Transport engineering as a strategy to realize rapeseed's potential as a protein‐rich food

Pest Management Science, EarlyView.
The heavily pesticide‐dependent rapeseed is an under‐utilized protein source for food owing to anti‐nutritional glucosinolates. Transport engineering technology may reduce glucosinolates in seeds while increasing defense in vegetative parts. Abstract Rapeseed is the world's second‐largest oilseed crop, and the low‐value press cake that remains after ...

The frequency and importance of polyploidy in tropical rainforest tree radiations

New Phytologist, EarlyView.
Summary The presence of two or more copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. The Amazonian tree flora is the most species‐rich on Earth and largely arose as a result of rapid evolutionary radiations. While polyploidy is an important catalyst

Bulbil formation in stress: Crucial role of triploid fitness in mixed ploidy dynamics in Costus speciosus

Plant Species Biology, EarlyView.
Upon prolonged waterlogging, a Costus speciosus plant developed bulbils at stem node. Karyotype analysis, nucleolar staining, and anatomical study revealed its triploid status and developmental aspects. Prevalence of tetraploid, abundance, and unique reproductive fecundity of the triploid, indicates its determinant role in coexistence of the multiple ...

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

Reproduction 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

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

Insect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

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

, 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 ...

Chromosomal Diversity as a Predictor of Lineage Diversification in Ants Across Phylogenetic and Geographic Gradients

Journal of Biogeography, EarlyView.
ABSTRACT Aim To investigate macroevolutionary and biogeographic patterns of chromosome number variation in ants (Formicidae), and to test whether chromosomal diversity is taxonomically structured, associated with species richness, varies with latitude, and accumulates over evolutionary time. Location Global.

Revised phylogeny of the Inula complex group (Asteraceae: Inuleae) with a recircumscription of Carpesium and establishment of a new genus Cladocarpesium

Journal of Systematics and Evolution, EarlyView.
Cladocarpesium T. Deng & Qun Liu, gen. nov. (Separated from Carpesium) is established with Cladocarpesium abrotanoides (L.) T. Deng & Qun Liu designated as the type species. The new genus is morphologically distinct from Carpesium s.str. by its sympodial growth form (typically producing three branches), sessile capitula, and three‐seriate phyllaries ...

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
