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.

Unravelling the paradox in physically dormant species: elucidating the onset of dormancy after dispersal and dormancy-cycling. [PDF]
Ann Bot, 2022 BACKGROUND For species that produce seeds with a water-impermeable coat, i.e. physical dormancy (PY), it has been widely recognised in the available literature that (i) seeds shed at a permeable state cannot become impermeable after dispersal; and (ii ...

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 ...

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: translation-related transcripts are the main difference between dormant and non-dormant seeds in the field. [PDF]
Plant J, 2020 Summary Primary seed dormancy is a mechanism that orchestrates the timing of seed germination in order to prevent out‐of‐season germination. Secondary dormancy can be induced in imbibed seeds when they encounter prolonged unfavourable conditions ...

A laboratory simulation of Arabidopsis seed dormancy cycling provides new insight into its regulation by clock genes and the dormancy-related genes DOG1, MFT, CIPK23 and PHYA. [PDF]
Plant Cell Environ, 2017 Environmental signals drive seed dormancy cycling in the soil to synchronize germination with the optimal time of year, a process essential for species' fitness and survival.

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.

Tumor Dormancy and Slow-Cycling Cancer Cells
Advances in Experimental Medicine and Biology, 2019 Cancer cell heterogeneity is a universal feature of human tumors and represents a significant barrier to the efficacy and duration of anticancer therapies, especially targeted therapeutics. Among the heterogeneous cancer cell populations is a subpopulation of relatively quiescent cancer cells, which are in the G0/G1 cell-cycle phase and refractory to ...

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.

Seed dormancy cycling in Arabidopsis: chromatin remodelling and regulation of DOG1 in response to seasonal environmental signals. [PDF]
Plant J, 2015 The involvement of chromatin remodelling in dormancy cycling in the soil seed bank (SSB) is poorly understood. Natural variation between the winter and summer annual Arabidopsis ecotypes Cvi and Bur was exploited to investigate the expression of genes ...
