(A) Rarefaction curves of OTUs clustered at < 97% sequence identity for 21 different rhizoshpere soil samples of corn seed production from 5, 10, 15, 20, 25, 30 and 30 years of continuous cropping. Uppercase of A, B, C, D, E, F and G represent 5, 10, 15, 20, 25, 30, and 30 years, respectively. The subscript below the letter represent three duplicates of the same cropping year. The OTUs reads of different samples are shown in different colors. (B) Flower graph of OTUs of different continuous cropping year. Uppercase A, B, C, D, E, F, and G represent 5, 10, 15, 20, 25, 30, 30 years, respectively. The core was the common OTUs for different treatment. (C) OTUs relative abundance curves for the OTUs in the 21 different corn seed production rhizoshpere soil samples from 5, 10,15, 20, 25, 30 and 30 (with field corn) years of continuous cropping. Uppercase A, B, C, D, E, F, and G represent 5, 10, 15, 20, 25, 30, and 30 years, respectively. The subscript below the letter represent three duplicates of the same cropping year. The OTUs reads of different samples are shown in different colors.
