    Cellular localisation of the clamp protein during DNA replication (2002)

    Notes: The β subunit of Escherichia coli DNA polymerase III holoenzyme was fused to the green fluorescent protein GFP. The gene fusion under the control of the heterologous lac promoter was used to replace the wild-type allele in the chromosome. The formation of GFP-β fluorescent foci in GFP-β expressing cells required DNA replication and their number per cell was dependent on cell growth. Examination of GFP-β foci in a synchronous round of replication suggested that DNA replication was accompanied by the recruitment of GFP-β foci near the midcell, followed by the rapid migration of the foci in opposite directions to the 1/4 and 3/4 positions during DNA replication.

    Characterization of a new Bacillus thuringiensis endotoxin, Cry47Aa, from strains that are toxic to the Australian sheep blowfly, Lucilia cuprina (2005)

    Notes: Sixteen isolates of Bacillus thuringiensis, derived from various soil samples collected in Australia, are highly toxic to larvae of the sheep blowfly (Lucilia cuprina). The toxin gene from one of the strains (CAA890) was cloned by genome walking, and sequencing of the cloned fragments revealed a new cry gene, encoding a protein of 1134 amino acid residues, with a theoretical molecular mass of 139,209 Da. Based on the amino acid sequence comparison with known Cry δ-endotoxins, the gene was designated cry47Aa. Homology modelling based on known crystal structures of the Cry toxins reveals the differences to be located in the loops of domain II in the putative toxin-receptor binding surfaces between Cry47Aa and the dipteran active Cry2Aa. We also showed that the cry47Aa gene is present in the other isolates that are highly toxic to the sheep blowfly.

    A Drosophila Minute gene encodes a ribosomal protein (1985)

    Notes: [Auszug] rp49 was mapped by in situ hybridization to the chromosomal region 99D (rf. 10), near the previously described Minute (3)1. Although M(3)l has recently been mapped more precisely to 99B5-9 (rf. 13), distinct from the position of rp499 we have used the following genetic approach and identified a ...

    A survey of C-band patterns in chromosomes ofLilium (Liliaceae) (1989)
    Springer
    Plant systematics and evolution 163 (1989), S. 53-69

    Notes: Abstract C-band patterns are described for 20Lilium spp. distributed across six sections. All species have a similar basic karyotype (n = 12) but C-bands differ markedly between them. The patterns are characterized by a dispersed scattering of thin intercalary bands as well as centric and NOR bands. Only one species,L. canadense, shows a clear equilocal pattern with intercalary C-bands occurring proximally in all of the longer chromosome arms. Comparing species, similar patterns are revealed forL. regale andL. sulphureum, forL. formosanum andL. longiflorum (all in sect.Leucolirion) and to a lesser extent forL. hansonii, L. martagon, andL. tsingtauense (sect.Martagon). The pattern forL. henryi (previously classed in sect.Sinomartagon) matches those ofL. regale andL. sulphureum quite well and its transfer to sect.Leucolirion is proposed. This is consistent with results from interspecies hybrids betweenL. henryi andL. regale (and related species) which are reportedly fertile. No other clear similarities in C-band patterns were seen across species. It seems that C-band patterns change rapidly inLilium and hence their usefulness in classification will be restricted to identifying closely related species.

    Use of λgt11 and monoclonal antibodies to map the gene for the 60,000 dalton glycoprotein of infectious laryngotracheitis virus (1993)

    Notes: Abstract To localize the gene encoding the 60 kD glycoprotein (gp60) of infectious laryngotracheitis virus (ILTV), a library of the ILTV genome was constructed in the λgt11 expression vector. Twelve recombinant bacteriophages expressing gp60 epitopes as fusion products with β-galactosidase were detected by immunoscreening with monoclonal antibodies specific for gp60. The ILTV DNA sequence contained in one of these recombinants λ24-4 was used as a hybridization probe for mapping the insert sequence on the viral genome. The gene for the gp60 was located at map unit 0.72–0.77 in the unique long region (UL) of the ILTV genome. The DNA sequence of the 1.2 kb insert of λ24-4 containing the gp60 epitope was determined. The majority of deduced gp60 amino acid sequence has no homology with any of the known alphaherpesvirus glycoproteins.
