Phylogenetic reconstruction is fundamental to study evolutionary biology and historical biogeography. However, there was not a molecular phylogeny of gymnosperms represented by extensive sampling at the genus level, and most published phylogenies of this group were constructed based on cytoplasmic DNA markers and/or the multi-copy nuclear ribosomal DNA. In this study, we use LFY and NLY, two single-copy nuclear genes that originated from an ancient gene duplication in the ancestor of seed…

Early genome duplications in conifers and other seed plants
Analysis of transcriptomes from 24 gymnosperms and 3 outgroups indicates that polyploidy has contributed to the evolution of conifers and other gymnos perms, contrary to previous genomic research that reported an absence of polyploidsy in the ancestry of contemporary gymnOSperms.
Plastome phylogenomic analysis of Torreya (Taxaceae)
Phylogenetic inference using a maximum likelihood framework resolved Torreya as a monophyletic clade and strong supported relationships within the genus include the position of the early diverging T. jackii Chun, the two sister pairs T. and T. grandis Fortune ex Lindl.–T.
From America to Eurasia: a multigenomes history of the genus Abies.
Phylogenetics of extant and fossil Pinaceae: methods for increasing topological stability1
The tree topologies from parsimony and Bayesian inference confirm previous findings that the fossil genus Pseudoaraucaria and a few species of Pityostrobus from the Lower Cretaceous are related to abietoid genera, and that other species of...
The complete mitochondrial genome of Taxus cuspidata (Taxaceae): eight protein-coding genes have transferred to the nuclear genome
The results revealed the diversity in size, structure, gene and intron contents, foreign sequences, and mutation rates of gymnospermMitogenomes, which are different from angiosperm mitogenomes.
Retrotransposon distribution and copy number variation in gymnosperm genomes
Investigation of distantly related gymnosperm species reveals persistent RE sequences, such as IFG and Pineywoods, distributed among a wide range of plant lineages, which could have similar patterns or distribution of these elements.
Molecular evolution and SSRs analysis based on the chloroplast genome of Callitropsis funebris
Next‐generation sequencing technology was used to sequence the complete chloroplast genome of Callitropsis funebris and then constructed the phylogenetic relationship between Ca.
Revisiting the Plastid Phylogenomics of Pinaceae with Two Complete Plastomes of Pseudolarix and Tsuga
From the 65 plastid protein-coding genes common to all Pinaceous genera, the phylogenetic relationship among all Pinassic genera is re-examined and a unique insertion of tandem repeats in accD of T. chinensis is reported.
Single-Copy Genes as Molecular Markers for Phylogenomic Studies in Seed Plants
This study identified single-copy genes in a broad collection of seed plants and used these to infer phylogenetic relationships between major seed plant taxa, and phylogenetic trees from concatenated alignments without 3rd codon positions and amino acid alignments under the CAT + GTR model support gnetophytes as a sister group to Pinaceae.


Phylogeny and divergence times in Pinaceae: evidence from three genomes.
Intergeneric relationships of Pinaceae using sequences of the chloroplast matK gene, the mitochondrial nad5 gene, and the low-copy nuclear gene 4CL are studied to suggest morphology of both vegetative and reproductive organs has undergone convergent evolution within the pine family.
Molecular phylogeny of extant gymnosperms and seed plant evolution: analysis of nuclear 18S rRNA sequences.
To study the evolutionary relationships among the four living gymnosperm orders and the interfamilial relationships in each order, a set of 65 nuclear 18S rRNA sequences from ferns, gymnosperms, and
Seed plant phylogeny inferred from all three plant genomes: monophyly of extant gymnosperms and origin of Gnetales from conifers.
The Gnetales may be viewed as extremely divergent conifers, and the many morphological similarities between angiosperms and G netales arose independently.
Highly conserved low-copy nuclear genes as effective markers for phylogenetic analyses in angiosperms.
These conserved universal nuclear genes have several inherent qualities enabling them to be good markers for reconstructing angiosperm phylogeny, even eukaryotic relationships, further providing new insights into the evolutionary history of angiosperms.
Evolution and biogeography of gymnosperms.
Systematic Error in Seed Plant Phylogenomics
It is shown that non-time reversible properties of aligned sequence positions in the chloroplast genomes of Gnetales mislead phylogenetic reconstruction of these seed plants, highlighting the importance of goodness of fit between substitution model and data for understanding seed plant phylogeny.
Phylogenetic relationships and divergence times of the family Araucariaceae based on the DNA sequences of eight genes
DNA sequences obtained from this study and GenBank were used for constructing the molecular phylogenetic trees of Araucariaceae, indicating that the phylogenetic relationships among the three genera of this family should be ((Wollemia, Agathis), Araucaria).
Loss of all plastid ndh genes in Gnetales and conifers: extent and evolutionary significance for the seed plant phylogeny
It is found that all ndh genes are absent across Gnetales and Pinaceae, but not in any other group of gymnosperms, providing additional support for the contentious “gnepine” hypothesis, which places G netales as sister to Pinaceae.
