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

Journal 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

Analysis of testicular germ cell apoptosis in Cobitis loaches (Cobitidae, Teleostei) from diploid-tetraploid populations

Frontiers in Marine Science, 2015
Taxa of the genus Cobitis are distributed in Europe mainly in populations composed of individuals at different ploidy level. The species occur in Poland include the spined loach C. taenia and the Danubian loach C.

Exploiting next-generation sequencing to solve the haplotyping puzzle in polyploids: a simulation study

Briefings Bioinform., 2017
Haplotypes are the units of inheritance in an organism, and many genetic analyses depend on their precise determination. Methods for haplotyping single individuals use the phasing information available in next-generation sequencing reads, by matching ...

Evolutionary history of Hypericum perforatum L. [PDF]

, 2011
The genus Hypericum is a highly diverse group of about 500 species. Among the Eurasian taxa, Hypericum perforatum L. and H. maculatum Crantz are representative examples with a largely overlapping distribution area in Central Europe.

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

New 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 ...

Origin and evolution of the octoploid strawberry genome. [PDF]

, 2019
Cultivated strawberry emerged from the hybridization of two wild octoploid species, both descendants from the merger of four diploid progenitor species into a single nucleus more than 1 million years ago.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Ecological and evolutionary implications of hybridization, polyploidy and apomixis in angiosperms

Botan‪ical Sciences
Hybridization, polyploidy, and apomixis are related to the diversification of angiosperms, generating complex taxonomic relationships between species. Despite the differences in the frequencies of these phenomena, apomixis, the asexual seed production ...

Reproductive pathways in Hieracium s.s. (Asteraceae): strict sexuality in diploids and apomixis in polyploids

Annals of Botany, 2018
Background and Aims Apomixis or asexual seed reproduction is a key evolutionary mechanism in certain angiosperms providing them with reproductive assurance and isolation.
