Fire Seasonality, Seasonal Temperature Cues, Dormancy Cycling, and Moisture Availability Mediate Post-fire Germination of Species With Physiological Dormancy [PDF]
Frontiers in Plant Science, 2021 Fire seasonality (the time of year of fire occurrence) has important implications for a wide range of demographic processes in plants, including seedling recruitment.

Trait analysis reveals DOG1 determines initial depth of seed dormancy, but not changes during dormancy cycling that result in seedling emergence timing. [PDF]
New Phytol, 2020 Summary Seedling emergence timing is crucial in competitive plant communities and so contributes to species fitness. To understand the mechanistic basis of variation in seedling emergence timing, we exploited the contrasting behaviour of two Arabidopsis thaliana ecotypes: Cape Verde Islands (Cvi) and Burren (Bur‐0).

Unravelling the paradox in physically dormant species: elucidating the onset of dormancy after dispersal and dormancy-cycling. [PDF]
Ann Bot, 2022 Abstract Background For species that produce seeds with a water-impermeable coat, i.e. physical dormancy (PY), it has been widely recognized that (1) seeds shed at a permeable state cannot become impermeable after dispersal; and (2) dormancy-cycling, i.e. a permeable ↔ impermeable transition, does not

Seed dormancy cycling and the regulation of dormancy mechanisms to time germination in variable field environments [PDF]
Journal of Experimental Botany, 2017 Many molecular mechanisms that regulate dormancy have been identified individually in controlled laboratory studies. However, little is known about how the seed employs this complex suite of mechanisms during dormancy cycling in the variable environment of the soil seed bank.

Regulation of cell cycle regulators by environmental signals during growth-dormancy cycle of trees [PDF]
Plant Signaling & Behavior, 2009 Climate change such as changing temperature and increasing concentrations of atmospheric CO(2), are likely to drive significant modifications in forests. While many studies have demonstrated the responses and adoptions of tree to fluctuations in climatic and environmental conditions, the impact of environmental signals on trees is complex and poorly ...

Photoperiodic Regulation of Growth-Dormancy Cycling through Induction of Multiple Bud–Shoot Barriers Preventing Water Transport into the Winter Buds of Norway Spruce [PDF]
Frontiers in Plant Science, 2017 Whereas long days (LDs) sustain shoot elongation, short days (SDs) induce growth cessation and formation of dormant buds in young individuals of a wide range of temperate and boreal tree species.

Dormancy Cycling in Populus: The Symplasmic Connection [PDF]
The Plant Cell, 2011 Plants in temperate climates have a variety of strategies to survive the cold and dessicating conditions of winter. Annuals grow during the warm months and then set seed that will survive the winter and produce a new generation the following year.

Dormancy cycling and persistence of seeds in soil of a cold desert halophyte shrub. [PDF]
Ann Bot, 2014 Formation of seed banks and dormancy cycling are well known in annual species, but not in woody species. In this study it was hypothesized that the long-lived halophytic cold desert shrub Kalidium gracile has a seed bank and dormancy cycling, which help restrict germination to a favourable time for seedling survival.Fresh seeds were buried in November ...

Hormonal Orchestration of Bud Dormancy Cycle in Deciduous Woody Perennials [PDF]
Frontiers in Plant Science, 2019 Woody perennials enter seasonal dormancy to avoid unfavorable environmental conditions. Plant hormones are the critical mediators regulating this complex process, which is subject to the influence of many internal and external factors. Over the last two decades, our knowledge of hormone-mediated dormancy has increased considerably, primarily due to ...

Gene expression profiles of Arabidopsis Cvi seeds during dormancy cycling indicate a common underlying dormancy control mechanism [PDF]
The Plant Journal, 2006 SummaryPhysiologically dormant seeds, like those of Arabidopsis, will cycle through dormant states as seasons change until the environment is favourable for seedling establishment. This phenomenon is widespread in the plant kingdom, but has not been studied at the molecular level.
