The function of epithelial cell sheets depends on the integrity of specialized cell-cell junctions that connect neighbouring cells. We have characterized the novel coiled-coil protein AJM-1, which localizes to an apical junctional domain of Caenorhabditis elegans epithelia basal to the HMR-HMP (cadherin-catenin) complex. In the absence of AJM-1, the(More)
The 1.6 kb Tc1 transposable element of Caenorhabditis elegans undergoes excision and transposition in the germline. In somatic tissue it is excised at high frequency. Extrachromosomal linear and circular copies of Tc1 have been identified that are likely to be products of somatic and germline excision. In the present study, we have determined the sequences(More)
Punctodera punctata completed its life cycle on Poa annua (annual bluegrass), P. pratensis (Merion Kentucky bluegrass), Lolium perenne (perennial ryegrass), and Festuca rubra rubra (spreading fescue). Minimum time for completion of a life cycle from second-stage juvenile to mature brown cyst was 40 days at 22-28 C. Inoculation by single juveniles indicated(More)
