FLOWERING LOCUS T has higher protein mobility than TWIN SISTER OF FT.

Jin S, Jung HS, Chung KS, Lee JH, Ahn JH - J. Exp. Bot. (2015)

Bottom Line: In plants, successful reproduction requires the proper timing of flowering under changing environmental conditions.Previous work has shown that FT is graft-transmissible; by contrast, this study did not detect movement of TSF from the roots into the shoot of the scion plants.Taking these results together, we propose that protein mobility of FT is higher than that of TSF, possibly due to a protein domain that confers mobility and/or protein stability.

Flowering times of homozygous transgenic plants overexpressing FT/TSF chimeric proteins. Distribution of flowering time of FT/TSF chimeras under LD conditions, presented as a heat map. The structure of each chimeric gene is shown next to the name of each construct. Sequences of FT and TSF are shown as grey and open boxes, respectively. n = number of plants measured. F: region originating from FT; T: region originating from TSF.

Figure 2: Flowering times of homozygous transgenic plants overexpressing FT/TSF chimeric proteins. Distribution of flowering time of FT/TSF chimeras under LD conditions, presented as a heat map. The structure of each chimeric gene is shown next to the name of each construct. Sequences of FT and TSF are shown as grey and open boxes, respectively. n = number of plants measured. F: region originating from FT; T: region originating from TSF.

Mentions: The flowering time of homozygous plants from each line was measured under LD conditions. Most chimeras showed strong acceleration of flowering under LD conditions, similar to that seen in FT- and TSF-overexpressing plants (Fig. 2). TFF, FFT, TTF, and TFT were as effective at accelerating flowering as authentic FT or TSF. However, the FTT chimera was slightly less effective. Notably, none of the lines showed delayed flowering or unaltered flowering, suggesting that cosuppression or instability of chimeric proteins did not occur. These results indicated that these chimeras were functional in transgenic plants and acted in a similar way to parental FT and TSF.
