Characterisation of dormancy cycling responses to environmental signals in contrasting Arabidopsis thaliana ecotypes [PDF]

open access: yes
Seed dormancy is an important trait refined by evolution, to aid survival in adverse environments and to time germination and thereby select the correct habitat and climate space for subsequent plant growth and reproduction.

Germination behaviour after storage of caper seeds

open access: yes, 2006
[EN] This five-year study (1999-2003) was designed to analyse the effects of the duration of the storage period on the viability and germination of caper seeds. Seeds were stored at 7 degrees C until the tests were conducted.

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

The influence of the caruncle on the germination of castor seed under high salinity or low soil water content

open access: yes, 2012
The caruncle is a structure present in the micropylar region of Euphorbiaceae seeds. This structure has the ecological function of promoting seed dispersal by ants (myrmecochory), but it is debated whether it also has an agronomical importance ...

Floral traits and hermaphrodite abundance shape female advantage in a gynodioecious plant

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Gynodioecy is maintained through female advantage in seed fitness that depends on the sex ratio of a population. We hypothesized that females of Silene acaulis would exhibit floral traits associated with elevated outcross pollination and that sex ratio would impact pollen limitation and inbreeding depression such that female advantage ...

Germination and vigor of soybean seed produced under different agro-meteorogical conditions [PDF]

open access: yesJournal on Processing and Energy in Agriculture, 2011
International seed trade considers seed germination as the main indicator of the seed quality. Different results of seed germination under laboratory conditions and emergence in the field encouraged the development of the concept of the seed vigor and ...

Revisiting Securidaca longipedunculata Seed Oil: Applying NMR and Mass Spectroscopy to Confirm the Presence of 2‐Acetyl‐1,3‐Diacyl–sn‐Glycerols and Conjugated Hydroxydienoic Fatty Acids

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.

A histone methyltransferase inhibits seed germination by increasing PIF1 mRNA expression in imbibed seeds

open access: yes, 2014
Phytochrome-interacting factor 1 (PIF1) inhibits light-dependent seed germination. The specific function of PIF1 in seed germination is partly due to its high level of expression in imbibed seeds, but the associated regulatory factors have not been ...

Kikuyu grass clippings as a bioeconomy feedstock: influence of pyrolysis conditions on biochar properties and its effect on the growth of Swiss chard

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The integration of urban organic waste streams into the bioeconomy is critical for advancing the water–food–energy nexus. Grass clippings, an abundant and underutilized municipal residue, represent a promising feedstock for producing value‐added materials.

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

open access: yesBMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...
