Characteristics of the clusters in galls (G) and uninfected roots (R) libraries at 7 and 14 dpi. a Average characteristics for the three libraries of each condition (G7, R7, G14 and R14): (1) translated SOLiD color spaced reads mapped on a A. thaliana genome; (2) reads mapped on the genomic regions associated with siRNA accumulation (clusters) on A. thaliana genome; (3) mean number of clusters per condition; (4) reads mapped on clusters with a Dicer Call (DC-clusters) i.e. when more than 80% of reads on the cluster have a size between 20 and 24 nt; (5) mean number and (6) proportion of DC-clusters; (7) DC-cluster mean size (nt) and (8) mean abundance of reads by DC-cluster. The data for each library are presented in Additional file 2: Table S1. b Stacked bar charts of the number of the various categories of DC-clusters (20, 21, 22, 23, 24 nt) for each condition. The proportions of each category are also presented
