众所周知，植物物候学取决于许多不同的环境变量，但土壤微生物群落很少被认为是开花时间的可能驱动因素。在这里，我们分别测试了四种自然存在的土壤微生物及其组成的土壤化学成分对拟南芥的野生近亲--狭叶羊草的开花物候和生殖适合度的影响。开花时间对微生物和不同土壤的非生物特性都很敏感；不同的土壤微生物区系也改变了对开花时间的选择模式。因此，土壤微生物可能对开花时间的表型可塑性和生境之间的差异选择做出贡献。我们还描述了一种将微生物组解剖成单个变异轴的方法，该方法可以帮助识别土壤中的丰度与开花时间相关的候选生物。这种方法广泛适用于寻找改变感兴趣的生物学特性的微生物群落成员。
Plant phenology is known to depend on many different environmental variables, but soil microbial communities have rarely been acknowledged as possible drivers of flowering time. Here we tested separately the effects of four naturally occurring soil microbiomes and their constituent soil chemistries on flowering phenology and reproductive fitness of Boechera stricta, a wild relative of Arabidopsis. Flowering time was sensitive to both microbes and the abiotic properties of different soils; varying soil microbiota also altered patterns of selection on flowering time. Thus, soil microbes potentially contribute to phenotypic plasticity of flowering time and to differential selection observed between habitats. We also describe a method to dissect the microbiome into single axes of variation that can help identify candidate organisms whose abundance in soil correlates with flowering time. This approach is broadly applicable to search for microbial community members that alter biological characteristics of interest.
