Abstract This study reports the complete plastome sequence of Gnetum ula, a gymnosperm species of Gnetaceae (Gnetophyta). The plastome is 113 249 bp long. It has a quadripartite structure containing a pair of large inverted repeat regions of 19 772 bp each, a large single-copy region of 64 914 bp, and a small single-copy region of 8791 bp. One hundred sixteen genes were predicted in the plastome, including 68 protein-coding genes, eight ribosomal RNA genes, and 40 transfer RNA genes. The gene… Expand

Identification and Phylogenetic Analysis of the Complete Chloroplast Genomes of Three Ephedra Herbs Containing Ephedrine
This research provided valuable information for the identification and phylogenetic analysis of gymnosperms and drug safety of Ephedra, which had a close phylogenetic relationship with Gnetum species and Welwitschia mirabilis. Expand
India is the home of numerous medicinally significant plants. These plants are used by people from over centuries. Among these plants, we have Gnetum ula (G. ula) which is found in India (WesternExpand
Molecular digitization of a botanical garden: high-depth whole-genome sequencing of 689 vascular plant species from the Ruili Botanical Garden
The large dataset of vascular plant genomes generated in this study, which includes both high-depth whole-genome sequencing data and associated voucher specimens, is valuable for plant genome research and other applications and provides insight into the feasibility and technical requirements for “planetary-scale” projects such as the 10,000 Plant Genomes Project and the Earth BioGenome Project.

Evolutionary studies of the Gnetales
The Gnetales consist of three distinct genera, Ephedra, Gnetum and Welwitschia with considerable divergence among them regarding morphological, ecological and molecular characters. A longstanding dExpand


Evolution of reduced and compact chloroplast genomes (cpDNAs) in gnetophytes: selection toward a lower-cost strategy.
The reduced gnetophyte cpDNAs clearly resulted from selection for economy by deletions of genes and non-coding sequences, which then led to the compactness and the accelerated substitution rates, and the smallest C-values in g netophyte nuclear DNAs further suggest a critical need for an economic strategy.

Seed plant phylogeny and the origin of angiosperms: An experimental cladistic approach
The results raise the possibility that many features considered key adaptations in the origin and rise of angiosperms were actually inherited from their gymnospermous precursors, and the morphological diversity of Mesozoic anthophytes could provide critical tests of relationships. Expand
The evolution of double fertilization and endosperm: an ”historical” perspective
Developmental analyses of Ephedra and Gnetum indicate that these nonflowering seed plants undergo a regular process of double fertilization that yields two diploid zygotes, demonstrating congruence with the hypothesis thatdouble fertilization processes in Gnetales and angiosperms were inherited from a common ancestor of the two lineages.

MEGA6: Molecular Evolutionary Genetics Analysis version 6.0.
An advanced version of the Molecular Evolutionary Genetics Analysis software, which currently contains facilities for building sequence alignments, inferring phylogenetic histories, and conducting molecular evolutionary analysis, is released, which enables the inference of timetrees, as it implements the RelTime method for estimating divergence times for all branching points in a phylogeny.
