The spermosphere is the zone surrounding seeds where interactions between the soil, microbial communities and germinating seeds take place. The concept of the spermosphere is usually only applied during germination sensu stricto. Despite the transient nature of this very small zone of soil around the germinating seed, the microbial activities which occur there may have long‐lasting impacts on plants. The spermosphere is indirectly characterized by either (i) seed exudates, which could be… 

Soybean and cotton spermosphere soil microbiome shows dominance of soil-borne copiotrophs

The spermosphere is the transient, immediate zone of soil around imbibing and germinating seeds. It represents a habitat where there is contact between seed-associated microbes and soil microbes, but

Mechanism of Interaction of Endophytic Microbes with Plants

In this chapter, the current understanding concerning the spermosphere and endophytic microbes that have been isolated from seeds of different plant species are focused on.

Toward a Molecular Understanding of Rhizosphere, Phyllosphere, and Spermosphere Interactions in Plant Growth and Stress Response

Abstract The rhizosphere and phyllosphere are the below- and above-ground microbial ecosystems of plants. Interactions between the rhizosphere and phyllosphere shape the plant-microbiome environment,

Anthosphere Microbiome and Their Associated Interactions at the Aromatic Interface

This chapter was written to provide an overview of the different interfaces, in particular, the anthosphere region of the phyllosphere, to attain sustainability in plant conservation, food, and agriculture.

Studying Seed Microbiomes.

This chapter provides a combination of methods that are established and optimized for the analysis of the seed microbiome, including methods to activate and cultivate dormant seed microbiota, and analyze microbiota in germinated seeds.

Endophytic microbiome variation at the level of a single plant seed

This study reports a protocol for extracting metagenomic DNA from an individual seed with minimal disruption of host tissue, and applies this protocol to quantify the 16S rRNA V4 and ITS2 amplicon composition and variability for individual seeds harvested from replicate common bean plants grown under standard, controlled conditions to maintain health.

More than words: the chemistry behind the interactions in the plant holobiont.

The aim of this review is to present the latest findings on the dazzlingly diverse arsenal of molecules that efficiently mediate specific micro be-microbe and microbe-plant communication pathways during plant development and on different plant organs.

Single Seed Microbiota: Assembly and Transmission from Parent Plant to Seedling

It is shown that initial bacterial abundance on seeds was not a good predictor of seedling transmission and that the identity of seed-borne taxa can impact seedling phenotype, which appears to be important for the early stages of plant development.

This review, which represents the first comprehensive synthesis of the literature on spermosphere biology, is meant to illustrate the unique nature of the sper atmosphere and how studies of interactions in this habitat may serve as useful experimental models for testing hypotheses about plant-microbe associations and microbial ecology.

Microbial community structure and function in the spermosphere as affected by soil and seed type

A study of the soil microbial community around germinating seeds was undertaken as a necessary first step in understanding the competition between the introduced plant-beneficial bacteria and the indigenous microbial community.

Beneficial bacteria of agricultural importance

Plant growth-promoting rhizobacteria (PGPR) are potential agents for the biological control of plant pathogens and a biocontrol strain should be able to protect the host plant from pathogens and fulfill the requirement for strong colonization.

Rhizosphere and Root Colonization by Bacterial Inoculants and Their Monitoring Methods: A Critical Area in PGPR Research

Recent developments in techniques for studying rhizobacterial communities and detection and tracking systems of inoculated bacteria are important in future application and assessment of effectiveness and consistent performance of microbial inoculants in crop production and protection.

Colonization of cucumber seeds by bacteria during germination.

Simple, even passive processes may determine the initial stage of plant-microbe association during seed germination, prior to extension of the primary root, which is a unique phase in the plant life cycle, with respect to its interaction with the below-ground microbiome.

Abstract The production of hydrophilic mucilages by the seed coat or pericarp, which are released upon seed hydration, is a commonly found adaptation in angiosperms, known as myxodiaspory. These are

Plant-driven selection of microbes

The general part of the manuscript is followed by the more detailed presentation of specific examples for the selection and interaction of roots and microbes, such as in the rhizosphere of strawberry, potato and oilseed rape, where the soil-borne plant pathogen Verticillium dahliae can cause high yield losses; the potential of biocontrol by specific constituents of the Rhizosphere microbial community is demonstrated.

Bacterial Origin and Community Composition in the Barley Phytosphere as a Function of Habitat and Presowing Conditions

The results demonstrate the application of culture-independent, molecular techniques in assessment of Rhizosphere bacterial populations and the importance of the indigenous soil population in colonization of the rhizosphere.
