Notizen: Summary We have constructed and analysed somatic cell hybrids from cell lines containing balanced reciprocal translocations involving chromosome 19 and providing two new breakpoints on 19q. These and other hybrids have been tested with a series of markers from 19q to enhance the existing map. Several new cloned DNA sequences that map to 19q13.3–19qter are reported; the locus D19Z1 has been analysed by CHEF gel electrophoresis.

Notizen: Abstract The total dissolved load of the Rhine river increases downstream due to the combined impact of natural and pollution loads. The natural background, controlled by geology, is soon swamped by pollution, particularly from salt and coal mining activities in Alsace and the Ruhr area. The Rhine is also a net source of CO2 from oxidation of excess organic productivity that is fuelled by nutrient pollution, a problem even more serious for some of its tributaries.

Notizen: Abstract Electrical discharge particle acceleration was used to test the transient expression of numerous inducible angiosperm promoters in a gymnospermPicea glauca (white spruce). Promoter expression was assayed in three different tissues capable ofin vitro regeneration, zygotic embryos, seedlings and embryogenic callus. The promoters tested include the light-inducibleArabidopsis and soybean ribulose-1,5-bisphosphate small subunit promoters and a maize phosphoenolpyruvate carboxylase promoter; a soybean heat-shock-inducible promoter, a soybean auxin inducible promoter and a maize alcohol dehydrogenase promoter. Promoters were cloned into a promoter-less expression vector to form a promoter-β-glucuronidase-nopaline synthase 3′ fusion. A similar construct was made using the cauliflower mosaic virus 35S (CaMV 35S) promoter as a control. All promoters were expressed in white spruce embryos, yet at levels lower than CaMV 35S. In addition, in the embryos the heat-shock and the alcohol dehydrogenase promoters showed inducible expression when given the proper induction stimulus. In seedlings, expression of all promoters was lower than in the embryos and expression was only inducible with the heat-shock promoter in the cotyledons. Of the tissues tested, the expression level of all promoters was lowest in embryogenic callus. Interestingly, the expression of the β-glucuronidase gene in embryogenic callus was restricted to the proembryonal head cells regardless of the promoter used. These results clearly demonstrate the use of particle bombardment to test the transient expression of heterologous promoters in organized tissue and the expression of angiosperm promoters in a gymnosperm.

Thema: Biologie

Notizen: Summary An RFLP-based genetic map of Secale Cereale has provided evidence for multiple evolutionary translocations in the rye genome relative to that of hexaploid wheat. DNA clones which have previously been mapped in wheat indicated that chromosome arms 2RS, 3RL, 4RL, 5RL, 6RS, 6RL, 7RS and 7RL have all been involved in at least one translocation. A possible evolutionary pathway, which accounts for the present day R genome relative to the A, B and D genomes of wheat, is presented. The relevance of these results for strategies designed to transfer useful genes from rye, and probably other related species, to wheat is discussed.

Notizen: Abstract In order to test gas-phase reaction schemes for the production of small oxides of carbon in cold, dense interstellar clouds, we have searched for the radical CCO and for propadienone (H2C3O) in Taurus Molecular Cloud 1, a nearby cloud which exhibits a rich organic chemistry. The radical CCO has been detected with a fractional abundance some two orders of magnitude less than that of CCS, about one order of magnitude less than that of H2CCO, and slightly less than that of C3O. An upper limit has been obtained on the abundance of propadienone which is slightly less than that of its isomer propynal (HC2CHO).

Notizen: Abstract An instrument for neutron capture prompt gamma-ray activation analysis (PGAA) has been constructed as part of the Cold Neutron Research Facility at the 20 MW National Institute of Standards and Technology Research Reactor. The neutron fluence rate (thermal equivalent) is 1.5·108 n ·cm−2·s−1, with negligible fast neutrons and gamma-rays. With compact geometry and hydrogen-free construction, the sensitivity is sevenfold better than an existing thermal instrument. Hydrogen background is thirtyfold lower.

Notizen: Abstract An Accelerator Mass Spectrometry (AMS) facility has been assembled at the University of North Texas (UNT) in collaboration with Texas Instruments, Inc. The UNT AMS facility is used primarily for the high sensitivity determination of trace elements of stable isotopes in materials. Particle accelerators, in conjunction with magnetic (momentum/charge) and electrostatic (energy/charge) spectrometers and particle energy detectors, may be used to measure rare isotopes at concentrations as low as one part in 1012 or 1010 atoms/cm3.
