“…In the research of genetic variability of eight natural populations of Abies nephrolepis Max. using SSR markers in Korea the small genetic distances (average 0.027) have been determined, indicating that populations are closely related and that there is a free exchange of genes between them (WOO et al, 2008).…”

The paper presents the results of the analysis of genetic variability of eight populations of silver fir (Abies alba Mill.) in Serbia obtained using SSR markers. The genomic DNA was isolated from tissue of needles of all eight populations. Due to the costly and lengthy process a small number of the SSR markers for Abies alba have been developed, so in this study were used the microsatellite markers of related species. The obtained results indicate a low level of the genetic variability between natural populations of silver fir. The total number of alleles detected with nine SSR markers in eight studied populations of silver fir is 28. The range of alleles varies from two for NFF15 to six for SF78 with an average of 3.1 alleles per locus. The mean value of genetic similarity between populations is 0.92. The smallest genetic similarity between pairs of populations is 0.82 (Dubočica Bare and Stara Planina; Dubočica Bare and Tara) and the greatest genetic similarity is 1 (Zlatar and Stara Planina, Zlatar and Tara, Stara Planina and Tara). A basic insight into the level of genetic diversity of natural populations of silver fir in Serbia, which are located in a relatively small area, has been given using a set of SSR markers. The obtained results can be used in the future strategy for the management and regeneration of silver fir forests.

“…This value was significantly higher than that found in the same species using isozymes (12.5%, Scaltsoyiannes et al 1999) and similar to that detected in P. pinea (97.0%, Alvarez et al, 2004). The mean genetic diversity (H e = 0.379) was higher than the detected in the same species (H e = 0.010) using isozymes (Scaltsoyiannes et al, 1999) Hamrick and Godt, 1990;Woo et al, 2008). However, most of the available population genetic data in the species are based on other markers, which may be the reason why the values are not comparable with our results.…”

Abstract• The Spanish fir (Abies pinsapo Boiss.) is a conifer endemic to southern Spain and belongs to a Mediterranean basin group of firs considered to be relict. Megagametophyte storage proteins are a useful tool for the evaluation of genetic variability due to the haploid nature of megagametophytes in conifers.• In this paper, we report for the first time, the usefulness of megagametophyte storage proteins marker in A. pinsapo as a first investigation of the level of genetic diversity conserved in the extant stands of this relict conifer. For this, four populations were analysed from the three areas in which the species is still found. A total of thirty trees and ten megagametophytes per tree were analysed. In addition, 191 megagametophytes from two trees were assessed to identify polymorphic bands and to confirm Mendelian inheritance 1:1.• Albumins have proved to be a good marker to assess the genetic variability in this species, due to their high level of variation. Fourteen polymorphic bands adjusted to the expected 1:1 segregation ratio, two cases of allelism and eight of linkage were detected.• The genetic diversity study showed that, in the four populations, approximately half of the genetic diversity was among trees and the other half among seeds of each tree. Differentiation between populations was less than 6.0%. Results from this study could be useful for determining appropriate conservation management strategies for this endangered species.

“…However, a disadvantage of this technique is the dominant character of the obtained products. Despite this disadvantage, the ISSR technique has been used to determine the level of genetic diversity in many forest tree species of the genera Abies [38], Pinus [4,[39][40][41], Picea [42], Pseudotsuga [43], Taxus [44], Fagus [45], Quercus [46], and others. There are, however, no studies on ISSR analysis in pitch pine.…”

Genetic variability in pitch pine (Pinus rigida Mill.) growing in the Niepołomice Forest as determined by ISSR markers

et al. 2018

The study aimed to determine the genetic variability in pitch pine (<em>Pinus rigida</em> Mill.) growing in the Niepołomice Forest (southern Poland). In the late nineteenth and early twentieth century, Adolf Cieślar of the Department of Forestry Research in Mariabrunn near Vienna, Austria established the experimental crops of pitch pine. During the study, 227 trees that grew in seven subunits were considered; an analysis of genetic polymorphism using the intersimple sequence repeats (ISSR) technique revealed that pitch pine is genetically variable. The average number of alleles at a given locus for all the pine trees was 1.649, while the effective number of alleles at the loci was 1.435. The value of expected heterozygosity was 0.254, while the percentage of polymorphic loci was 75.30%. The average genetic distance between the examined pines was 0.082. Principal coordinate analysis (PCoA) divided the examined pines into three groups, which was also confirmed by the structure-analysis results of the software STRUCTURE. The resulting division was mainly generated by the SR70 primer, which was indicated to be the primer that differentiated the examined populations of pitch pine. Affiliation of particular trees to selected groups was based on their occurrence in individual crops. This suggests a different origin of the seeds used to establish the research plots of pitch pine in the Niepołomice Forest.
