Either bZIP60 S or bZIP60ΔN S can rescue the virus suppression phenotype of the <i>bzip60-2</i> mutant.

<p><b>(A)</b> Phenotypes of the wild-type, the transgenic lines of <i>pbZIP60-bZIP60</i> S and <i>pbZIP60-bZIP60ΔN</i> S and the <i>bzip60-2</i> mutant at 18 dpi after inoculation with buffer or TuMV. Note that both transformants developed typical TuMV symptoms, compared to the wild type and <i>bzip60-2</i> mutant. <b>(B)</b> qRT-PCR analysis of TuMV <i>CP</i> mRNA levels. At 18 dpi after inoculation with buffer or TuMV, RNA was extracted from systemically infected leaves, and qRT-PCR was carried out. <i>Actin II</i> was used as an internal control. Data represent means with SD of three biological replicates. ** <i>P</i><0.05, unpaired two-tailed Student’s test. ns, non-significant.
