Commentary: seed bacterial inhabitants and their routes of colonization

Seeds host bacterial inhabitants but only a limited knowledge is available on which taxa inhabit seed, which niches could be colonized, and what the routes of colonization are. Within this commentary, a discussion is provided on seed bacterial inhabitants, their taxa, and from where derive the seed colonizers. Seeds/and grains host specific bacteria deriving from the anthosphere, carposphere, or from cones of gymnosperms and inner tissues of plants after a long colonization from the soil to reproductive organs.
