Special Issue Information

Dear Colleagues,

The rapid advancements in molecular genetics and genomics have significantly expanded our knowledge of forest tree genetic diversity, including genotype–phenotype relationships, species-specific genome characteristics, and adaptive capacity revealed through genetic monitoring. This knowledge is essential for understanding species adaptation mechanisms and their limits in response to environmental changes, particularly in the context of climate change and human-induced environmental degradation.

Despite accumulating genetic knowledge, gaps remain in forest tree genetics and gene conservation. While forest genetic resources have been identified and documented, questions persist regarding long-term conservation methods and optimal management. For example, the progress on genetic knowledge and information helped to understand that in situ conservation, previously considered sufficient, should be often combined with ex situ methods (dynamic conservation) for certain species. Likewise, the results of various genetic studies were successfully integrated to develop effective methods of forest ecosystem restoration.

The rational use of preserved genetic resources is crucial not only for the forestry sector's economy but also for restoring damaged ecosystems, adaptively maintaining forests, and sustainable landscape management. Enhancing our genetic knowledge and sharing practical conservation experiences will deepen our understanding of forest ecosystem complexity and the specific responses of tree species.

For this Special Issue, we encourage submissions that offer new findings or insights into forest genetics and the conservation and utilization of forest genetic resources.

Potential topics include, but are not limited to, the following:

  • Tree genetics and genomics;
  • Adaptation and resilience to changing environmental factors;
  • Genetic monitoring;
  • Conservation and the use of forest genetic resources;
  • The management of conservation units;
  • Genetic aspects linked to the restoration of forest ecosystems.

Forests in the Tolna region (Hungary) are distributed at the xeric limit of broadleaved forest zones and adapted to the arid ecological conditions of the wood-steppe climate. An 85-year-old in situ gene conservation stand of Quercus virgiliana mixed with other taxa of section Quercus was studied, which was regenerated naturally by both seedlings and coppicing. To analyze the phenotypes growing within the stand and the genetic structure of the population, a total of 138 trees were sampled. For taxonomic classification, a complex of morphological traits of oak taxa growing naturally in the region was used. Out of the 12 morphotype groups, only a few trees were classified as Q. virgiliana (eight individuals) or Q. robur (nine individuals), and the majority of the trees (121 individuals) were hybrid or introgressed phenotypes of Q. virgiliana adapted to xeric conditions by its xeromorphic traits. Despite the high number of coppiced trees (89 pcs vegetatively regenerated), the genetic variation was relatively high based on 16 nSSR markers used for analyses. Some of the trees were classified as non-autochthonous with Slavonian oak origin, both by morphological traits and SSR structure. Despite some alleles being lost, the allelic diversity of the seedling trees’ group was similar to that of the group of parent generation (coppiced trees). The spatial structure of trees supported the results of morphologic classification, and Q. virgiliana and hybrid phenotypes were growing on xeric microhabitats of the stand, mostly on southeast-facing slopes or ridges of hills. Consequently, the stand might fulfill all the in situ gene conservation requirements based on the high genetic diversity measured and the high number of xeromorphic phenotypes in the context of climate change as well.
