Multiomics strategies for decoding seed dormancy breakdown in Paris polyphylla

open access: yesBMC Plant Biology, 2023
Background The disruption of seed dormancy is a complicated process and is controlled by various factors. Among these factors, membrane lipids and plant hormones are two of the most important ones.

Jasmonic acid-dependent regulation of seed dormancy following maternal herbivory in Arabidopsis [PDF]

open access: yes, 2017
Maternal experience of abiotic environmental factors such as temperature and light are well known to control seed dormancy in many plant species. Maternal biotic stress alters offspring defence phenotypes, but whether it also affects seed dormancy ...

A VEL3 histone deacetylase complex establishes a maternal epigenetic state controlling progeny seed dormancy

open access: yesNature 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.

Understanding lolium rigidum seeds: The key to managing a problem weed? [PDF]

open access: yes, 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.

Setaria faberi Seed Heteroblasty Blueprints Seedling Recruitment: II. Seed Behavior in the Soil [PDF]

open access: yes, 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 ...

Seed dormancy revisited: Dormancy‐release pathways and environmental interactions

open access: yesFunctional 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

Environmental Regulation of Weed Seed Dormancy and Germination

open access: yesSeeds, 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 ...

Anthropogenic seed dispersal: rethinking the origins of plant domestication

open access: yes, 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

Polymorphic homoeolog of key gene of RdDM pathway, ARGONAUTE4_9 class is associated with pre-harvest sprouting in wheat (Triticum aestivum L.). [PDF]

open access: yesPLoS 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.

Tanned or burned: the role of fire in shaping physical seed dormancy. [PDF]

open access: yesPLoS 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.
