Postglacial colonization of brown trout in Europe based on distribution of allozyme variants

Article Abstract:

Colonization of brown trout in the postglacial period has been studied through distribution of allozyme variants in Europe. Fourteen published studies and unpublished data were used to compile data from 11 polymorphic allozyme loci. Three preglacial lineages existed, each fixed for different sets of alleles at the two loci, LDH-C and CK-A1. At the time of glacial retreat, recolonization seems to have taken place mostly into adjacent areas. A northern expansion from an Atlantic drainages refuge may have taken place in southern France and Iberia, and perhaps there was a northern/eastern radiation from a refuge near the English Channel and a north-western migration from an eastern Mediterranean-Caspian area refuge.

Population genetic structure of European hake, Merluccius merluccius

Article Abstract:

In allozyme analysis of tissue samples of 910 European hake, Merluccius merluccius, polymorphism was found at 21 of 34 protein-coding loci. The samples were from six North Atlantic and four Mediterranean locations. A major subdivision was seen from allelic differences related to the two collections. Gene flow from nearby Atlantic to proximal Mediterranean populations was suggested by allele frequencies and relevant oceanographic and geological information. Present management, based on two distinct populations, is justified. The differing and separate northern and southern stocks suggested by the International Council for the Exploration of the Sea (ICES) do not constitute an adequate description.

RFLP markers associated with major genes controlling heading date evaluated in a barley germ plasm pool

Article Abstract:

Results show that restriction fragment length polymorphism (RFLP) markers associated with major genes are maintained in a germ plasm pool of 32 barley cultivars. Data also indicate that RFLP markers are useful tools in germ plasm characterization and marker-assisted selection in breeding programs.
