“…It has been observed that a higher density of wood also implies greater natural durability [11]. Wood density is related to the structure of the cells of the vessels and the parenchyma [12], in which species resistant to cavitation have a greater density in the wood [13]. In this sense, density is positively correlated with tolerance to drought, so arid environments tend to be dominated by species with high wood density [13].…”

“…According to several authors, wood density is moderately to highly heritable in most forest species [10,14,15]. However, other studies have indicated that wood density can vary depending on local environmental conditions [13,16,17]. Bush et al [6] determined that the wood density of E. cladocalyx varies considerably based on the different regions of origin of the species, presenting moderate heritability (h 2 = 0.41).…”

Eucalyptus cladocalyx F. Muell is a tree species suitable for low-rainfall sites, even with annual average precipitation as low as 150 mm per year. Its wood is classified as highly durable and its permanence in soil is longer than 25 years, so it can be used for multiple applications. Given that about 41% of the world’s land area is classified as drylands, added to the impact of climate change on the availability of water resources, it becomes necessary to use plant species that can tolerate environments with low water availability. In this study, a Bayesian analysis of genetic parameters showed that wood density (WD) was moderately heritable, with a posterior mean of h2 = 0.29 and a Bayesian credibility region (90%) of 0.06–0.74, while the slenderness coefficient (SC) was highly heritable, with a posterior mean of h2 = 0.48 and a Bayesian credibility region (90%) of 0.11–0.87. Through Bayesian regression analysis, we identified four and three significant associations for WD and SC, respectively. Another important finding of the bi-trait Bayesian analysis was the detection of three large-effect pleiotropic QTLs located on LG4 at 52 cM, on LG2 at 125 cM, and on LG6 at 81 cM. Bayesian bi-trait regression and the posterior probability of association indicated that three QTLs presented strong evidence of association with WD and SC. This provides convincing evidence that the loci qtlWD130/qtlSC130, qtlWD195/qtlSC195, and qtlWD196/qtlSC196 have a significant pleiotropic effect. The association mapping based on multivariate Bayesian regression was useful for the identification of genomic regions with pleiotropic effects. These loci can be used in molecular marker-assisted breeding to select trees with better wood density.

“…Across a latitudinal gradient in Central America, patterns in wood density more strongly correlated to precipitation and aridity than temperature [21]. Wood density is positively associated with aridity in New Caledonia, and a global meta-analysis [22,23] suggests that high wood density is adaptive in dry environments. However, precipitation and temperature explain variation in tree height-diameter relationships across North America as well, possibly influencing wood density indirectly through structural constraints [24].…”

Research Highlights: To better understand within-community variation in wood density, our study demonstrated that a more nuanced approach is required beyond the climate–wood density correlations used in global analyses. Background and Objectives: Global meta-analyses have shown higher wood density is associated with higher temperatures and lower rainfall, while site-specific studies have explained variation in wood density with structural constraints and allometry. On a regional scale, uncertainty exists as to what extent climate and structural demands explain patterns in wood density. We explored the role of species climate niche, geofloristic history, habitat specialization, and allometry on wood density variation within a California forest/chaparral community. Materials and Methods: We collected data on species wood density, climate niche, geofloristic history, and riparian habitat specialization for 20 species of trees and shrubs in a California forest. Results: We found a negative relationship between wood density and basal diameter to height ratio for riparian species and no relationship for non-riparian species. In contrast to previous studies, we found that climate signals had weak relationships with wood density, except for a positive relationship between wood density and the dryness of a species’ wet range edge (species with drier wet range margins have higher wood density). Wood density, however, did not correlate with the aridity of species’ dry range margins. Geofloristic history had no direct effect on wood density or climate niche for modern California plant communities. Conclusions: Within a California plant community, allometry influences wood density for riparian specialists, but non-riparian plants are ‘overbuilt’ such that wood density is not related to canopy structure. Meanwhile, the relationship of wood density to species’ aridity niches challenges our classic assumptions about the adaptive significance of high wood density as a drought tolerance trait.

“…The aim of the provenance experiment is to select an excellent provenance of the trait of interest and then plant the selected elite provenance in a suitable ecological zone. Numerous studies indicated that many traits have extensive genetic differences between different provenances, such as the density fluctuations [ 1], the growth and stem formation [ 2], radial growth [ 3], terpenoid patterns in needles [ 4]. What's more, Brynjar Skulason et al found that subalpine fir (Abies lasiocarpa) provenances showed significant differences for all measured traits [ 5].…”

“…Some scholars believe that the differences between provenances are mainly determined by genetic factors [ 12,13], while others believe that differences between provenances are mainly caused by the environment, such as soil [ 14], climate [ 1,15,16], temperature [17][18][19], etc. In addition, the effects of nutrition on provenance growth have also been extensively studied.…”

Background The carbon fixation characteristic of F. mandshurica seedlings from 20 provenances has been evaluated by our research group. In order to explore whether growth and carbon sequestration are related to nutritional adaptability, the foliage and roots of the annual Wuchang (WC) seedlings with high carbon content and Hailin (HL) seedlings with low carbon content which were grown in nitrogen-deficient nutrition and total nutrition were used for RNA-seq determination. Results Eight transcriptome libraries by high-throughput sequence were analysis. 1,235,174,984 clean reads and 88,655 unigenes with N50 length of 1,259 bp were obtained. Under normal nitrogen condition, 783 differentially expressed genes (DEGs) between WC and HL were identified, the number in foliage (669) of DEGs between HL and WC was more than that in roots (149). The number of transcription factors (TFs), hormone, and Protein kinase (PK) genes was significantly more in WC than that in HL. Compared to the normal nitrogen, 8173 DEGs related to nitrogen deficiency were identified and the number of DEGs in roots (6999) was more than that in foliage (1616). Several nitrogen deficiency-related metabolic pathways and many DEGs involved in nitrogen absorption and assimilation, carbon metabolism, hormones, transcription factors and kinases were identified. The numbers of DEGs encoding nitrate transporters, PK, TFs and hormone in WC were less than that in HL, which indicated the response of HL provenance seedlings to nitrogen deficiency was stronger than that of WC provenance seedlings. However, under nitrogen deficiency, the number of up-regulated DEGs in the WC provenance seedlings is more than that in the HL, which indicated that the WC provenance seedlings were more tolerant to nitrogen deficiency than HL. Conclusions The data showed that high carbon content and high growth rate of WC provenance seedlings are mainly attributed to the high transcriptional expression of many metabolic genes in foliage. The response of HL provenance seedlings to nitrogen deficiency is significantly greater than that of WC provenances seedlings, but WC provenance seedlings were more tolerant to nitrogen deficiency than HL. Many genes related to nitrogen deficiency were identified, which will expand our current understanding of nitrogen responses.
