The complete chloroplast genome sequence of Calanthe delavayi (Orchidaceae), an endemic to China

Mitochondrial DNA. Part B. Resources, 2019
Calanthe delavayi, an endemic terrestrial orchid distributed in southwestern China. In this study, the complete chloroplast genome (cpDNA) sequence of C. delavayi was determined from Illumina pair-end sequencing data. With a total length of 150,181 bp in

Entanglement Invariants and Phylogenetic Branching [PDF]

arXiv, 2004
It is possible to consider stochastic models of sequence evolution in phylogenetics in the context of a dynamical tensor description inspired from physics. Approaching the problem in this framework allows for the well developed methods of mathematical physics to be exploited in the biological arena.

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

American Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Sequence and phylogenetic analysis of the complete mitochondrial genome for Hepu mitten crab (Eriocheir hepuensis) from Nanjiujiang River basin

Mitochondrial DNA. Part B. Resources, 2019
Taxonomic classification of Eriocheir hepuensis was ambiguous, and it has long been controversial. In this study, the whole mitochondrial genome of E. hepuensis was determined to be 16,397 bp, including 13 protein-coding genes, 22 transfer RNA genes, 2 ...

Decoding the Chemical Language of Ribosomally Synthesized and Post‐Translationally Modified Peptides from the Untapped Archaea Domain

Angewandte Chemie, EarlyView.
Secondary metabolites (SMs) are essential across all life domains, yet those originating from the Archaea domain remain poorly understood. Here, the systematic genome mining and the pioneering heterologous expression of archaeal SMs have revealed the chemical landscape of archaeal lanthipeptides, showing both canonical and non‐canonical forms.

Osmoxylon‐like fossils from early Eocene South America: West Gondwana–Malesia connections in Araliaceae

American Journal of Botany, EarlyView.
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Complete chloroplast genome sequence of Mirabilis himalaica (Nyctaginaceae)

Mitochondrial DNA. Part B. Resources, 2019
Mirabilis himalaica (Nyctaginaceae) is endemic to the Himalayas where it is used in traditional Tibetan folk medicine. In this study, we first presented the complete chloroplast genome of M. himalaica. Complete genome size of M. himalaica ranged from 154,

Phylogenetic Networks Do not Need to Be Complex: Using Fewer Reticulations to Represent Conflicting Clusters [PDF]

arXiv, 2009
Phylogenetic trees are widely used to display estimates of how groups of species evolved. Each phylogenetic tree can be seen as a collection of clusters, subgroups of the species that evolved from a common ancestor. When phylogenetic trees are obtained for several data sets (e.g.
