Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Replication fork stability is essential for the maintenance of centromere integrity in the absence of heterochromatin.

Li PC, Petreaca RC, Jensen A, Yuan JP, Green MD, Forsburg SL

The centromere of many eukaryotes contains highly repetitive sequences marked by methylation of histone H3K9 by Clr4(KMT1). This recruits multiple heterochromatin proteins, including Swi6 and Chp1, to form a rigid centromere and ensure accurate chromosome segregation. In the absence of heterochromatin, cells show an increased rate of recombination in the centromere, as well as chromosome loss. These defects are severely ... [more]
