Quantitative data relevant to plant surface microbiology extracted from Fig. 10A by CMEIAS image analysis Measurement feature Type of analysis Value Number of cells Microbial abundance 138 Avg. cell biovolume (mm 3 ) Microbial abundance 0.17 Avg. cell biomass C (fg) Microbial abundance 34.66 Avg. cell biosurface area (mm 2 ) Microbial abundance 1.72 Cumulative bacterial biovolume (mm 3 ) Microbial abundance 23.91 Cumulative bacterial biomass C (fg) Microbial abundance 4783.18 Cumulative bacterial biosurface area (mm 2 ) Microbial abundance 237.86 Cumulative area covered by bacteria (mm 2 ) Microbial abundance 60.25 Avg. first nearest neighbor distance (mm) Plotless spatial 0.84±0.30 distribution Avg. second nearest neighbor distance (mm) Plotless spatial 1.10±0.32 Average aggregation (cluster) index (mm –1 ) Plotless spatial 1.31±0.38 distribution Holgate’s A value of spatial randomness Plotless spatial 0.622 distribution =clumped Significance value of Holgate’s A (p) Plotless spatial 0.001 distribution Spatial density of bacteria (cells/mm 2 ) Plot-based spatial 427,245 distribution Microbial cover (%) Plot-based spatial 18.7 distribution Uncovered root surface area (%) Plot-based spatial 81.3 distribution biology that were extracted from this same image, eight features that measure microbial abundance, and seven (four plot-less plus three plot-based) features that measure their spatial distribution. The Aggregation (Cluster) Index is a plot-less spatial distribution measurement feature that we have introduced, equal to the inverse of the first nearest neighbor distance (Dazzo et al. 2003). The Holgate’s method for plot-less spatial analysis is a statistical test for spatial randomness requiring that n random points be selected and that the distance to the two nearest individuals be measured. This method computes Holgate’s A, a measure of aggregation. Values of A are 0.5 for randomly spaced populations, >0.5 for clumped populations, and 0.5, their spatial distribution is clumped, and the Z-test for spatial randomness is rejected at the statistically significant level of 99.9 %. Definitive quantitative spatial distribution data acquired by computer-assisted microscopy!
