Special Issue Information

Dear Colleagues,

Adaptation to local environments will be a challenging issue for forests in the face of global climate changes. While other organisms have the choice of migrating to a better suited habitat, the current rate of climate change can be too fast for forest trees, which will have the only choice of locally adapting. Therefore, the knowledge of genetic adaptive traits is an essential support to actions in forest management and conservation.

Many approaches are now available to do this, from “classical” studies of association between some loci and environmental variables, carried also to a genomic scale by the use of SNPs arrays, to more sophisticated modeling, such as those used in landscape genetics/genomics, to Bayesian analyses aimed at unravelling the confounding effect of demography and population genetic structure, so as not to impact on the assessment of adaptive variation.

Further, information on the relationship between genetic variation and environmental variation is necessary to implement bioclimatic models to simulate how the present genetic variation will be shaped by a changing environment and to identify current and projected distribution of forest species. This aspect will also benefit from the validation of genetic and phenotypic associations under controlled environments.

The information obtained from different approaches can lead to the identification of genotypes adapted to future climatic conditions, to select seed sources and populations for planning sound conservation strategies like assisted migration or assisted range expansion, to help forest tree species to cope with fast-changing climatic conditions and prevent localized declines.

The threat to forests represented by imminent climate changes requires immediate countermeasures; because of this, we deem that a journal issue devoted to “Climate-Related Adaptive Genetic Variation and Population Structure in Forests” will be of general interest to many colleagues.

Research Highlights: Sequence phylogeny, genome organisation, gene structure, conserved motifs, promoter cis-element and expression profiling of poplar NACs related to salt stress were detected. In addition, expression of two salt-induced NACs was analysed. Background and Objectives: NAC transcription factor (TF) proteins are involved in a wide range of functions during plant development and stress-related endurance processes. To understand the function of Populus NAC TFs in salt stress tolerance, we characterised the structure and expression profile of a total of 289 NAC members. Materials and Methods: Sequence phylogeny, genome organisation, gene structure, motif composition and promoter cis-element were detected using bioinformatics. The expression pattern of Populus NAC TFs under salt stress was also detected using RNA-Seq and RT-qPCR. Results: Synteny analysis showed that 46 and 37 Populus NAC genes were involved in whole-genome duplication and tandem duplication events, respectively. The expression pattern of Populus NAC TFs under salt stress showed the expression of the 289 PtNACs of 84K poplar was induced. Similar expression trends of NACs were found in Populus simonii × P. nigra T. S. Hwang et Liang and Arabidopsis thaliana (L.) Heynh. Conclusions: The correlation analysis showed that the expression of two differentially expressed NAC genes PtNAC024 and PtNAC182 was significantly associated with most of the 63 differentially expressed genes tested. The expression of PtNAC024 and PtNAC182 in different tissues was also analysed in silico and different expression patterns were found. Together, this study provides a solid basis to explore stress-related NAC TF functions in Populus salt tolerance and development. Full article
