mrt-2 encodes a highly conserved DNA-damage checkpoint protein homologous to the RAD1 protein found in S. pombe, Drosophila, and mammals; mrt-2 functions in the germline to maintain chromosomal integrity, and promote cell cycle arrest in mitotic germ cells and apoptosis in meiotic germ cells in response to genotoxic agents (DNA damage); mrt-2 mutations result in progressive telomere loss, chromosome fusion, and aneuploidy, eventually leading to germline mortality; MRT-2 interacts with HUS-1 and HPR-9, also conserved DNA-damage checkpoint proteins.
Caenorhabditis elegans

Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.

BACKGROUND: Understanding gene function and genetic relationships is fundamental to our efforts to better understand biological systems. Previous studies systematically describing genetic interactions on a global scale have either focused on core biological processes in protozoans or surveyed catastrophic interactions in metazoans. Here, we describe a reliable high-throughput approach capable of revealing both weak and strong genetic interactions in the ... [more]

Additional Notes

  • A systematic genetic interaction analysis (SGI) was carried out to detect interactions between 11 query mutants and 858 target genes compromised by RNA interference (RNAi). Interactions were determined using growth scores that indicated whether the resulting number of progeny from the double mutant was significantly different than that of single mutant controls.
