The plastome of land plants is often considered to be highly conserved in sequence,
structure, and content. This is particularly true for nonvascular land plants, for which few …

Background Although draft genomes are available for most agronomically important plant
species, the majority are incomplete, highly fragmented, and often riddled with assembly …

In recent years, the use of molecular data in algal systematics has increased as high-
throughput sequencing (HTS) has become more accessible, generating very large datasets …

Ferns, with about 12,000 species, are the second most diverse lineage of vascular plants
after angiosperms. They have been the subject of numerous molecular phylogenetic studies …

Background Ferns, originated about 360 million years ago, are the sister group of seed
plants. Despite the remarkable progress in our understanding of fern phylogeny, with …

Comprising about 82% of the extant fern species diversity, Polypodiales are generally
believed to have diversified in the Late Cretaceous. We estimated the divergence times of …

Ferns account for 80% of nonflowering vascular plant species and are the sister lineage of
seed plants. Recent molecular phylogenetics have greatly advanced understanding of fern …

We reconstructed a phylogenetic tree of Chinese vascular plants (Tracheophyta) using
sequences of the chloroplast genes atpB, matK, ndhF, and rbcL and mitochondrial matR. We …

The eupolypods II ferns represent a classic case of evolutionary radiation and,
simultaneously, exhibit high substitution rate heterogeneity. These factors have been …

Comprising more than 25 000 species, the Sunflower Family (Compositae or Asteraceae) is
the largest family of flowering plants. Many of its lineages have experienced recent and …
