Common Names: Norway spruce
Researchers studied genetic markers related to circadian and growth rhythms in Norway spruce trees. They found SNPs correlated with elevation and health condition, including genes involved in redox homeostasis and disease resistance. This study enhances understanding of local adaptation in Norway spruce populations.
This study examines CNV of defense genes in conifers against insects, using a probe set to measure gene copy numbers. Results shed light on the constitutive defense mechanisms in white spruce. Further research on CNV emergence and phenotype effects is suggested.
Resin-based otic rinse from Norway spruce could help treat canine ear infections. However, its antimicrobial effectiveness against dog pathogens and potential harm to the ears is unknown.
Branchwood samples near the stem have extractives similar to knots, making them a potential source of knotwood for biorefinery. Douglas fir knotwood has strong antioxidant activity, while silver fir and spruce knotwood have high antibacterial activity due to flavonoids and lignans.
Genome sequencing of 25 Norway spruce individuals shows limited selection in coding regions and a correlation between adaptive substitutions and recombination rate, highlighting natural selection's role in shaping the species' genomic architecture. Specific targeted molecular functions and biological processes of selection were also identified.
