Cycads represent one of the most ancient lineages of living seed plants. Identifying genomic
features uniquely shared by cycads and other extant seed plants, but not non-seed …

Background Cycads are ancient seed plants (living fossils) with origins in the Paleozoic.
Cycads are sometimes considered a'missing link'as they exhibit characteristics intermediate …

During the past few years several high-quality genomes has been published from
Charophyte algae, bryophytes, lycophytes and ferns. These genomes have not only …

Phylogenetic relationships among the 5 groups of extant seed plants are presently
unsettled. To reexamine this long-standing debate, we determine the complete chloroplast …

Phylogenetic reconstruction is fundamental to study evolutionary biology and historical
biogeography. However, there was not a molecular phylogeny of gymnosperms represented …

The extant seed plants include more than 260,000 species that belong to five main lineages:
angiosperms, conifers, cycads, Ginkgo, and gnetophytes. Despite tremendous effort using …

Ferns are the only major lineage of vascular plants not represented by a sequenced nuclear
genome. This lack of genome sequence information significantly impedes our ability to …

Y chromosomes carry genes with functions in male reproduction and often have few other
loci. Their evolution and the causes of genetic degeneration are of great interest. In addition …

We investigated higher-order relationships in the cycads, an ancient group of seed-bearing
plants, by examining a large portion of the chloroplast genome from seven species chosen …

Chloranthales remain the last major mesangiosperm lineage without a nuclear genome
assembly. We therefore assemble a high-quality chromosome-level genome of Chloranthus …
