Methylation Level Directly Influences DCL4NLS
TSS Usage in Transgenic Plants.
(A) Methylation analysis of the transgenic DCL4 promoter in independent transgenic lines, including ProDCL4:DCL4-mCherry, whose expression is depicted in Figure 2F, compared with the endogenous promoter of wild-type Col plants, measured by sequencing of bisulfite-converted DNA. Graphs depict averages with error bars showing 95% Wilson score confidence intervals. Number of cloned sequences analyzed is indicated in Supplemental Figure 11.
(B) Relative expression by qRT-PCR of DCL4NLS normalized to total DCL4 in Col and transgenic seedlings. Mean ± se of three independently harvested biological replicates, each with three technical replicates shown. **P value < 0.01 and ***P value <0.001, as determined by a pairwise two-tailed t test compared with Col.
