Sequence-tagged-site (STS) markers of arbitrary genes: the amount and nature of variation revealed in Norway spruce
Article Abstract:
Sequence-tagged-site (STS) markers of arbitrary genes are discussed as applied to the nature and amount of variation in Norway spruce. Variation was studied by cDNA-based sequence-tagged-site (STS) markers. Polymorphisms at one STS locus indicate a higher affinity is likely between Norway spruce and white spruce than between either of those and black spruce. Twenty-two trees each from a differemt provenance with a different European area of origin were used in test plantations near Quebec City in Canada.

Differentiation between clonal growth and limited gene flow using spatial autocorrelation of microsatellites
Article Abstract:
Limited gene flow and differentiation between clonal growth are discussed relative to a study using spatial autocorrelation of microsatellites. Distribution of seven microsatellite loci representing 37 alleles in a 10 x 80 m plot of a perennial population of eelgrass Zostera marina L. was studied. Results show the need for an a priori estimation of genet-ramet structure in clonally reproducing plants to get away from invalid inferences about putative gene flow with varying spatial scales.

Pollination in the marine realm: microsatellites reveal high outcrossing rates and multiple paternity in eelgrass Zostera marina
Article Abstract:
Microsatellites have shown high outcrossing rates and multiple paternity in Zostera marina in investigation of pollination in the marine world. Outcrossing could be seen from the presence of nonmaternal alleles at one or more loci where multilocus genotyping was used with microsatellite DNA markers. The coefficient of relatedness was determined in sibships. PCR-based methods were found to allow detection of pollen origin early in progeny development.
