Noncomplementing diploidy resulting from spontaneous zygogenesis in Escherichia coli

Microbiology, 2005
With the aim of understanding sexual reproduction and phenotypic expression, a novel type of mating recently discovered inEscherichia coliwas investigated. Termed spontaneous zygogenesis (or Z-mating), it differs from F-mediated conjugation. Its products proved phenotypically unstable, losing part of the phenotype for which they were selected ...

A Cdc2 dependent checkpoint maintains diploidy in Drosophila

Development, 1996
ABSTRACT DNA replication in G2 does not normally occur due to the checkpoint control. To elucidate its mechanism, the functions of the escargot and Dmcdc2 genes of Drosophila were studied. When escargot function was eliminated, diploid imaginal cells that were arrested in G2 lost Cyclin A, a regulatory subunit of G2/M cdk, and entered an
