“…Concerning biological seed properties, the assessment of microbial communities associated with bean seeds within the same field experiment showed that these microbial assemblages, in particular their fungal component, were influenced by the seed crops’ environments within two years of multiplication [43]. Although there is increasing evidence for the interdependence of plants and their microbial communities, especially microbial life associated to plant roots [44,45,46], the effect of microbial communities of seeds on plant phenotypes is not well-known [43,47]. …”

Recognizing both the stakes of traditional European common bean diversity and the role farmers’ and gardeners’ networks play in maintaining this diversity, the present study examines the role that local adaptation plays for the management of common bean diversity in situ. To the purpose, four historical bean varieties and one modern control were multiplied on two organic farms for three growing seasons. The fifteen resulting populations, the initial ones and two populations of each variety obtained after the three years of multiplication, were then grown in a common garden. Twenty-two Simple Sequence Repeat (SSR) markers and 13 phenotypic traits were assessed. In total, 68.2% of tested markers were polymorphic and a total of 66 different alleles were identified. FST analysis showed that the genetic composition of two varieties multiplied in different environments changed. At the phenotypic level, differences were observed in flowering date and leaf length. Results indicate that three years of multiplication suffice for local adaptation to occur. The spatial dynamics of genetic and phenotypic bean diversity imply that the maintenance of diversity should be considered at the scale of the network, rather than individual farms and gardens. The microevolution of bean populations within networks of gardens and farms emerges as a research perspective.

“…This will allow researchers to define a core microbiota associated to specific seed genotypes. Studying the stability of this core seed microbiota to biological disturbances (or invasion) due to seed transmission of plant pathogens is a first step for designing biocontrol-based strategies [16].…”

“…In contrast, analyses of microbiota associated with other plant habitats such as the anthosphere [11], the carposphere [12][13][14][15], the seed habitat [16] and the spermosphere [17 ,18] have been relatively less studied. Nonetheless, these habitats are important for plant fitness since they are directly related to the production of offspring and then potentially associated to vertical transmission of the plant microbiota.…”

Seeds are involved in the transmission of microorganisms from one plant generation to another and consequently act as the initial inoculum for the plant microbiota. The purpose of this mini-review is to provide an overview of current knowledge on the diversity, structure and role of the seed microbiota. The relative importance of the mode of transmission (vertical vs horizontal) of the microbial entities composing the seed microbiota as well as the potential connections existing between seed and other plant habitats such as the anthosphere and the spermosphere is discussed. Finally the governing processes (niche vs neutral) involved in the assembly and the dynamics of the seed microbiota are examined.

“…Some of these associated microorganisms contribute to plant health, plant growth, and seed survival while others are detrimental (Barret et al 2016;Saikkonen et al 2016). Seeds can facilitate the dispersal of microorganisms, providing for early colonization of a new plant generation.…”
