A guide to phylogenetic metrics for conservation, community ecology and macroecology

open access: yesBiological Reviews of The Cambridge Philosophical Society, 2016
The use of phylogenies in ecology is increasingly common and has broadened our understanding of biological diversity. Ecological sub‐disciplines, particularly conservation, community ecology and macroecology, all recognize the value of evolutionary ...

Modern and Ancient Genomes Reveal Neolithic Paternal Expansions of Millet and Rice Farmers and Demic Diffusion from China into Mainland Southeast Asia

open access: yesAdvanced Science, EarlyView.
This study clarifies the genetic patterns of paternal lineages across East Asia and Mainland Southeast Asia. Han populations are relatively homogeneous, whereas southern ethnolinguistic minorities display regional structures. Shared Y‐chromosome lineages indicate Neolithic expansions and extensive north‐south gene flow, supporting demic diffusion ...

The complete chloroplast genome sequence of Hypecoum erectum L. (Papaveraceae)

open access: yesMitochondrial DNA. Part B. Resources
Hypecoum erectum L., a widespread species in northern Eurasia, is a valuable medicinal plant, but its chloroplast genome has not previously been reported. We determined its complete chloroplast genome using a high-throughput sequencing technique.

TOGR3, a Proteasome β4 Subunit, Orchestrates Sugar Homeostasis to Trade Off Growth and Thermotolerance in Rice

open access: yesAdvanced Science, EarlyView.
This study identifies a novel thermoregulatory mechanism in rice: TOGR3 partners with 26S proteasome subunits, including TT1, to drive thermoresponsive ubiquitin–proteasome activity, maintaining sugar homeostasis in stomatal regulation to balance growth and stress resistance.

The Iranian Hyalomma (Acari: Ixodidae) with molecular evidences to understand taxonomic status of species complexes

open access: yesPersian Journal of Acarology, 2019
The identification of Hyalomma is a challenging issue in the systematics of ixodid ticks. Here, we examined 960 adult males of Hyalomma tick from 10 provinces of Iran using morphological and molecular methods.

Whole genome analysis of diverse Chlamydia trachomatis strains identifies phylogenetic relationships masked by current clinical typing

open access: yesNature Genetics, 2012
Chlamydia trachomatis is responsible for both trachoma and sexually transmitted infections, causing substantial morbidity and economic cost globally. Despite this, our knowledge of its population and evolutionary genetics is limited.
