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

Clustering analysis of the 18S rRNA gene clone libraries.
Dendrogram based on a hierarchical clustering analysis of the 18S rRNA gene clone libraries, constructed using the squared Euclidean distance similarity and Ward linkage procedures.
Figure 2.
Phylogenetic tree of the Fungi sequences.
Phylogenetic tree of the Fungi sequences recovered from the eight 18S rRNA gene clone libraries, constructed using the neighbor-joining method with the Kimura two-parameter model for nucleotide change. The Ascomycota and Basidiomycota which were just denoted the phylogenetic positions in this tree, presented in other separate phylogenetic trees. The libraries OTUs occurred were labeled. Scale bar, 0.1 substitutions per nucleotide position. Bootstrap values (100 replicates) above 60% are indicated at the nodes. The tree was rooted using the sequence related to Guillardia theta (X57162).
Figure 3.
The clone abundance analyses of the fungal orders or phylotypes.
The clone abundance analyses of the fungal orders or phylotypes which showed succession changes in populations with continuous cropping cycles. (The clone abundance was calculated as: (m1/M × 100, where m1 is the number of related clones detected in the libraries for the same cropping cycle and M is the total number of clones in the same libraries.).
