Diversity of culturable bacteria within different samples.

<p>Diversity of culturable bacteria within different samples.</p

Four-way Venn diagram depicting the shared and unshared T-RFs between the four niches.

<p>Profiles obtained with <i>Hinf</i> I (A) and <i>Hae</i> III (B) endonucleases from samples of both vineyards <i>I</i> and <i>II</i>. Numbers in parenthesis indicate the total number of TRFs for each niche.</p

Shannon–Weaver diversity and Evenness indices from 16S rRNA gene T-RFLP profiles.

<p>Values in brackets represent standard deviation (n = 3). * denotes homogenous groups revealed by post-hoc tests (Tukey's HSD multiple-comparison test, p <0.001) based on the comparisons between the (E) and (H') values of different samples (n = 6).</p

Comparison of bacterial colonization patterns in different ecosystems.

<p>Principal-component analysis based on bacterial community structure, assessed by 16S rRNA gene T-RFLP (including TRF size and relative abundance data), using Hinf I digest, from vineyard I (a) and vineyard <i>II</i> (b); the amount of variability accounted for by each factor is shown on the axes. (c) Clustering obtained by the hierarchical UPGMA method based on the arithmetical complement of the Jaccard similarity index of samples from both vineyards. Triangles (Δ) indicate bark samples; (◊) diamonds indicate leaf samples, squares (□) indicate soil samples; circles (○) indicate grape samples.</p
