Table 2. Diversity indices of M. oxyfera-like bacteria in submerged P. crispus rhizosphere and non-rhizosphere sediments.

Sample	Sequence	OTU	Coverage	Shannon	Chao1
R	45	4	1.00	0.92	4
N1	47	6	0.94	1.14	9
N2	45	5	0.98	1.16	5
N3	50	5	0.96	0.73	6
N4	48	5	0.98	1.00	5
N5	44	4	0.98	0.80	4
Non	45	5	0.96	0.87	6

Note:

R and Non represent sediment samples in root and non-rhizosphere compartment, respectively; N1–N5 represent sediment samples taken from one to five mm of near-rhizosphere sub-compartments.
