Expression analysis of target transcripts in turnip and oilseed rape. Relative expression levels of (a) Rubisco activase (RCA) transcripts, (b) senescence‐associated protein (SAP) transcript, (c) heat shock protein‐70 (HSP70‐1) transcripts, (d) light harvesting complex protein 1.3 (LHCB1.3), and (e) CP5 transcripts in selected tissues of mock‐treated (M) or cauliflower mosaic virus (CaMV)‐infected turnip and oilseed rape plants. (f) Relative expression levels of transcripts of major RNA silencing factors, RNA‐dependent RNA polymerase 1 (RDR1), Dicer‐like 4 (DCL4), Argonaute 2 (AGO2), and Dicer‐like 2 (DCL2) in selected tissues of mock‐treated or CaMV‐infected turnip and oilseed rape plants. Data are shown as the mean value ± SD from three independent assays using Student’s t‐test (*, P < 0.05; **, P < 0.01). bra, Brassica rapa; bna, Brassica napus.
