The soil seed bank can buffer long-term compositional changes in annual plant communities [PDF]
, 2020 Ecological theory predicts that the soil seed bank stabilises the composition of annual plant communities in the face of environmental variability. However, long-term data on the community dynamics in the seed bank and the standing vegetation are needed to test this prediction.

The MKKK62-MKK3-MAPK7/14 module negatively regulates seed dormancy in rice
Rice, 2019 Background Seed dormancy directly affects the phenotype of pre-harvest sprouting, and ultimately affects the quality and yield of rice seeds. Although many genes controlling seed dormancy have been cloned from cereals, the regulatory mechanisms ...

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.

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 Coat Development and Dormancy [PDF]
, 2007 Two major types of dormancy mechanisms exist: embryo dormancy where the agents inhibiting germination are inherent to the embryo, and coat-imposed dormancy where inhibition is conferred by the seed envelopes (Bewley, 1997). Generally, complex interactions between the embryo and covering structures determine whether a seed will germinate.

Seed dormancy and germination - Emerging mechanisms and new hypotheses
Frontiers in Plant Science, 2014 Seed dormancy has played a significant role in adaptation and evolution of seed plants. While its biological significance is clear, molecular mechanisms underlying seed dormancy induction, maintenance and alleviation still remain 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.

Agronomy Journal, Volume 114, Issue 6, Page 3544-3553, November/December 2022., 2022 Abstract Bermudagrass [Cynodon dactylon (L.) Pers.] is one of the most widely cultivated turfgrass species throughout the world. It has several important attributes, such as heat and drought tolerance, and one big disadvantage, which is susceptibility to cold temperatures.

American Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022 Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.
