Do methods for overcoming dormancy affect the physiological quality of okra seeds?

Pesquisa Agropecuária Tropical, 2023
One of the main obstacles in the okra production is the physical dormancy imposed by the tegument of the seeds. Although several methods for overcoming tegumentary dormancy have been proposed, little is known about their effect on the physiological ...

Delayed Germination of Seeds: A Look at the Effects of Adult Longevity, the Timing of Reproduction, and Population Age/Stage Structure [PDF]

, 1994
The effects of adult longevity, the timing of reproduction, and population age/stage structure on the evolution of seed dormancy are explored in both constant and variable environment models. In the constant environment models complete germination is the

How fall dormancy benefits alfalfa winter-survival? Physiologic and transcriptomic analyses of dormancy process [PDF]

BMC Plant Biology, 2019
Fall dormancy and freezing tolerance characterized as two important phenotypic traits, have great effects on productivity and persistence of alfalfa (Medicago sativa L.). Despite the fact that one of the most limiting traits for alfalfa freezing tolerance in winter is fall dormancy, the interplay between fall dormancy and cold acclimation processes of ...

Principles of seed banks: complexity emerging from dormancy [PDF]

Nat Commun 12, 4807 (2021), 2020
Across the tree of life, populations have evolved the capacity to contend with suboptimal conditions by engaging in dormancy, whereby individuals enter a reversible state of reduced metabolic activity. The resulting seed banks are complex, storing information and imparting memory that gives rise to multi-scale structures and networks spanning ...

Evolutionary trade-offs in dormancy phenology

eLife
Seasonal animal dormancy is widely interpreted as a physiological response for surviving energetic challenges during the harshest times of the year (the physiological constraint hypothesis).

Poplar woody root proteome during the transition dormancy-active growth [PDF]

, 2013
Woody plants living in temperate climates finely regulate their growth and development in relation to seasonal changes; their transition from vegetative to dormancy phase represents an adaptation to their environment. Events occurring in the shoot during

Physiological Studies on Dormancy in Cape Tulip [PDF]

Australian Journal of Biological Sciences, 1969
A high proportion of cormils of the two leaved species of the weed, Cape tulip, showed long-term dormancy, and e.xperiments showed that this dormancy is not due to a high level of endogenous growth inhibitors but is due to physical factors associated with the presence of intact cormil coats.

FoxO1 signaling in B cell malignancies and its therapeutic targeting

FEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Cool–Warm Temperature Stratification and Simulated Bird Digestion Optimize Removal of Dormancy in Rosa rugosa Seeds

Frontiers in Plant Science, 2022
Rosa rugosa Thunb. has been explored multi-function in medicinal, edible, cosmetic, ornamental and ecological etc. However, R. rugosa natural populations have recently declined substantially in China, besides of global climate change, this species also ...

Co-Contagion Diffusion on Multilayer Networks [PDF]

Applied Network Science. 4.78 (2019), 2019
This study examines the interface of three elements during co-contagion diffusion: the \textbf{synergy} between contagions, the \textbf{dormancy} rate of each individual contagion, and the \textbf{multiplex network topology}. Dormancy is defined as a weaker form of "immunity," where dormant nodes no longer actively participate in diffusion, but are ...
