Effect of Seed Dormancy Breaking Treatments on Germination and α-amylase Enzyme Activity in Seeds of Three Ecotypes of Astragalus (Astragalus cyclophyllu)

open access: yesپژوهش‌های بذر ایران, 2020
DOR: 98.1000/2383-1251.1398. 6.15.12.2.1575.41 Extended Abstract  Introduction: Seed dormancy, as a technique to avoid environmental stress, is important in preserving plant species and could be of various types including physiological, physical ...

Pengaruh Pematahan Dormansi Secara Fisik Dan Kimia Terhadap Kemampuan Berkecambah Benih Mucuna (Mucuna Bracteata D.c) [PDF]

open access: yes, 2014
Generative propagation of mucuna produces low germination percentage and requires long time togerminate due to seed dormancy which is caused by the seed coat that is impermiable to oxygenand/or water.

TGF-β2 dictates disseminated tumour cell fate in target organs through TGF-β-RIII and p38α/β signalling [PDF]

open access: yes, 2013
In patients, non-proliferative disseminated tumour cells (DTCs) can persist in the bone marrow (BM) while other organs (such as lung) present growing metastasis.

Cell Cycle Control of Nuclear Metabolism Couples Phosphatidylinositol Signaling to Histone Methylation

open access: yesAdvanced Science, EarlyView.
Nuclear metabolism oscillates during cell cycle progression. Quantitative chromatome proteomics and imaging reveal phase‐specific dynamics of PIP5K1A and nuclear PIP2, linking phosphatidylinositol metabolism to histone methylation. This work identifies nuclear lipid metabolism as a previously unrecognized regulatory axis coordinating chromatin ...

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Genotypic variation of dormancy in wheat (Triticum aestivum L.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science, Department of Plant Science, Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 1996
Embryo dormancy and α - amylase dormancy are desirable in wheat to minimise pre-harvest sprouting damage. The current work focuses on the embryo and graincoat colour.

DCAF13 Safeguards Hematopoietic Stem Cells via RRS1‐Regulated Ribosome Biogenesis

open access: yesAdvanced Science, EarlyView.
This study establishes DCAF13 as an essential regulator for hematopoietic stem cell (HSC) function. Its deletion in mice causes lethal pancytopenia and HSC depletion. Mechanistically, DCAF13 interacts with RRS1 and mediates its non‐degradative K27‐linked ubiquitination, thereby stabilizing RRS1 to maintain ribosome biogenesis and protein translation ...

Weedy adaptation in Setaria spp.: IX. Effects of salinity, temperature, light and seed dormancy on Setaria faberi seed germination [PDF]

open access: yes, 2014
Life in salty habitats is a function of tolerance to those chemicals at all critical phases of a plant's life history. The ability to withstand salt as an established plant may require different mechanisms and plant traits than those needed to germinate ...

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

open access: yesAdvanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Differential incidence of the lemma on seed germination among different Paspalum dilatatum genotypes

open access: yesJournal of Seed Science
: Paspalum dilatatum Poir. is a promising perennial summer grass forage for temperate regions, but among other factors, slow stand establishment has hindered its adoption. One of the reasons may be seed dormancy.
