The binding of strigolactones to their receptor, the alpha/beta hydrolase DWARF14 (D14), leads to the modulation of transcriptional activity by destabilization of specific transcriptional corepressors via proteasomal degradation. Subsequently, strigolactones also promote D14 degradation by the same pathway. Here we describe an innovative quantitative bioassay based on Arabidopsis transgenic lines expressing AtD14 fused to the firefly luciferase, developed to identify new strigolactone analogs capable to activate the strigolactone signaling.
