Killer meiotic driver prevents chromosome loss and enhances fitness in a fungal pathogen

This study shows that the meiotic driver Spore Killer (spok) prevents chromosome loss and enhances fitness in the fungal pathogen Fusarium oxysporum by maintaining dispensable chromosomes during meiosis.

Condensin pinches a short negatively supercoiledDNA loop during each round of ATP usage

The paper shows condensin creates a short negatively supercoiled DNA loop during ATP usage, which may merge with an extruding loop.

FACT mediates cohesin function on chromatin

This study shows that FACT is required for cohesin stability on chromatin and the formation of cohesin-dependent TAD-like structures, but not sister chromatid cohesion.

PP4 phosphatase cooperates in recombinational DNA repair by enhancing double-strand break end resection

This study shows that PP4 phosphatase dephosphorylates Rad53, enhancing DNA end resection and recombinational repair by counteracting Rad9's inhibitory effect on Sgs1/Dna2.
