Competence for chemical reprogramming of sexual fate correlates with an intersexual molecular signature in Caenorhabditis elegans.

abstract：:A major correlation has been found between the incidence of glucocorticoid-induced cleft palate and the chromosome 8 segment identified by N-acetyl transferase in mice. The resistant strain became fully susceptible while the susceptible strain became resistant when this chromosomal region, representing less than 0.7% ...

Filamentous fungi, such as Neurospora crassa, depend on communication to locate compatible cells, coordinate cell fusion, and establish a robust hyphal network. Two MAP kinase (MAPK) pathways are essential for communicat...
