WRKY Gene Family Drives Dormancy Release in Onion Bulbs [PDF]
Cells, 2022 Onion (Allium cepa L.) is an important bulb crop grown worldwide. Dormancy in bulbous plants is an important physiological state mainly regulated by a complex gene network that determines a stop of vegetative growth during unfavorable seasons.

Wake up: the regulation of dormancy release and bud break in perennial plants [PDF]
Frontiers in Plant ScienceIn order to survive harsh winter conditions, perennial trees in the temperate and frigid regions enter a dormant state and cease growth in late summer after vigorous growth in spring and summer.

Variable temperature processing by plasmodesmata regulates robust bud dormancy release [PDF]
Nature CommunicationsDormancy is a key mechanism in perennial plants in boreal and temperate regions, protecting buds from winter damage by repressing precocious bud break before spring onset.

A tree peony RING-H2 finger protein, PsATL33, plays an essential role in cold-induced bud dormancy release by regulating gibberellin content [PDF]
Frontiers in Plant ScienceBud dormancy is crucial for woody perennial plants to resist low-temperature stress in winter. However, the molecular regulatory mechanisms underlying bud dormancy release are largely unclear.

Bulb Dormancy In Vitro—Fritillaria meleagris: Initiation, Release and Physiological Parameters [PDF]
Plants, 2021 In ornamental geophytes, conventional vegetative propagation is not economically feasible due to very slow development and ineffective methods. It can take several years until a new plant is formed and commercial profitability is achieved.

Seed dormancy revisited: Dormancy‐release pathways and environmental interactions
Functional Ecology, 2023 Abstract Many internal (inherent) and environmental (imposed) factors control seed dormancy and germination that we divide into three basic dormancy‐release pathways: Maternal structures and embryo physiology control inherent dormancy that is broken by various types of scarification and physiological changes, followed by imposed‐dormancy release when

Fire‐released seed dormancy ‐ a global synthesis
Biological Reviews, 2022 ABSTRACTSeed dormancy varies greatly between species, clades, communities, and regions. We propose that fireprone ecosystems create ideal conditions for the selection of seed dormancy as fire provides a mechanism for dormancy release and postfire conditions are optimal for germination. Thus, fire‐released seed dormancy should vary in type and abundance
