Analysis of RDR2-dependent endogenous siRNAs content in dcl mutants. RNA gel blots analysis of 10 μg total RNA prepared from inflorescence of wild-type Col, and dcl1, dcl2, dcl3, dcl4, dcl2 dcl3, dcl2 dcl4, dcl3 dcl4, dcl2 dcl3 dcl4, dcl1 dcl2 dcl3 dcl4. The blots were probed with DNAs complementary to siRNAs and U6, which served as a loading control.
