Nature Communications, 2023 Mother plants play an important role in the control of dormancy and dispersal characters of their progeny. In Arabidopsis seed dormancy is imposed by the embryo-surrounding tissues of the endosperm and seed coat.

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

Setaria faberi Seed Heteroblasty Blueprints Seedling Recruitment: II. Seed Behavior in the Soil [PDF]
, 2012 The fate of heteroblastic Setaria faberi seed entering the soil post-abscission is elucidated. Introduction of four populations of S. faberi seeds with heterogeneous dormancy capacities into the soil of a no-till Glycine max field resulted in the ...

Environmental Regulation of Weed Seed Dormancy and Germination
Seeds, 2023 Many weeds produce dormant seeds that are unable to complete germination under favourable conditions. There are two types of seed dormancy: primary dormancy (innate dormancy), in which seeds are in a dormant state upon release from the parent plant, and ...

Understanding lolium rigidum seeds: The key to managing a problem weed? [PDF]
, 2012 The 40 million hectare southern Australian winter cropping region suffers from widespread infestation by Lolium rigidum (commonly known as annual or rigid ryegrass), a Mediterranean species initially introduced as a pasture plant.

Polymorphic homoeolog of key gene of RdDM pathway, ARGONAUTE4_9 class is associated with pre-harvest sprouting in wheat (Triticum aestivum L.). [PDF]
PLoS ONE, 2013 Resistance to pre-harvest sprouting (PHS) is an important objective for the genetic improvement of many cereal crops, including wheat. Resistance, or susceptibility, to PHS is mainly influenced by seed dormancy, a complex trait.

Anthropogenic seed dispersal: rethinking the origins of plant domestication
, 2020 It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as

Tanned or burned: the role of fire in shaping physical seed dormancy. [PDF]
PLoS ONE, 2012 Plant species with physical seed dormancy are common in mediterranean fire-prone ecosystems. Because fire breaks seed dormancy and enhances the recruitment of many species, this trait might be considered adaptive in fire-prone environments.

Seed dormancy and germination [PDF]
Current Biology, 2017 Reproduction is a critical time in plant life history. Therefore, genes affecting seed dormancy and germination are among those under strongest selection in natural plant populations. Germination terminates seed dispersal and thus influences the location and timing of plant growth.

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]
, 2017 Environmental signals drive seed dormancy cycling in the soil to synchronise germination with the optimal time of year; a process essential for species fitness and survival.
