Cell division machinery mapped
Ghent University researchers have succeeded in mapping the complex interactions between proteins that underlie plant cell division. Using what they describe as a targeted proteomics approach, the researchers generated a map of the complex of core genes controlling the cell cycle in Arabidopsis thaliana. They also identified protein networks that link the core cell cycle machinery to up- and down-stream pathways. More than 100 previously unknown proteins linked to cell division were identified during the four-year project.
