Review: Time to wake up: Epigenetic and small-RNA-mediated regulation during seed germination (Plants)

Seed germination is a crucial step in plants' life cycle and has critical implications in ecological and agronomic contexts. Therefore, there has been an increasing interest in understanding the mechanisms that prevent or trigger this process. Here, Luján-Soto and Dinkova provide a thorough review of…

Experimental evidence of microbial inheritance in plants and transmission routes from seed to phyllosphere and root (Environ. Microbiol.)

All plant species are associated with a diverse yet distinct assemblage of microorganisms known as the microbiome. Traditionally, the environment is considered the primary source of these microbes. However, Abdelfattah and colleagues' fascinating research shows that seeds can act as vehicles to share…

Seed tolerance to post-fire temperature fluctuation of Cerrado legume shrubs with micromorphological implications ($) (Flora)

Legume seeds are typically physically dormant, meaning they have an impermeable seed coat that prevents water uptake. In fire-prone ecosystems, this dormancy is presumably broken when the seed coat is cracked due to being exposed to fire or the daily temperature fluctuations found in burnt sites. However,…

Seed enhancement technologies to improve germination and emergence of Australian native Poaceae (Seed Sci. Res.)

One of the most significant limitations in seed-based restoration projects is that some native species exhibit low recruitment in the field. As a result, various seed enhancement technologies (SETs) are being developed to improve germination and seedling emergence by facilitating access to nutrients…

The seed germination spectrum of alpine plants ($) (New Phytol.)

Alpine ecosystems include all the environments found above the treeline, the maximum elevation where trees can grow. These environments are known for their low temperatures, unstable substrates, and short growing seasons. However, while germination studies in this ecosystem can be traced back to…

Distribution of seed dormancy classes across a fire-prone continent: effects of rainfall seasonality and temperature (Ann. Bot.)

Seed dormancy controls germination so that it occurs under the most suitable conditions. Different dormancy classes achieve this by allowing germination in response to distinct environmental cues. In fire-prone ecosystems, species with physically dormant (PY) seeds benefit from fire since it breaks their…

Elevation filters seed traits and germination strategies in the eastern Tibetan Plateau (Ecography)

Mountains are extraordinary natural laboratories. They encompass a wide range of environments in a relatively small space, making them ideal for assessing how different environmental variables shape plant traits and communities. Here, Wang and colleagues evaluate how seed functional traits vary along…

Combinations of maternal-specific repressive epigenetic marks in the endosperm control seed dormancy (bioRxiv.)

H3K27me3 [K27 (Lysine 27) trimethylation on histone H3] and H3K9me2 are two epigenetic modifications that repress gene activity in plants. While they are typically present in different genomic regions, both marks are found in the seed endosperm. Here, Sato and colleagues show that this histone modification…

The first dormancy profile for a tropical montane forest community (Plant Biol.) ($)

Seed dormancy is a crucial mechanism to synchronize germination with the most suitable environmental conditions. Therefore, assessing its prevalence at the community level allows us to understand how plants adapt to their local environment. In this paper, Athugala and colleagues build the first dormancy…
