Table 2.

Diversity indices for bacterial endophyte 16S rRNA gene sequences using genus-level groupings (95% similarity).

Diversity indices	All isolates	Bisle Ghat region	Mangaluru	Mysore
Number of isolates	75	34	38	3
Unique OTUs	16	13	8	2
Good's coverage (%)	79	62	79	33
Simpson's diversity index (1-D)	0.72	0.82	0.60	0.44
Shannon's diversity index (H')	1.88	2.10	1.33	0.64
SChao1	23	17	11	2

OTU, operational taxonomic unit.

S _Chao1 represent the expected number of OTUs present in an environment if sampling were complete.

Shannon's and Simpson's indices are measures of species diversity and both increase with increasing genetic diversity.
