TABLE 1.

Richness and alpha diversity of rhizosphere bacterial and fungal communities associated with root rot asymptomatic and symptomatic avocado trees.

	Observed OTUs	Shannon index (H’)	Simpson’s index (D)
Bacteria
Asymptomatic (n = 16)	888 ± 71	6.04 ± 0.04	0.99 ± 0.0001
Symptomatic (n = 14)	810 ± 82	5.92 ± 0.13	0.99 ± 0.003
Fungi
Asymptomatic (n = 2)	545	4.56	0.97
Symptomatic (n = 2)	574	4.81	0.97

Values represent the means ± SE. “n” represents the number of sequencing libraries. No significant differences were observed in bacterial alpha diversity metrics (P > 0.05, Mann-Whitney-Wilcoxon test).
