Genomic prediction of growth and wood quality traits in Eucalyptus benthamii using different genomic models and variable SNP genoty** density
Genomic selection (GS) is poised to revolutionize eucalypt tree improvement by shortening breeding cycles and increasing selection intensities. This could be particularly valuable for alternative, non-mainstream

Genomic relationship–based genetic parameters and prospects of genomic selection for growth and wood quality traits in Eucalyptus benthamii
The unique adaptation of Eucalyptus benthamii to low temperatures coupled to fast growth and versatile wood quality has made it a valued plantation species in frost-prone areas worldwide, but little is known on i...

Open AccessPests, diseases, and aridity have shaped the genome of Corymbia citriodora
Corymbia citriodora is a member of the predominantly Southern Hemisphere Myrtaceae family, which includes the eucalypts (Eucalyptus, Corymbia and Angophora; ~800 species). Corymbia is grown for timber, pulp and p...

Enviromics in breeding: applications and perspectives on envirotypic-assisted selection
We propose the application of enviromics to breeding practice, by which the similarity among sites assessed on an “omics” scale of environmental attributes drives the prediction of unobserved genotype performa...

Chloroplast genome assembly of Handroanthus impetiginosus: comparative analysis and molecular evolution in Bignoniaceae
Bignoniaceae species have conserved chloroplast structure, with hotspots of nucleotide diversity. Several genes are under positive selection, and can be targets for evolutionary studies.

Open AccessA genome-wide scan shows evidence for local adaptation in a widespread keystone Neotropical forest tree
The role of natural selection in sha** patterns of diversity is still poorly understood in the Neotropics. We carried out the first genome-wide population genomics study in a Neotropical tree, Handroanthus impe...

Near-infrared-based models for lignin syringyl/guaiacyl ratio of Eucalyptus benthamii and E. pellita using a streamlined thioacidolysis procedure as the reference method
Lignin syringyl/guaiacyl (S/G) ratio is a key trait in the cellulose pul** industry. Near-infrared (NIR) spectroscopy data collected with a bench and a portable instrument were used to develop prediction models...

Annotation of the Corymbia terpene synthase gene family shows broad conservation but dynamic evolution of physical clusters relative to Eucalyptus
Terpenes are economically and ecologically important phytochemicals. Their synthesis is controlled by the terpene synthase (TPS) gene family, which is highly diversified throughout the plant kingdom. The plant fa...

Status and Perspectives of Genomic Selection in Forest Tree Breeding
Trees have long life cycles and become reproductively active only after several years. The progress of tree breeding programs is therefore strongly dependent on the time needed to complete a breeding generatio...
