Targeted Capture

Conifer genomes are characterized by their large size and high abundance of repetitive material, making large-scale genotyping in conifers complicated and expensive. One of the consequences of this is that it has been difficult to generate data on genome-wide levels of genetic variation. To date, researchers have mainly employed various complexity reduction techniques to assess genetic variation across the genome in different conifer species. These methods tend to capture variation in a relatively small subset of a typical conifer genome and it is currently not clear how representative such results are. Here we take advantage of data generated in the first large-scale re-sequencing effort in Norway spruce and assess how well two commonly used complexity reduction methods, targeted capture probes and genotyping by sequencing perform in capturing genome-wide variation in Norway spruce. Our results suggest that both methods perform reasonably well for assessing genetic diversity and population structure in Norway spruce (Picea abies (L.) H. Karst.). Targeted capture probes were slightly more effective than GBS, likely due to them targeting known genomic regions whereas the GBS data contains a substantially greater fraction of repetitive regions, which sometimes can be problematic for assessing genetic diversity. In conclusion, both methods are useful for genotyping large numbers of samples and they greatly reduce the cost involved with genotyping a species with such a complex genome as Norway spruce.

The isoenzymatic studies performed on nine <em>Picea abies</em> H. Karst populations from Poland, indicated considerable genetic variation among investigated stands. Genetic similarities have demonstrated a clear pattern of geographic variability. Three of the nine studied populations (Zwierzyniec, Nowe Ramuki and Orawa) have shown markedly diverse characteristics compared to the remaining populations. The mountain populations have formed one group with two related subgroups. The mean number of alleles per locus (A / L = 2,22) and level of heterozygosity (Hp = 0,194) for the lowland populations are within the range of these parameters for other Norway spruce populations from Finland and Lithuania. The populations from Carpathians and Sudety mountains are geneticaly more polymorphic (Ho = 0,221, A / L = 2,34) than the others. This pattern of genetic variation suggests the existance of two gene pools, one from southern and one from northern Poland formed during the glacial period and differentiated further in southern Poland into two subpools.
