(A) The fungal OTU accumulation curve for all 1026 samples 4 and for 252 leaf, 252 root, 252 rhizosphere and 270 soil samples. For all 1026 samples, the OTU accumulation curve reached a plateau of 986 of 5 1070 taxa after just 250 samples. (B) The frequency of fungal OTUs found in as few as 1 to as many as 1026 of all 1026 communities sampled. 6 For specific compartments, many species were found in all 252 or 270 samples. The the y axis is the same for all and separate compartments. 7 Source data are provided as a Source Data file 8

25 Supplementary Fig. 5 Fungal community dynamics detected from a compositional dataset 26 (dataset 2). Principal component (PC) analysis of fungal community Aitchison distance with 27 permutational analysis of variance (PERM ANOVA) showing significant association of fungal 28 community composition with, in order of importance, compartment, time period, drought 29 treatment and sorghum cultivar (*P < 0.05; *** P < 0.001). Note the result of principal 30 coordinate (PCo) analysis of Bray-Curtis dissimilarity (dataset 1) is presented in Fig. 2A. Source 31 data are provided as a Source Data file. 32

33 Supplementary Fig. 6 Fungal functional guilds affected by sorghum compartment showing 34 significantly biased occurrences of yeasts and pathogenic fungi toward leaf, and biased 35 occurrences of arbuscular mycorrhizal and saprotrophic fungi toward root, rhizosphere and 36 planted soil. Ternary plot demonstrating the distribution fungal operational taxonomic units 37 (OTUs) (A) among leaf, root and rhizosphere, (B) among unplanted soil, planted soil and leaf, 38 (C) among unplanted soil, planted soil and root, and (D) among unplanted soil, planted soil 39 and rhizosphere. The circle size corresponds to OTU abundance (sqrt transformed). To 40 simplify, the plots A-D only kept OTUs whose abundances were significantly (P < 0.0001) 41 different among different compartments. Plots containing both significant and non-42 significant (NS) OTUs are shown in plots E-H. Source data are provided as a Source Data file. 43

44 Supplementary Fig. 7 Succession of the fungal community by compartment and plot. 45 Temporal distance (in weeks between sampling times) in relation to Bray-Curtis community 46 dissimilarity by Mantel testing. Note the relatively large variance in Bray-Curtis community 47 dissimilarity over small temporal distances in leaves. Source data are provided as a Source 48 Data file. 49

50 Supplementary Fig. 8 Temporal turnover of compositional variance. Principal coordinate 51 (PCo) plots demonstrating the compositional variance as measured by Simpson metric within 52 every week of three treatments and four compartments. ***P < 0.001 in beta dispersion 53 analysis; *** P < 0.001 in permutational analysis of variance (Perm ANOVA). Note that the 54 control results are also presented in Fig. 3B. Note the Simpson metric differs from the Bray-55 Curtis and Jaccard metrics in that it is free from richness variance. Source data are provided 56 as a Source Data file.57

59 Supplementary Fig. 9 Temporal turnover of compositional variance between specified pairs 60 of treatments. Heatmaps showing mean pairwise Simpson dissimilarity between time points 61 between control and control, between control and pre-flowering drought, and between 62 control and post-flowering drought. The largest turnover between sampling times is seen in 63 leaves between the first week and subsequent time points, in roots between weeks 1-5 and 64 weeks 11-17, and in the rhizosphere between weeks 1-7 and weeks 13-16; soils did not show 65 significant turnover. The green dashed lines are flowering times. The blue dashed line is the 66 time that pre-flowering drought was ended and water irrigation resumed. Source data are 67 provided as a Source Data file. 68

69 Supplementary Fig. 10 Threshold indicator taxa analyses (TITAN) showing individual OTU 70 abundances in response to sampling time in the four compartments.

Supplementary Fig. 13 Re-analysis rice root bacteria data showing no beta dispersion of the turnover component of compositional variance. This 87
result is found despite significantly higher compositional variance early in the rice life cycle as compared to later stages as measured by the 88
Jaccard dissimilarity. *** Padj < 0.001; ns: not significant; in beta dispersion analysis. Note the P values are adjusted by Bonferroni method to 89
avoid type I error of multiple comparisons. Source data are provided as a Source Data file.90

Supplementary Fig. 14 Sorghum cultivar effect on fungal OTU abundance and community composition in leaf, root, rhizosphere and soil. (A) 93
Fungal OTUs showing significantly different abundance between sorghum cultivars BTx642 and RTx430. OTUs above a false discovery threshold 94
[green horizontal line with P < 0.00005 (0.05/1070 OTUs) or -log (P) = 10] show significant bias between the two cultivars. The symbol size 95
corresponds to OTU abundance (log transformed) and color corresponds to fungus functional guild. Note that cultivar effects were seen on OTU 96
abundance in root and rhizosphere, but not in leaf nor soil. Differences in fungal community composition between the two sorghum cultivars, 97
are given as R2 as determined by permutational analysis of variance (PERM ANOVA). (B) Divergent temporal abundance of Fungal OTUs with 98
significant cultivar effects (seen in A) can occur throughout sorghum development, e.g., at early (OTU29), late (OTUs 24, 26, 34, 207), or the 99
middle time points (OTU19, 20). Source data are provided as a Source Data file. 100

Supplementary Fig. 20 Temporal dynamics of fungal compositional variance measured by Fst. 123
According to Gilbert and Levine 34
, given the observed relative abundance, Fst is a measure 124
that standardizes the variation among patches for each species relative to the maximum 125
variation possible. Note due to the heteroskedasticity, curve fitting is not carried out for this 126
dataset. Source data are provided as a Source Data file. 127

Supplementary Fig. 21 (A) Principal coordinate (PCo) plots of beta mean nearest taxon 130
distanc (βMNTD) for fungal communities. The first week leaf samples are phylogenetically 131
distinct from other samples, as demonstrated by PCo analysis of βNTI of fungal communities. 132
(B) PCo plots of fungal communities in unplanted soil and first week samples. Replicate 133
communities of the soil and rhizosphere for these first two time points (TP00 and TP01) are 134
more similar than are the communities of leaves or roots for just the second time point. 135
Source data are provided as a Source Data file. 136

137
Supplementary Fig. 22 Evidence of the absence of distance decay of fungal community 138
dissimilarity, as seen from the nearly flat slope of the correlation between geographic 139
distance and Bray-Curtis dissimilarity of fungal communities of each week and each 140
compartment. Overall, the null hypothesis of no relationship between geographic distance 141
and community dissimilarity, while taking into account multiple testing [P = 0.003 (0.05/17)], 142
cannot be rejected for any leaf, root or rhizosphere sample, or for 15 of 17 soil samples 143
(excepting weeks 12 and 16). Thus, although there is an association at two time points 144
between community dissimilarity and distance for post-flowering soil, the R is low (0.320-145
0.372) and this effect is seen weeks after our detection of stochasticity in leaves and roots. 146

Note the week 8 165 and week 17 are differentiated by circle and triangle shapes, and the three treatments are distinguished by colors.

OTUs above the green horizontal line [-log (P) = 10] are significant biased 170 fungi detected by P < 0.00005. The symbol size corresponds to OTU abundance (log transformed). This figure is the same as Fig. 4A-B, except 171 that genus names are provided for significantly different OTUs. Source data are provided as a Source Data file. 172
