“…However, dormant microbial communities within soil have also been hypothesized to be powerful pools of potential diversity and can respond rapidly to changes in environmental inputs (Joergensen and Wichern , Kearns and Shade , Nelson et al. ). Much of the diversity at deeper soil depths consisted of unknown taxa.…”

“…However, the mechanisms underlying microbial migration into seeds have only been studied with a limited number of pathogenic bacteria (Donati et al, 2018). Although microorganisms within seeds are confined to seed coats, they are transferred to the soil through cotyledon defoliation and root development after seed germination, which serves as a basis for the establishment of the soil microbial community in association with the indigenous soil microbiota (Nelson et al, 2018;Fig. 1).…”

Summary Since the discovery of the role of microbes in the phytobiome, microbial communities (microbiota) have been identified and characterized based on host species, development, distribution, and condition. The microbiota in the plant rhizosphere is believed to have been established prior to seed germination and innate immune development. However, the microbiota in seeds has received little attention. Although our knowledge of the distribution of microbiota in plant seeds and rhizosphere is currently limited, the impact of these microbiota is likely to be greater than expected. This minireview suggests a new function of microbial inheritance from the seed to root and from the first generation of plants to the next. Surprisingly, recruitment and accumulation of microbiota by biotic and abiotic stresses affect plant immunity in the next generation through plant–soil feedback and soil memory. To illustrate this process, we propose a new term called ‘microbiota‐induced soil inheritance (MISI).’ A comprehensive understanding of MISI will provide novel insights into plant–microbe interactions and plant immunity inheritance.

“…Germinating seeds then release molecules that attract soil microbes, surrounding themselves with a microbiologically active soil area called the spermosphere (Nelson, 2004; Schiltz et al , 2015). The emergence of the plant radicle creates cracks in the seed tegument, enabling microbes to colonize internal tissues (Nelson et al , 2018). These events lead to intense biotic interactions among microorganisms (Nelson, 2004) and drastic changes in seed microbiota composition and function (Ofek et al , 2011; Yang et al , 2017; Torres-Cortés et al , 2018).…”

Trees, as foundation species, play a pivotal role in the species interaction networks that constitute forest ecosystems. From the seed stage, they interact with microbial communities that affect their growth, health and fitness. Despite their eco-evolutionary importance, the processes shaping seed microbial communities in natural forests have received little attention.• To unravel these processes, we analyzed the microbial communities of seeds collected in populations of sessile oak (Quercus petraea) growing along elevation gradients. We focused on the fungal communities as this group includes seed pathogens. Ecological processes shaping the communities were quantified using joint species distribution models.• Fungi were present in all seed tissues, including the embryo. Fungal communities differed significantly among oak populations along the elevation gradients, and among mother trees within the same population. These maternal effects remained significant after seed fall, despite colonization by fungal species on the ground. Associations between tree pathogens and their antagonists were detected in the seeds.• Our results demonstrate that both maternal effects and environmental filtering shape seed microbial communities of sessile oak. They provide a starting point for future research aimed at identifying the seed extended phenotypic traits that influence seed dispersal and germination, and seedling survival and growth across environments.
