Table 1. Analysis of the clone libraries constructed over three continuous cropping cycles and representative growing stages of peanut.

Library	No.of clones	No. of total OTUs	No. of unique OTUs	% Coverage	No. of OTUs sharedby libraries fromsame cropping cycle	% shared OTUs
08S	99	29	12	87.9	10	34.5
08F	98	29	14	85.7		34.5
08B	100	25	13	87.0		38.5
08M	97	26	10	89.7		38.5
09S	99	35	22	77.8	18	51.4
09M	96	33	19	80.2		54.5
10S	103	38	20	80.1	22	57.9
10M	101	34	22	78.2		64.7

The coverage values were calculated as follows: [1−(n1/N)]×100, where n1 is the number of unique OTUs (frequency, 1) detected in the library and N is the total number of clones in the same library.
