DGGE profiles of PCR-amplified 18S rRNA gene-internal transcribed spacer.

<p>(A) Fragments in a denaturing from 30% to 70% gradient gel. F1-F6 represents sequenced bands in the fungal community DGGE gel. (B)Redundancy Analysis (RDA) of fungal community in the sediments from each six sampling sites (site A, site B, site C, site D, site E, site F) in the Zhou cun drinking water reservoir, eastern China. Samples are represented by open circles and capital letters refer to the sampling sites. Numbers in brackets represent the percentage of variation explained by each factor, RDA1 explains 35.40% of the variance of the data and RDA2 explains 16.00% of the variance in the data, respectively. Significant factors for variation extracted from environmental data (sediment urease and protease activity) are given as vectors.
