The expression of liver–gonadal axis genes reveals the long–term effects of exogenous estradiol on gonad development and liver function in GIFT tilapia

open access: yesReproduction and Breeding
The aim of this study was to investigate the effects of exogenous estradiol on the expression of the liver–gonadal axis gene in GIFT tilapia. Larval fish (5 dph) were fed a diet with 100 mg kg−1 17α–ethynylestradiol (EE2) for 30 days and then transferred

Unveiling the phylogenetic position of the type species of the syndinean genus Amoebophrya and broad divergence of the A. ceratii complex. [PDF]

open access: yesJ Phycol
Abstract The syndinean genus Amoebophrya comprises endoparasitic dinoflagellates that infect various marine protists. Since the description of the type species, A. sticholonchae, a parasite of the radiolarian Sticholonche zanclea, an additional six Amoebophrya species have been formally described.

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]

open access: yes, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

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

Experimental validation of genomic selection in Sugarcane : P0197 [PDF]

open access: yes, 2013
Sugarcane cultivars (Saccharum spp.) are interspecific hybrids characterized by highly heterozygous and polyploid genome. Genomic selection (GS) approach is believed to be well suited for complex traits by including all markers in prediction models.

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 ...

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

open access: yesNew Phytologist, EarlyView.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Molecular and morphological phylogenetics of the digitate-tubered clade within subtribe Orchidinae s.s. (Orchidaceae: Orchideae) [PDF]

open access: yes, 2018
The digitate-tubered clade (Dactylorhiza s.l. plus Gymnadenia s.l.) within subtribe Orchidinae is an important element of the North-temperate orchid flora and has become a model system for studying the genetic and epigenetic consequences of organism-wide

Somatic genome‐doubling is the most parsimonious route to allopolyploidy

open access: yesNew Phytologist, EarlyView.
Summary The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome‐doubling and re‐writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable.

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.
