    Genetic mapping of arg, cpa, car and tsm genes in Saccharomyces cerevisiae by trisomic analysis (1982)
    Springer
    Current genetics 6 (1982), S. 93-98

    Notes: Summary By use of a set of 8 aneuploid strains of the yeast Saccharomyces cerevisiae, carrying from 1 to 5 identified disomic chromosomes, in crosses to a set of haploid strains collectively bearing 11 unmapped genes, the following chromosome assignments were obtained for these unmapped genes: arg80 on XIII;arg3 on X;car2 on XII; cpa1 and tsm8740 on XV; tsm7269 (=rna6) on II; cpa2 on X or XV; arg82 and tsm4572 on III, IV or XVI; car1 and arg81 on II, IV, VI, VII or XVI. Linkage tests between the unmapped genes and markers located on the chromosomes that had been designated as possible carriers by the previous analysis allowed 8 genes to be localized. The remaining three genes, cpa2, car1 and arg81 (located on fragment F8), could not be positioned on any of the chromosomes indicated by the trisomic analysis, in spite of testing for linkage to markers covering most of the known regions of these chromosomes.

    Description / Table of Contents: Summary Experimental study, by means of leaf analysis, on the deficiency of nitrogen, phosphorus, potassium, calcium, sulphur, molybdenum, in a series of African soils. The plants were the arachide, the oilpalm and the coconut-tree. By the optimum of fertilization, the action of correspondent mineral fertilizers was determined.
    Abstract: Zusammenfassung Experimentelle Untersuchung, mittels Blattanalyse, über Mangel an Stickstoff, Phosphor, Kalium, Calcium, Schwefel, Molybdän, in einer Anzahl afrikanischer Böden, die zur Kultur von Erdnuss, Oelpalme, Cocospalme dienen. Wirkung der entsprechenden Mineraldünger zur Beseitigung der Nährstoffmängel und Bestimmung des Düngeroptimums.

    Le cycle biologique deHolorchis pycnoporus M. Stossich, 1901 (Trematoda, Lepocreadiidae) (1978)

    Description / Table of Contents: Résumé Les auteurs décrivent en détail les différents stades du cycle biologique du générotypeHolorchis pycnoporus M. Stossich, 1901. Les rédies de première générotions parasitent la glande génitale deBarleeia rubra (Adams) (Prosobranche marin, Rissoidea). Les cercaires, du type ophtalmotrichocerque, sont pondues tôt et mûrissent en dehors des rédies filles. Quelques cercaires s'enkystent sur place, dans la gonade du premier hôte.B. rubra joue donc à la fois le rôle de premier et de deuxième hôte. La majorité des cercaires est libérée dans le milieu extérieur. Les cercaires s'enkystent dansParvicardium papillosum (Poli) (Lamellibranche, Cardiidae). Les vers adultes ont été obtenus expérimentalement chezDiplodus sargus etD. annularis (Téléostéens, Sparidae). Le milieu dans lequel se déroule le cycle biologique est précisé. La diagnose du genreHolorchis est émendée et sa place dans la famille des Lepocreadiidae W. Nicoll, 1935 est discutée.
    Notes: Summary The life0cycle of the digenetic trematodeHolorchis pycnoporus M. Stossich, 1901 is described. The redial stages (first generation redia and daughter rediae) occur throughout the genital gland ofBarleeia rubra (Adams) a marine Prosobranch (Rissoidea). When cercariae leave rediae, they are not fully developed; the development is completed outside redia, within snail tissues, among rediae. Cercariae belong to the ophthalmotrichocercous group. Some cercariae encyst in situ, within genital gland tissues of the first intermediate host. Thus,B. rubra acts as first and second intermediate host. Almost all cercariae leave the molluscan host and are free swimming larvae; they penetrate the second host,Parvicardium papillosum (Bivalvia, Cardiidae) and develop into encysted metacercariae. Experimental development of metacercariae into adults have been obtained inDiplodus sargus andD. annularis (Teleostei, Sparidae). The habitat where the cycle is involved is described. The generic diagnosis ofHolorchis is emended; the place of this genus in Lepocreadiidae W. Nicoll, 1935 is discussed.
