TL;DR: The role of seed-associated microorganisms, and especially seed endophytic bacteria, still is underestimated, but these associations could be beneficial for germination and seedling establishment as seed endophical bacteria are already present in these very early plant growth stages.

Abstract: Summary
Although the importance of plant-associated microorganisms for plant growth and health was getting more recognition recently, the role of seed-associated microorganisms, and especially seed endophytic bacteria, still is underestimated. Nevertheless, these associations could be beneficial for germination and seedling establishment as seed endophytic bacteria are already present in these very early plant growth stages. Moreover, bacteria with beneficial characteristics can be selected by the plants and could be transferred via the seed to benefit the next generation. In this paper, the current literature concerning bacterial endophytes that have been isolated from seeds of different plant species is reviewed. Their colonization routes, localization inside seeds and mode of transmission as well as their role and fate during germination and seedling development are discussed. At the end, some examples of bacterial seed endophytes with applications as a plant growth-promoting or biocontrol agent are given.

Bacterial endophytes in agricultural crops
TL;DR: Historically, endophytic bacteria have been thought to be weakly virulent plant pathogens but have recently been discovered to have several beneficial effects on host plants, such as plant growth promotion and increased resistance against plant pathogens and parasites.

Plant growth-promoting bacteria in the rhizo- and endosphere of plants: Their role, colonization, mechanisms involved and prospects for utilization
TL;DR: The individual steps of plant colonization are described and the known mechanisms responsible for rhizosphere and endophytic competence are surveyed to better predict how bacteria interact with plants and whether they are likely to establish themselves in the plant environment after field application as biofertilisers or biocontrol agents.
Feedback with soil biota contributes to plant rarity and invasiveness in communities.
TL;DR: The results indicate that plants have different abilities to influence their abundance by changing the structure of their soil communities, and that this is an important regulator of plant community structure.

Bacterial Endophytes and Their Interactions with Hosts
TL;DR: Molecular analysis showed that plant defense responses limit bacterial populations inside plants, and delivery of endophytes to the environment or agricultural fields should be carefully evaluated to avoid introducing pathogens.
