Fig. 2. RFT1 expression is localized in leaf vascular tissues.
(A,B) Quantitative RT-PCR analysis of Hd3a and
RFT1 expression in rice tissues under SD conditions. RFT1
and Hd3a were expressed in leaf blades (LB), but not in leaf sheaths
(LS) or roots (R). Leaf blade, leaf sheaths and roots were collected from
wild-type plants grown under SD conditions 35 DAS (ZT 0). (C)
RFT1 promoter activity in RFT1::GUS transgenic
plants. Transverse leaf section in RFT1::GUS plants 35 DAS
under SD conditions (ZT 4). Scale bars: 20 µm.
