Research Abstract

To ensure reproductive success, plants have to regulate the timing of the floral transition. Genes in which the insertions located have been renamed FLORAISON TARDIVE1(FLA1) and FLA2. These fla1 and trp mutants grown on medium containing higher concentration of tryptophan did not display any late flowering phenotype suggesting that FLA1 affect the floral transition through a new tryptophan pathway.
Concerning FLA2, FLA2 is also known as TUBBY LIKE PROTEIN4(TLP4) and is a member of an eleven genes family, TLP1 to TLP11. Mutants of eight of these genes displayed a similar late-flowering phenotype asfla2/tlp4. TLPs seem to regulate expression of the autonomous genes in a redundant way.
