Figure 1: Development of phyllosphere community structure on greenhouse-grown Arabidopsis thaliana plants over a 73 day time series. (a) Phyllosphere communities follow a clear trajectory in membership from young plants to mature plants, and are distinct from the airborne inoculating community (PCoA plot using the Jaccard beta-diversity index). Arrows are in the direction of increasing time. Bubbles outlined in blue represent air microbes, and bubbles outlined in green represent plant-associated microbes. Bubble centroids are equal to the mean, and bubble diameter is proportional to the standard error of the mean. (b) The Morisita-Horn abundance-based metric of community composition indicate that plants in close spatial association (sharing the same experimental tray) have more similar microbial abundance profiles. Bubbles outlined in green and orange (Tray 1, green; Tray 2, orange) represent individual plants while bubbles outlined in blue represent averages across replicate air samples. Note the high percentage of variance explained by each axis. Separation of trays from air communities is mainly on the PC1 axis, explaining 32% of total variance. Separation of Tray 1 plant associated microbes from Tray 2 associated microbes is mainly on the PC2 axis, which explains 24% of total variance. Analysis performed using QIIME (Caporaso et al. 2010).
