TL;DR: FLOWERING LOCUS T (FT), which acts in parallel with the meristem-identity gene LEAFY (LFY) to induce flowering of Arabidopsis, was isolated by activation tagging and the deduced sequence was similar to the sequence of TERMINAL FLOWER 1 (TFL1), an inhibitor of flowering that also shares sequence similarity with membrane-associated mammalian proteins.

TL;DR: Activation tagging using T-DNA vectors that contain multimerized transcriptional enhancers from the cauliflower mosaic virus (CaMV) 35S gene has been applied to Arabidopsis plants, and it is shown that overexpressed genes are almost always found immediately adjacent to the inserted CaMV 35S enhancers.

TL;DR: The results indicate that AGL20 is an important integrator of three pathways controlling flowering in Arabidopsis, and is positively regulated not only by the redundant vernalization and autonomous pathways of flowering but also by the photoperiod pathway.

TL;DR: It is demonstrated that Arabidopsis SHORT VEGETATIVE PHASE (SVP) plays an important role in the response of plants to ambient temperature changes and it is proposed that this is one of the molecular mechanisms that modulate flowering time under fluctuating temperature conditions.

TL;DR: Genetic and expression analyses suggest that CO activates SOC1 through FT to promote flowering in Arabidopsis, indicating that FT is required for SOC1 induction by CO.
