They improve seedling \ngrowth by enhancing plant nutrient uptake, modulating stress-related \nphytohormone production, and targeting pests and pathogens with \nantibiotics. Seed endophyte composition can be influenced by \npollination, plant cultivar, and soil physicochemical conditions. \nHowever, the effects of plant community richness on seed endophytes are \nunknown. To investigate the effects of increasing plant species richness\n on the diversity and composition of the seed microbiome, we made use of\n a well-established long-term biodiversity experiment in Germany (The \nJena Experiment). We sampled seeds from different <em>Plantago lanceolata<\/em>\n blossoms in a plant diversity gradient ranging from monoculture to 16 \nspecies mixtures. The seeds were surface sterilized to remove seed \nsurface-associated bacteria and subjected to a metabarcoding approach to\n assess bacterial community structure.<\/p>\n\n\n\n<h3>Results<\/h3>\n\n\n\n<p class=\"justify\">Our  data indicate a very stable core microbiome, which accounted for more  than 90% of the reads and was present in all seeds independent of the  plant richness level the seeds originated from. It consisted mainly of  reads linked to <em>Pseudomonas rhizosphaerae, Sphingomonas faeni<\/em> and <em>Pirellulla spp<\/em>.  9% of the obtained reads were not part of the core microbiome and were  only present in plots of specific diversity levels. The number of unique  ASVs was positively correlated with plant richness. Interestingly, most  reads described as non-core members belonged to the same genera  described as the core microbiome, indicating the presence of different  strains or species with possibly different functional properties  important for seed performance.<\/p>\n\n\n\n<h3>Conclusion<\/h3>\n\n\n\n<p class=\"justify\">Our data indicate that <em>Plantago lanceolata<\/em>  maintains a large seeds core microbiome across the plant richness  gradient. However, the number of unique ASVs increases alongside the  plant community richness, indicating that ecosystem biodiversity also  mitigates diversity loss in seed endophytes.<\/p>\n\n\n\n<h3>Reference<\/h3>\n\n\n\n<p>de Souza, Y.
