Core Viewpoint - The research published in Nature highlights a new mechanism for the formation of the Florigen Activation Complex (FAC) and its distinct functions during the development of the shoot apical meristem (SAM) and floral primordia [6][7]. Group 1: Research Findings - The study demonstrates various mechanisms of FAC assembly, the multiple functions of 14-3-3 proteins within the complex, and the unexpected spatiotemporal distribution of FAC [6]. - FT interacts with the DNA-FD-14-3-3 complex through two interfaces, with one interface involving the intrinsically disordered C-terminus of FT binding to DNA [6]. - The interaction between 14-3-3 proteins and the phosphorylated C-terminus of FD reduces the liquid phase condensation of the intrinsically disordered FD protein, enabling it to bind DNA [6]. - The research team discovered that during the early developmental stage of floral primordia, FT and FD co-transcribe in the young floral primordia, forming a repressed boundary of bracts, which leads to the formation of FAC in the initial stages of flower development [6]. Group 2: Author Background - Gao He, a co-corresponding author of the study, graduated from Jilin Agricultural University in 2007 and obtained a PhD from Nanjing Agricultural University in 2012, later conducting postdoctoral research at the Max Planck Institute for Plant Breeding Research [5].
