<p>PSTVd infected plants were analyzed at 3wpi. (A) Representative northern blots of (a) DCL2.11(x)3.10i, (b) DCL2.11(x)3.1i, (c) DCL3.10(x)2.41i and (d) DCL3.10(x)2/4.5i, DCL2/4.5(x)3.10i crosses. Total RNA staining (methylene blue) was used as loading control. Northern blots were quantified with Quantity One 4.4.1 software and are presented in (B). ‘n’, number of plants quantified. Student <i>t</i>-test was performed and significance levels were set as following: p<0.05 (*), p<0.01 (**) and p<0.001 (***).</p
