叶子表面生活着大量细菌，这些叶际细菌对植物健康具有重要影响。然而，我们目前对树叶上的细菌多样性以及叶际群落结构的种间和种内变异性的了解有限。我们使用条形码焦磷酸测序技术来表征美国科罗拉多州博尔德市 56 种树种叶子的细菌群落，量化其中 10 个树种的细菌群落个体内和个体间的变异性。我们还研究了全球多个地点黄松叶际群落的地理变异性。个别树种具有高水平的细菌多样性，并且树之间的群落组成存在相当大的差异。细菌群落的组织模式可以根据树木的相关性进行预测，因为树木系统发育和细菌群落系统发育之间存在显着的对应关系。细菌群落组成的种间变异超过了种内变异，这种模式甚至在各个大陆上都存在，我们观察到黄松针上细菌群落的地理差异最小。
Large populations of bacteria live on leaf surfaces and these phyllosphere bacteria can have important effects on plant health. However, we currently have a limited understanding of bacterial diversity on tree leaves and the inter- and intra-specific variability in phyllosphere community structure. We used a bar-coded pyrosequencing technique to characterize the bacterial communities from leaves of 56 tree species in Boulder, Colorado, USA, quantifying the intra- and inter-individual variability in the bacterial communities from 10 of these species. We also examined the geographic variability in phyllosphere communities on Pinus ponderosa from several locations across the globe. Individual tree species harboured high levels of bacterial diversity and there was considerable variability in community composition between trees. The bacterial communities were organized in patterns predictable from the relatedness of the trees as there was significant correspondence between tree phylogeny and bacterial community phylogeny. Inter-specific variability in bacterial community composition exceeded intra-specific variability, a pattern that held even across continents where we observed minimal geographic differentiation in the bacterial communities on P. ponderosa needles.
