    Notes: Agriculture has evolved independently in three insect orders: once in ants, once in termites, and seven times in ambrosia beetles. Although these insect farmers are in some ways quite different from each other, in many more ways they are remarkably similar, suggesting convergent evolution. All propagate their cultivars as clonal monocultures within their nests and, in most cases, clonally across many farmer generations as well. Long-term clonal monoculture presents special problems for disease control, but insect farmers have evolved a combination of strategies to manage crop diseases: They (a) sequester their gardens from the environment; (b) monitor gardens intensively, controlling pathogens early in disease outbreaks; (c) occasionally access population-level reservoirs of genetically variable cultivars, even while propagating clonal monocultures across many farmer generations; and (d) manage, in addition to the primary cultivars, an array of "auxiliary" microbes providing disease suppression and other services. Rather than growing a single cultivar solely for nutrition, insect farmers appear to cultivate, and possibly "artificially select" for, integrated crop-microbe consortia. Indeed, crop domestication in the context of coevolving and codomesticated microbial consortia may explain the 50-million year old agricultural success of insect farmers.

    Notes: Über die Aufnahme der Jesus-Überlieferung im frühen Christentum ist schon viel nachgedacht und geschrieben worden. Dabei interessiert das Problem meist wegen des auffallenden Sachverhaltes, daß Pauls allenfalls dreimal ausdrücklich auf Herrenworte zurückgreift (I Kor 7, 10; 9, 14; vgl. I These 4, 15), wobei I These 4, 15 ohne erkennbare synoptische Parallele ist. Verschärft ist dieser Sachverhalt noch dadurch, daß Pauls speziell im I Kor offen zugeben kann, kein Jesuswort zur Regelung von Gemeindeverhält-nissen zu besitzen (7, 12. 25. 40).

    High resolution replication patterns of the human Y chromosome (1982)

    Notes: Abstract Replication studies on prophasic human Y chromosomes reveal 4 early replicating segments in the euchromatic portion. The distal segment of Yp replicates first. After replication of the euchromatic part is almost finished 3 to 5 segments start replication in the heterochromatic portion of Yq. These segments exhibit considerable intraindividual variation with respect to the origin of onset of replication. While the location of these bands — once they are differentiated — is fixed within one individual, the number of these bands varies interindividually.

    Immunological and functional aspects of H-Y antigen (1981)
    Springer

    Notes: Summary Male-specific H-Y antigen may be defined by graft rejection, killer cell action or antibodies. Most commonly H-Y antigen is detected in assays using H-Y antisera. In these tests errors may arise from various causes: 1) Auto- and heteroantibodies cross-reacting with target cells. 2) Restriction phenomena. 3) MHC-dependent modification of the amount of H-Y antigen present on different tissues. 4) Modification of cell surface antigens by bacteria or viruses. Regarding the third definition of H-Y antigen, four different “states” can be distinguished in the mammalian male. H-Y occurs (1) as an integral part of the plasma membrane; (2) unspecifically attached to the membrane of human erythrocytes; (3) free in solution; (4) bound to its gonad-specific receptor. Redistribution experiments suggest that H-Y and β 2-m are associated on the cell membrane. Coredistribution is not found of H-Y and MHC antigens. An antibody blocking technique demonstrates association of H-Y and H-2D antigens on unfixed lymphoid, but not on testicular cells. Human erythrocytes lacking β 2-m do not integrate H-Y antigen into the cell membrane. Male erythrocytes, however, absorb H-Y antigen from the serum. The origin of H-Y antigen in the serum is not clear. It may be shed from cell membranes, derive from the testis which actively secretes H-Y antigen, or both. H-Y antigen is bound by a gonad-specific receptor. This receptor is present in the gonads of both sexes. H-Y antigen is supposed to mediate testis differentiation via this receptor. Reaggregation experiments in vitro using dissociated gonads of the newborn rat demonstrate that ovarian cells reorganize into testicular structures in the presence of H-Y antigen. The assumption cannot be confirmed that addition of H-Y antiserum to testicular cells results in ovarian structures. This finding, however, does not conflict with the view that H-Y antigen is involved in testis differentiation, e.g. by inducing testis cell-specific functions via the gonad-specific receptor.

    Homologous early replication patterns of the distal short arms of prometaphasic X and Y chromosomes (1982)

    Notes: Summary Replication studies on prometaphasic human sex chromosomes reveal a distinct early replicating segment on both distal Xp and Yp. These segments correspond to high resolution bands Xp22.3 and Yp11.3. The findings demonstrate synchronous replication of these parts of the sex chromosomes and correspond to the comparatively long stretches of Xp and Yp that participate in a synaptonemal complex. Furthermore these observations are compatible with Polani's view that suggests homologous segments with similar genetic information on both sex chromosomes (Polani 1982).
