Biophysical boundaries for dormancy release in sunflower achenes

Journal of Experimental Botany
Abstract Reactions leading to dormancy release (DR) in ‘dry’, orthodox seeds are still poorly understood, as well as their dependence on moisture content (MC) and temperature. In this study, sunflower achenes were used to explore the effects of MC combined with a wide range of storage temperatures (ST°) on DR dynamics, tested at 10 °C

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Impacts of climate change on the transcriptional dynamics and timing of bud dormancy release in Yoshino‐cherry tree

Plants, People, Planet
Societal Impact Statement The iconic Yoshino cherry tree in Japan is experiencing shifts in its blossom timing due to climate warming. To develop a genetically informed predictive model for bud dormancy release, we examined seasonal gene expression in ...

Plant hormonal changes and differential expression profiling reveal seed dormancy removal process in double dormant plant-herbaceous peony.

PLoS ONE, 2020
Herbaceous peony (Paeonia lactiflora Pall.) is a popular ornamental and medicinal plant. Taking approximately six to seven months, the seeds germination under natural conditions experiences dual dormancies, which seriously affects horticultural ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The release of dormancy, a wake-up call for seeds to germinate

Current Opinion in Plant Biology, 2017
Seed dormancy determines the timing of germination, thereby contributing to successful seedling establishment and plant fitness. The induction and release of dormancy are controlled by various regulators like plant hormones and dormancy proteins. The relative strengths of these regulators are influenced by environmental factors during seed maturation ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Gamma-aminobutyric acid (GABA) releases seed dormancy by orchestrating abscisic acid and gibberellin metabolism and signaling

BMC Plant Biology
Background Seed dormancy release, regulated by abscisic acid (ABA) and gibberellin (GA), is essential for plant development and yield. Gamma-aminobutyric acid (GABA) is known to mediate plant stress responses; however, its role in seed dormancy release ...

Transcriptomic Analysis Reveals the Positive Role of Abscisic Acid in Endodormancy Maintenance of Leaf Buds of Magnolia wufengensis

Frontiers in Plant Science, 2021
Magnolia wufengensis (Magnoliaceae) is a deciduous landscape species, known for its ornamental value with uniquely shaped and coloured tepals. The species has been introduced to many cities in south China, but low temperatures limit the expansion of this

CYTOLOGICAL STUDIES IN DORMANCY III. CHANGES DURING LOW‐TEMPERATURE DORMANCY RELEASE [PDF]

New Phytologist, 1972
SummaryThe cytological changes occurring in dormant embryo radicle meristem cells of Fraxinus excelsior during the period of chilling before germination are described. The only events observed to be dependent on low temperature occurred in the nucleolus, which increased in volume and complexity of structure.
