Transcriptional regulator required for the maintenance of the plant vegetative phase. In association with CHR11 or CHR17 may prevent the early activation of the vegetative-to-reproductive transition by regulating key genes that contribute to flower timing, such as FT, SEP1, SEP3, AGL8/FUL, SOC1 and FLC. Interacts with CHR11 and CHR17 (PubMed:22694359). Interacts (via the DDT domain) with CHR11 (via C-terminus) (PubMed:23691993). Highly expressed in growing tissues such as inflorescence and flower meristems, young leaves and floral organs. Expressed in roots, rosette and cauline leaves, stems, flowers, inflorescences and siliques. No visible phenotype under normal growth conditions, but the double mutant plants rlt-1 and rlt2-1 are small and display early flowering.
