“…As shown previously with other molecular markers [allozymes (Lagercrantz and Ryman 1990), AFLP (Acheré et al 2005), and cytoplasmic DNA Sperisen et al 2001)], the Norway spruce population is today genetically and geographically divided into two main domains, namely the Baltico-Nordic domain and the Alpine Central European domain, and a more limited one, the Carpathian domain, represented in the present survey by a single population, Romania. This population had a very limited polymorphism and may not be representative of the Carpathian domain.…”

Multilocus Patterns of Nucleotide Diversity, Linkage Disequilibrium and Demographic History of Norway Spruce [Picea abies (L.) Karst]

et al. 2006

DNA polymorphism at 22 loci was studied in an average of 47 Norway spruce [Picea abies (L.) Karst.] haplotypes sampled in seven populations representative of the natural range. The overall nucleotide variation was limited, being lower than that observed in most plant species so far studied. Linkage disequilibrium was also restricted and did not extend beyond a few hundred base pairs. All populations, with the exception of the Romanian population, could be divided into two main domains, a BalticoNordic and an Alpine one. Mean Tajima's D and Fay and Wu's H across loci were both negative, indicating the presence of an excess of both rare and high-frequency-derived variants compared to the expected frequency spectrum in a standard neutral model. Multilocus neutrality tests based on D and H led to the rejection of the standard neutral model and exponential growth in the whole population as well as in the two main domains. On the other hand, in all three cases the data are compatible with a severe bottleneck occurring some hundreds of thousands of years ago. Hence, demographic departures from equilibrium expectations and population structure will have to be accounted for when detecting selection at candidate genes and in association mapping studies, respectively.

“…The identification of genes related to local adaptation and differentiation is also essential for the conservation of local populations. However, such genes have only been identified in model plants to date (for a review, see Shimizu and Purugganan, 2005), although genomic regions associated with speciation and population differentiation have been reported in several forest tree species, including Quercus and Picea abies (Scotti-Saintagne et al, 2004;Acheré et al, 2005). Thus, there is an urgent need to extend the identification of such genes to the genomes of other species to facilitate conservation efforts.…”

Genetic diversity and the genetic structure of natural populations of Chamaecyparis obtusa: implications for management and conservation

et al. 2007

We investigated 25 natural populations of Chamaecyparis obtusa using 51 cleaved amplified polymorphic sequence (CAPS) markers, which were developed using information on sequence-tagged sites (STS) in Cryptomeria japonica. Most CAPS markers have codominant expression patterns, and are suitable for population studies because of their robustness and convenience. We estimated various genetic diversity parameters, including average heterozygosity (H e ) and allelic richness and found that the more peripheral populations tended to have lower genetic diversity than central populations, in agreement with a previous theoretical study. The overall genetic differentiation between populations was low, but statistically significant (G ST ¼ 0.039), and similar to the level reported in a previous allozyme study. We attempted to detect non-neutral loci associated with local adaptation to clarify the relationship between the fixation index (F ST ) and H e values for each locus and found seven candidates non-neutral loci. Phylogenetic tree analysis of the populations and Bayesian clustering analysis revealed a pattern of gradually increasing isolation of populations with increasing geographical distance. Three populations had a high degree of linkage disequilibrium, which we attribute to severe bottlenecks due to human disturbance or competition with other species during their migration from refugia after the most recent glaciation. We concluded that the small populations in western Japan and in Kanto district are more important, from a conservation perspective, than the populations in central Japan, due to their genetic divergence, relatively small sizes and restricted areas.

“…The number of alleles per locus obtained in this research is lower than those described by other authors for P. abies. Acheré et al (2005) found alleles per locus for the 25 microsatellites studied in the range of 5-55 (25 in average). Maghuly et al (2006) detected 27 (in average) alleles within five loci.…”

“…Individual samples from each of the six locations are dispersed throughout the entire dendrogram because of the large intrapopulation variability. Several studies have shown that genetic variation is relatively high and that the majority is partitioned within (rather than between) populations (Cottrell et al 2003;Acheré et al 2005). Maghuly et al (2006) analyzed genetic diversity in different subpopulations of Norway spruce in Austria by nuclear SSRs finding more genetic variation and heterozygosity within populations than among populations.…”

“…Genetic variability of P. abies from different populations in Europe has been previously investigated by means of several markers (Acheré et al 2005;Goncharenko et al 2005;Maghuly et al 2006;La Porta et al 2007). Also microsatellites, as markers especially suitable for studies of tree population genetics, have already been applied to highlight differences among populations (Scotti et al 2000(Scotti et al , 2002.…”

Differences in wood properties of Picea abies L. Karst. in relation to site of provenance and population genetics Abstract: Chemical and physical characteristics of wood from six European populations of Picea abies were investigated taking into consideration their genetic differentiation determined by four microsatellites markers. The growth conditions of investigated spruce trees differed significantly. As a consequence, several adaptations were observed in samples from varying environments. The adaptation mechanisms include a variation to the annual rings morphology as well as the physical properties of the wood. It was proved that some properties, such as wood density or latewood ratio, are strictly correlated to the environmental variables. Results show that trees from geographically distinct populations present some diversity in the genotypes. It was also noticed that some trees did not share their genetic profile with other plants from the same location due to high intrapopulation variability. Samples from Finland possessed the lowest level of internal differentiation, while samples from northern Poland presented the lowest allele richness and were most divergent from the others. It was not possible to correlate any wood properties (chemical or physical) to genetic features of the population due to high intrapopulation diversity.
