Highlights•Post-polyploid diploidization (PPD) in angiosperms usually operates by
descending dysploidy.•PPD is acting with differing intensities and rates.•Multiple base …

Gymnosperms represent an ancient lineage that diverged from early spermatophytes during
the Devonian. The long fossil records and low diversity in living species prove their complex …

We assembled the 9.8-Gbp genome of western redcedar (WRC; Thuja plicata), an
ecologically and economically important conifer species of the Cupressaceae. The genome …

Background Genomic selection (GS) is a promising approach for decreasing breeding cycle
length in forest trees. Assessment of progeny performance and of the prediction accuracy of …

Hybridization and polyploidy followed by genome‐wide diploidization had a significant
impact on the diversification of land plants. The ancient At‐α whole‐genome duplication …

Plant mitogenomes can be difficult to assemble because they are structurally dynamic and
prone to intergenomic DNA transfers, leading to the unusual situation where an organelle …

We developed the densest single-nucleotide polymorphism (SNP)-based linkage genetic
map to date for the genus Quercus. An 8k gene-based SNP array was used to genotype …

Over the last decade, extensive genetic and genomic resources have been developed for
the conifer white spruce (Picea glauca, Pinaceae), which has one of the largest plant …

In species with large and complex genomes such as conifers, dense linkage maps are a
useful resource for supporting genome assembly and laying the genomic groundwork at the …

Norway spruce (Picea abies (L.) Karst.) is a conifer species of substanital economic and
ecological importance. In common with most conifers, the P. abies genome is very large (∼ …
