由于生产大而显眼的花的成本可能很高，自花授粉或无性繁殖的植物可能会因为吸引传粉者而失去特征。然而，一些植物尽管不依赖传粉者授粉受精，但仍然开出显眼的花，这表明接待访花的好处被忽视了。在这里，我们介绍了游客介导的微生物传播作为接待花卉游客的潜在好处。最近的研究表明，各种微生物生活在植物表面或植物组织中，这些微生物对寄主植物有很大的好处。动物花卉访客驱散了这些微生物。由于一些微生物可以迁移到种子中，通过访客进行的增强传播可以调节下一代的微生物群落。通过访花传播微生物可能会增加接受微生物对种子的互惠作用的机会，并增加种子微生物群落的变异性，从而提高植物的适合性。我们可以通过比较微生物群落和实验排除访客的花和自然动物访问的对照花的种子的表现来检验这一假设。进一步的灭菌或微生物接种试验可能证实特定的类群或微生物群落结构对观察到的种子性能影响的贡献。
Since the production of large and conspicuous flowers can be costly, self‐pollinated or asexually reproducing plants are expected to lose characters for pollinator attraction. However, some plants still produce conspicuous flowers despite not relying on pollinators for fertilization, suggesting overlooked benefits of receiving flower visitors. Here, we present visitor‐mediated microbial dispersal as a potential benefit of receiving flower visitors. Recent studies revealed that diverse microbes inhabit plant surfaces or plant tissues and that these microbes substantially benefit host plants. Animal flower visitors disperse these microbes. Since some microbes can migrate to seeds, the enhanced dispersal via visitors can modulate microbial communities of the next generations. Microbial dispersal via flower visitors may improve plant fitness via increased opportunities to receive microbes mutualistic for seeds and higher variances in seed microbial communities that function as “bet‐hedging.” We can test this hypothesis by comparing microbial communities and the performance of seeds from experimentally visitor‐excluded flowers and naturally animal‐visited control flowers. Further experiments with sterilization or microbe inoculation may confirm the contribution of specific taxa or microbial community structures to the observed effects on seed performances.
