Glu1, a conserved GH30_3 β-(1,6)-glucanase requires its catalytic residues for full virulence in Ustilago maydis

Perinuclear anchoring of telomeres enables plant infection by Ustilago maydis

This study shows that perinuclear telomere anchoring via Lem2 is essential for Ustilago maydis to infect plants, as its deletion disrupts nuclear migration and leads to infection failure.

A systematic quantitative approach comprehensively defines domain-specific functional pathways linked to Schizosaccharomyces pombe heterochromatin regulation

This study identifies domain-specific heterochromatin regulators in Schizosaccharomyces pombe using quantitative methods and genetic screening, revealing Dhm2's role in heterochromatin maintenance and replication fidelity.

Systematic characterization of Ustilago maydis sirtuins shows Sir2 as a modulator of pathogenic gene expression

The paper systematically studies sirtuins in Ustilago maydis, showing Sir2 modulates dimorphic switching and pathogenic development by repressing biotrophic gene expression without histone deacetylation.

The inner nuclear membrane protein Lem2 coordinates RNA degradation at the nuclear periphery

This study shows Lem2, an inner nuclear membrane protein in S. pombe, recruits exosome co-factors to the nuclear periphery to regulate RNA degradation and coordinate transcripts during the mitosis-to-meiosis switch.

Local chromatin context dictates the genetic determinants of the heterochromatin spreading reaction

The paper identifies gene regulators that influence heterochromatin spreading in different chromatin contexts using a fission yeast deletion library and sensor system.

Set1/COMPASS repels heterochromatin invasion at euchromatic sites by disrupting Suv39/Clr4 activity and nucleosome stability

The paper identifies a mechanism by which Set1/COMPASS prevents heterochromatin invasion at euchromatic sites through inhibition of Suv39/Clr4 and disruption of nucleosome stability.
