Encodes a protein involved in the dephosphorylation of phosphorylated phytochromes.
Overexpression of Pisum sativum FYPP
leads to an early flowering-time phenotype under LD conditions only. [Kim et al., 2002] RNA interference:
Overexpression of an antisense transcript of FYPP
leads to early flowering under LD conditions only. ( Transgenic lines also seem to be very slightly early flowering under SD conditions. The antisense overexpressing line has decreased expression levels of both FYPP1
.) [Kim et al., 2002] Function:
Dephosphorylates phosphorylated phytochromes, with a preference toward Pfr forms. Plays a major role in the photoperiodic control of flowering time in long days by modulating phytochrome signals in flowering time control (By similarity). [Data from UniProt]
