Physical Seed Dormancy in Legumes: Molecular Advances and Perspectives
PlantsPhysical dormancy of seeds is a form of dormancy due to the presence of an impermeable seed coat layer, and it represents a feature for plants to adapt to environmental changes over an extended period of phylogenetic evolution.

The role of the testa during the establishment of physical dormancy in the pea seed [PDF]
Annals of Botany, 2019 A water-impermeable testa acts as a barrier to a seed's imbibition, thereby imposing dormancy. The physical and functional properties of the macrosclereids are thought to be critical determinants of dormancy; however, the mechanisms underlying the maintenance of and release from dormancy in pea are not well understood.Seeds of six pea accessions of ...

A class II KNOX gene, KNOX4 , controls seed physical dormancy [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2016 Significance Physical dormancy, often called hardseededness, exists widely in higher plants. This adaptive trait allows plants to maintain a seed bank in soil, and thus survive unfavorable environmental conditions. The molecular mechanism of physical dormancy is largely elusive.

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 Germination in Cistus ladanifer: Heat Shock, Physical Dormancy, Soil Temperatures and Significance to Natural Regeneration [PDF]
Plants, 2019 Seeds of Cistus ladanifer experience bursts of germination following fires. The effects of heat shock from 10 °C to 150 °C on seed germination were investigated by final germination plus the number of days required for germination to start and ...

Dry versus wet dormancy: suspended lives of Bacillus subtilis versus Saccharomyces cerevisiae spores [PDF]
mSystemsDormant microbial spores provide one of the clearest and most extreme examples of how cells can pause life for extended periods and then reliably restart it. Although bacterial and fungal spores are often grouped under “dormancy,” the physical strategies

Testa structure in Erythrina speciosa (Leguminosae): the role of the mucilaginous stratum in the acquisition of physical dormancy [PDF]
Acta Botânica Brasílica, 2020 Seeds of Erythrina speciosa (Papilionoideae) exhibit physical dormancy, but evidence has suggested that the proportion of impermeable seeds increases with storage. There are no records of structural variation in the testa of E.

Acid Scarification Completes the Germination of Hovenia dulcis Seeds
Agronomy, 2022 Seeds have been reported to have a combination of physical and physiological dormancy. However, this study revealed that H. dulcis seeds only have physical dormancy. The water absorption of the seeds after different periods of sulfuric acid scarification

Dormancy in seeds of brazilian cerrado and dense Ombrophilous forest
Biodiversidade Brasileira, 2023 The Cerrado and the Dense Ombrophilous Forest are important brazilian biomes that together cover more than half of the country's territory. They have a vast and rich plant diversity which often has a block in the germination process called dormancy ...
