WebOct 24, 2024 · For example, Brambilla et al. used CRISPR/Cas9 to confirm the role of two bZIP transcription factors, Hd3a BINDING REPRESSOR FACTOR 1 (HBF1) and HBF2, in downregulating the rice flowering-promoting genes Early heading date 1(Ehd), Heading date 3a (Hd3a), and Rice Flowering Locus 1(RFT1) (Fig. 1). WebFeb 14, 2024 · In addition, two additional bZIPs, including Hd3a BINDING REPRESSOR FACTOR1 (HBF1) and HBF2, form alternative FACs with the florigens and reduce Hd3a and RFT1 expression to delay flowering. This situation suggests that Hd3a and RFT1 can regulate their own expression in leaves through forming antagonistic transcription factor …
Transcription factor bZIP65 delays flowering via …
WebHere, we show that Hd3a and RFT1 can form transcriptional activation or repression complexes also in leaves, and feed-back to regulate their own transcription. Activation complexes depend upon OsFD1 to promote flowering. However, additional bZIPs, including Hd3a BINDING REPRESSOR FACTOR 1 (HBF1) and HBF2 form repressor complexes … WebHere we show that the rice FT homologue Hd3a interacts with 14-3-3 proteins in the apical cells of shoots, yielding a complex that translocates to the nucleus and binds to the Oryza sativa (Os)FD1 transcription factor, a rice homologue of Arabidopsis thaliana FD.

WebWhen lactose is not available, the repressor will bind to allolactose. d. In the absence of lactose, transcription occurs at a low level resulting in the production of allolactose, which in turn stimulates the cell to take up lactose. e. When lactose is available, allolactose is produced and binds to the operator, blocking RNA polymerase. community coaching course basketball
