RDR6 mediates nonhost defense against TYLCCNV in <i>Arabidopsis</i>.

<p>(<b>A</b>) Symptoms of wt (Col-0) and <i>rdr6-11 Arabidopsis</i> plants infected by 10A and 10Aβ at 30 dpi. (<b>B</b>) Southern blot analysis of viral DNAs of 10A and 10β in systemically infected leaves of Col-0 and <i>rdr6-11</i> plants at 30 dpi. The total DNA agarose gel was stained with ethidium bromide to show the equal loading. Viral single-stranded DNA (ssDNA) and supercoiled DNA (scDNA) forms are indicated.
