Hexaploid bread wheat (Triticum aestivum L. em. Thell) is one of the world's most important crop plants and displays a very low level of intraspecific polymorphism. We report the development of highly polymorphic microsatellite markers using procedures optimized for the large wheat genome. The isolation of microsatellite-containing clones from(More)
A lipoxygenase preparation was obtained from green algae Oscillatoria sp. and was shown to differ from previous described lipoxygenases in the positional specificity and pH characteristics of the dioxygenation reaction. The enzyme had a pH optimum at 8.8 and was inactive at pH 6. Oscillatoria lipoxygenase converted linoleic acid into two products:(More)
In France, the national computerized program for sow herd management regularly delivers a listing of hypoprolific boars for which a cytogenetic evaluation is required, and participates in the differential diagnosis of the other causes of reduced prolificacy. Two reciprocal translocations, 4/14 and 7/15, reducing the prolificacy by about 45 percent have been(More)
Une nouvelle translocation réciproque t, rcq (7 q-15 q+) a été identifiée chez un verrat dont la prolificité apparaît réduite de 45 p. 100.! Les conséquences zootechniques et économiques de cette anomalie sont discutées. Summary A new type of reciprocal translocation in a hypoprolific boar : t, rcp (7 q-; 15 q +) A new type of reciprocal translocation t,(More)
In the control and the surveillance of fast breeder reactors, high temperature fission chambers able to operate in extremes of temperature and gamma dose perform two essential functions: • In-vessel integrated neutronic control; • Clad failure detection by integrated detectors. In addition, they can be used for example to: • Measure the weight of the(More)
Monolayer cultures of MCF-7 human breast cancer cell line were treated with arachidonic acid (AA) and 15-L-(s)-hydroperoxyeicosatetraenoic acid (15-L-(s)-HPETE) in a concentration range of 10(-5)-10(-11) M and their relative cytotoxic potential was determined. Both compounds had a time and dose-dependent cytotoxic effect on MCF-7 cells. 15-L-(S)-HPETE, the(More)
During germination the chestnut (Castanea sativa L.) var ecotype 33 accumulates a large amount of asparagine in the cotyledons. This compound also accumulates in the growing axis:shoots and roots. In the cotyledons, gamma-aminobutyrate (GABA) represents a major amino compound during germination and early seedling growth. In young seedlings, 35 days old,(More)
Genetic trends for growth and carcass traits were estimated in the Large White (LW) and French Landrace (FL) pig breeds, using the records of 7529 LW and 4118 FL gilts reared in progeny-test stations between 1970 and 1981, and 34887 LW and 16779 FL boars reared in performance-test stations between 1969 and 1981. Three methods of estimation were used. Method(More)
