In a large group of fungi, mating results in a dikaryon, a cell in which the two nuclei-one from
each parent cell-share a single cytoplasm for a period of time without undergoing nuclear …

In the phytopathogenic fungus Ustilago maydis, the dikaryotic state dominates the period of
growth occurring during the infectious phase. Dikaryons are cells in which two nuclei, one …

During induction of the virulence program in the phytopathogenic fungus Ustilago maydis,
the cell cycle is arrested on the plant surface and it is not resumed until the fungus enters the …

DNA damage response (DDR) leads to DNA repair, and depending on the extent of the
damage, to further events, including cell death. Evidence suggests that cell differentiation …

Chk1 is a protein kinase that acts as a key signal transducer within the complex network
responsible of the cellular response to different DNA damages. It is a conserved element …

The fungal fruiting body or mushroom is a multicellular structure essential for sexual
reproduction. It is composed of dikaryotic cells that contain one haploid nucleus from each …

The regulation of cyclin-dependent kinase (CDK) activity through inhibitory phosphorylation
seems to play an important role in the eukaryotic cell cycle. We have investigated the …

Ustilago maydis is a plant pathogen that requires a specific structure called infective filament
to penetrate the plant tissue. Although able to grow, this filament is cell cycle arrested on the …

It is widely accepted that MAPK activation in budding and fission yeasts is often associated
with negative effects on cell cycle progression, resulting in delay or arrest at a specific stage …

Plant pathogenic fungi often developed specialized infection structures to breach the outer
surface of a host plant. These structures, called appressoria, lead the invasion of the plant by …
