Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Molecular cytogenetic differentiation of paralogs of Hox paralogs in duplicated and re-diploidized genome of the North American paddlefish (Polyodon spathula). [PDF]

open access: yes, 2017
BackgroundAcipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species of sturgeons and paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence of ...

Whole genome sequencing of historical specimens from the world's largest fungal collection yields high‐quality assemblies

open access: yesNew Phytologist, EarlyView.
Summary High‐throughput molecular studies of museum specimens (museomics) have great potential in biodiversity research, but fungal historical collections have scarcely been examined, leading to no comprehensive methodological assessments. Here we present a whole genome sequencing (WGS) project conducted at the Fungarium of the Royal Botanic Gardens ...

De novo construction of polyploid linkage maps using discrete graphical models

open access: yes, 2018
Linkage maps are used to identify the location of genes responsible for traits and diseases. New sequencing techniques have created opportunities to substantially increase the density of genetic markers.

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

open access: yes, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

The annotated blueprint: integrated functional genomic resources for a model tetraploid wheat Triticum turgidum cv Kronos

open access: yesNew Phytologist, EarlyView.
Summary Triticum turgidum cv Kronos is a tetraploid wheat cultivar that underpins one of the most widely used community platforms for functional genomics. Over the past decade, researchers have generated c. 3000 exome‐capture (EC) and promoter‐capture (PC) datasets linked to mutagenized seed stocks, along with extensive transcriptomic and phenotypic ...

Identification of sex-determination regions and development of male-specific markers for topmouth culter (Culter alburnus)

open access: yesAquaculture Reports
The topmouth culter (Culter alburnus), a carnivorous freshwater species in the family Cyprinidae (order Cypriniformes), holds high economic value and displays marked sexual dimorphism in growth, where females exhibit accelerated growth relative to males.

Polyploid races, genetic structure and morphological features of the earthworm Octodrіlus transpadanus (Rosa, 1884) (Oligohaeta: Lumbricidae) in the Ukraine [PDF]

open access: yes, 2009
Kariological investigation of the earthworm Octodrilus transpada-nus (Rosa, 1884) in the Ukraine showed that this species is represented by at least three races of different ploidy with the basic chromosome number n=15. Strict geographic heterogeneity

Recombination suppression in plant adaptation and speciation

open access: yesNew Phytologist, EarlyView.
Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Experimental Control and Characterization of Autophagy in Drosophila [PDF]

open access: yes, 2008
Insects such as the fruit fly Drosophila melanogaster, which fundamentally reorganize their body plan during metamorphosis, make extensive use of autophagy for their normal development and physiology.
