| الوصف: | International audience ; MADS transcription factors are present in all eukaryotes, but in flowering plantshave undergone a significant expansion over the course of evolution. MADSTFs fulfill many roles in the plant, most notably acting as key regulators offlowering and floral organ development. MADS TFs bind DNA as obligatedimers in animals and fungi. However, in plants, MADS TFs have acquired atetramerization domain, which allows, in addition to the formation of dimericcomplexes, the formation of tetrameric complexes that can bind to two cognatesites simultaneously. In angiosperms, the SEPALLATA (SEP) subfamily ofMADS transcription factors act as organizers of MADS complexes, forming bothheterodimers and heterotetramers in vitro. Whether DNA-binding bySEPALLATA-containing dimeric MADS complexes are sufficient for launchingfloral organ identity programs or whether tetramerization is mandatory was notyet established in vivo. In order to address the fundamental question of thephysiological role and requirement of tetramerization in flower development, weperformed structural, genome wide, biochemical, and in vivo experiments tocorrelate oligomerization state with DNA-binding and physiological function.Using structure-based design, we generated two MADS (SEP3 andAGAMOUS) mutants with strongly abrogated tetramerization capability, but thatretain the capacity to dimerize and bind DNA. In this way, we could decoupletetramerization from DNA binding and clearly show, that tetramerization isessential for the activity of MADS TF complexes in vivo in petal, stamen andcarpel development in Arabidopis thaliana. |
