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

Chromatin loops gather targets of upstream regulators together for efficient gene transcription regulation during vernalization in wheat

Genome Biology
Background Plants respond to environmental stimuli by altering gene transcription that is highly related with chromatin status, including histone modification, chromatin accessibility, and three-dimensional chromatin interaction.

The MED30 subunit of mediator complex is essential for early plant development and promotes flowering in arabidopsis thaliana [PDF]

, 2019
Mediator is a large multiprotein complex that is required for the transcription of most, if not all, genes transcribed by RNA Polymerase II. A core set of subunits is essential to assemble a functional Mediator in vitro and, therefore, the corresponding ...

Pharmacokinetics of Topical Administration of Altrenogest in Mares and Implications for Human Health

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Altrenogest is a synthetic progestogen widely used in equine reproductive management. Adverse effects to altrenogest have been reported in people with cutaneous exposure reported as the highest exposure pathway. Despite these reports, there has been no quantitative research to determine the capacity for altrenogest to be absorbed through skin.

Influence of seed vernalization on production, growth and development of lisianthus

Semina: Ciências Agrárias, 2018
Flowering induction and control is a limiting factor when commercially producing cut flowers of lisianthus and seed exposure to low temperatures, a physiological event called vernalization, induces the differentiation of vegetative buds to reproductive ...

VERNALIZATION2 alters early tiller development in a facultative spring hexaploid bread wheat

New Phytologist, EarlyView.
Summary An extended period of cold exposure enables the process of vernalization in winter cereals and is important for the synchronised timing of the floral transition. The cereal‐specific floral repressor VERNALIZATION2 (VRN2) has an integral role in vernalization, yet this locus remains poorly characterised in facultative spring hexaploid wheat ...

Vernalization requirement and the chromosomal VRN1-region can affect freezing tolerance and expression of cold-regulated genes in Festuca pratensis

Frontiers in Plant Science, 2016
Plants adapted to cold winters go through annual cycles of gain followed by loss of freezing tolerance (cold acclimation and deacclimation). Warm spells during winter and early spring can cause deacclimation, and if temperatures drop, freezing damage may

Vernalization-repression of Arabidopsis FLC requires promoter sequences but not antisense transcripts. [PDF]

PLoS ONE, 2011
The repression of Arabidopsis FLC expression by vernalization (extended cold) has become a model for understanding polycomb-associated epigenetic regulation in plants.

Effect of Planting Date, Clipping Height, and Cultivar on Forage and Grain Yield of Winter Wheat in Argentinean Pampas [PDF]

, 2006
In Argentinean Pampas, new wheat (Triticum aestivum L.) cultivars are routinely introduced to farmers for dual-purpose production. The objective of this study was to evaluate the effect of planting date, clipping height on forage, and grain yield for ...

Vernalization regulatory network identifies potential novel functions for genes in the HvVRN2 locus

New Phytologist, EarlyView.
Summary Flowering is controlled by environmental and genetic factors. Vernalization requirement in barley (Hordeum vulgare L.) is determined by the allele in HvVRN1 and the presence of locus HvVRN2, which consists of two zinc‐finger and CONSTANS‐like domains (ZCCT) genes: HvVRN2a and HvVRN2b.
