly reduced SLs sensitivity. Through its longer C‐terminal region, TED1 interacts with D53 and D14 to promote the assembly of SCFD3‐D14‐D53, thereby facilitating the efficient ...

Meiotic nuclear divisions in budding yeast require PP2ACdc55-mediated antagonism of Net1 phosphorylation by Cdk [PDF]

, 2011
During meiosis, one round of deoxyribonucleic acid replication is followed by two rounds of nuclear division. In Saccharomyces cerevisiae, activation of the Cdc14 early anaphase release (FEAR) network is required for exit from meiosis I but does not lead

Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

Cytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The

Excessive rDNA Transcription Drives the Disruption in Nuclear Homeostasis during Entry into Senescence in Budding Yeast

Cell Reports, 2019
Summary: Budding yeast cells undergo a limited number of divisions before they enter senescence and die. Despite recent mechanistic advances, whether and how molecular events are temporally and causally linked during the transition to senescence remain ...

Photo Quiz: Globose Yeast‐Like Forms With Multiple Peripheral Buds in Urine and Cervical Cytology

Diagnostic Cytopathology, EarlyView.
ABSTRACT A 26‐year‐old immunocompetent woman with a history of noninvasive, low‐grade papillary urothelial carcinoma presented with persistent upper abdominal pain. Urine cytology, performed for bladder tumor surveillance, revealed globose, yeast‐like forms (10–30 μm) with thick walls and multiple narrowly attached peripheral buds in a “ship wheel ...
