Accumulation of the different classes of ex-siRNAs in the ago-1− mutant.

aAverage value of the log2 fold change of the different classes of ex-siRNAs in the ago-1−M. circinelloides mutant compared to wild type. Log2 fold changes in Table S3 were used to calculate the average. Only values higher than 3-fold down-regulation in the corresponding mutants relative to wild type are indicated. Dependence on dicer and rdrp genes of ex-siRNAs from each class is shown.
