Dormancy in reproductive vegetative buds in creeping perennials dominating the agricultural weed flora in Scandinavia [PDF]

, 2013
Dormancy, which is the inability to initiate normal growth under otherwise favourable conditions, is an adaptation to escape sprouting prior to seasonal cold temperatures and/or drought in areas where winters are harsh or summers dry.

Cytological and transcript analyses reveal fat and lazy persister-like bacilli in tuberculous sputum [PDF]

, 2008
As nonreplicating tubercle bacilli are tolerant to the cidal action of antibiotics and resistant to multiple stresses, identification of this persister-like population of tubercle bacilli in sputum presents exciting and tractable new opportunities to ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

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

پژوهش‌های 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 ...

Seed dormancy in ornamental plants: A review

The Indian Journal of Agricultural Sciences, 2016
Seed is the first input used in transfer of genetic traits in ornamental plants production. Seed dormancy is a physiological phenomenon in plants, which is caused by external or internal factors, and prevents seed germination, even in optimal conditions.

Notes on the germination of the endangered species Sclerolaena napiformis (Chenopodiaceae) [PDF]

, 2013
Sclerolaena napiformis is found on fertile plains in northern Victoria and southern New South Wales and is endangered Australia-wide. Introductory work on its germination shows that seeds cannot germinate until the woody fruit has broken down.

Temperature, light and nitrate sensing coordinate Arabidopsis seed dormancy cycling resulting in winter and summer annual phenotypes [PDF]

, 2013
Seeds use environmental cues to sense the seasons and their surroundings to initiate the plants life cycle. Dormancy cycling underlying this process is extensively described, but the molecular mechanism is largely unknown.

Overcoming physiological dormancy in common buckwheat (Fagopyrum esculentum Moench)

Genetic Resources and Crop Evolution, 2023
Abstract The viability status of every accession stored in a seed bank is essential for effective germplasm conservation, and it is often assessed through germination tests. However, the presence of dormancy can impede this process. The dormancy release protocols for buckwheat seeds, which exhibit physiological dormancy, are not available. This

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
