Fig. 4. Expression of RFT1 in Hd3a RNAi plants under SD conditions. (A) Expression of Hd3a in Hd3a RNAi and wild-type plants. Hd3a expression was suppressed at all developmental stages in Hd3a RNAi plants. (B) Expression of RFT1 in Hd3a RNAi and wild-type plants. RFT1 transcription was very low in wild-type plants (black line). However, in Hd3a RNAi plants, RFT1 expression (green, blue and red lines) had increased 30 days before flowering, the stage required for promoting reproductive transition. Leaves were collected from wild-type plants and Hd3a RNAi plants at 35, 50, 70 and 90 DAS (ZT 0) under SD conditions.
